the water and fertilizer are completely nutrient solution (EC 1.8mS cm)-1pH 5.5), spreading cotyledon, spraying water every 1-2 days, and fertilizing with nutrient solution (EC 2.0mS cm)-1pH 5.5), irrigation amount is determined according to the substrateThen the method is finished;
the method is characterized in that the constant temperature and humidity are mainly used in seedling emergence during sowing, the temperature is 28-30 ℃, the day temperature is controlled to be 25-28 ℃ after seedling emergence until the two leaves are in one heart, the night temperature is controlled to be 18-20 ℃, the day-night temperature difference needs to be gradually increased after the two leaves are in one heart, the day temperature is kept to be 25-28 ℃, the night temperature is reduced to be 15-18 ℃, and meanwhile, the air humidity is controlled to prevent the excessive growth of seedlings.
Preferably, in step S4, robust and uniform seedlings are selected during planting, the seedling multi-span seedling substrate is placed into the cultivation bag, and the planting density is 2.78 plants/m2Starting an irrigation system after field planting, starting primary irrigation when the weight of the matrix bags is reduced by 50% in the initial field planting stage, and completely watering the matrix bags; after the seedlings survive, the irrigation quantity is gradually increased.
Preferably, in step S5, the plant management includes:
(1) vine hanging device
When the seedlings of the melons are planted for 9-11 days by 25-30 cm, vine binding is completed by using vine binding ropes, vine binding is performed on the base of the stems of the netted melons, and then seedling winding is performed every week to maintain the vertical growth of the melons;
tying the vine tying rope on the upper steel wire in the greenhouse corresponding to the melon planting position in advance, and then tying the rope at the base of the melon stem in an 8-shaped buckle mode;
(2) around vine
Winding the vine, namely winding the head of the plant on a lifting rope clockwise, and winding the vine 1 time per week after the vine is lifted so as to ensure the vertical growth of the melon;
(3) branching device
Forming the seeds and the vines of the netted muskmelons, pruning a single vine, and keeping the main vine to grow until 25-30 leaves of the main vine are pinched; removing lateral tendrils below 12 sections of the main tendrils and lateral tendrils, male flowers and tendrils outside the reserved fruit-bearing lateral branches;
(4) fruit branch of Sichuan melon
Reserving 3 lateral branches on 12-14 leaves of the main vine 1-2 days before blooming, and reserving 1-2 leaf pinching parts after the second section of the lateral branch is seen in a melon embryo;
(5) pollination is carried out
Pollinating by using bumblebees, thoroughly killing insects and bacteria in a greenhouse 5 days before female flowers open, feeding bees 2-3 days before the female flowers open, and recording pollination time to correctly deduce the mature period of fruits;
(6) sparse melon
When 70-80% of melon fruits grow to the size of eggs, selecting strong lateral vines without being damaged by pests and remaining fruits, and removing the rest two fruits together with the vines;
(7) snake gourd
The operation of hanging the melons is carried out after the melons are left, a special melon hanging hook is used for hanging the melons between the melon stalks on the lateral vines, the melons are hung up longitudinally, the melons are raised by 25-35 degrees, the heights among the plants are kept consistent, and the leaves are staggered;
(8) cover bag for shading
The bagging is carried out when the fruit enters a quick expansion period of 220g and 180-;
(9) pinching and topping
When 18 leaves of the main vine grow to have a core, removing growth points with the size of 4-6mm, and breeding 4-6 true leaves on the upper part after core picking; when the fruit grows to the size of eggs, timely removing cotyledons of the base part and 3-4 true leaves above the cotyledons, keeping 10 true leaves below a fruit node of the whole stem and vine and 8-10 true leaves above the fruit node, and promoting the conversion from vegetative growth to reproductive growth;
(10) harvesting
Before the temperature in the greenhouse rises in the morning, the bearing branches and the shading bag are cut off together, and then the bearing branches and the shading bag are packaged in a shade place in a grading way; then the mixture is placed in a shade cold place or a cold storage at the temperature of 8-13 ℃ for 3-5 days for eating.
Preferably, in step S6, in different climates and different plant growth stages, the precise regulation and control of plant water and fertilizer management is realized by adjusting the formula and concentration of the nutrient solution and the irrigation method;
(1) nutrient solution formula management
The preparation of the nutrient solution adopts simple substance fertilizers to mix according to the formula, and the formula is adjusted in time according to the growth vigor of plants in different growth periods and the detection result of the nutrient solution in the production so as to meet the growth demand of the plants;
(2) nutrient solution and effluent EC and pH management
In order to ensure the irrigation accuracy, the EC value and the pH value of irrigation liquid and discharge liquid need to be monitored every day, and the discharge liquid amount after the melons are planted is 25-30% of the irrigation amount; the demand of the muskmelon on the EC values of irrigation liquid and discharge liquid in different growth periods is different, the EC value of the nutrient liquid needs to be accurately controlled, and the EC value of the irrigation liquid is less than 3.0mS cm-1；
In the later growth period, along with the increase of the temperature, the EC value of the nutrient solution is reduced, and the irrigation quantity is increased; when the temperature is lower, the EC value of the nutrient solution is increased, the pH value of the nutrient solution is 5.5-6.0, and the pH value of the discharged liquid is 6-6.8;

TABLE 1 temperature and humidity management indexes of netted melon in different seedling stages
Third, cultivation mode
And (3) cultivating the coconut shreds by adopting a bracket type cultivation groove and a bag type (the capacity is 6L) cultivation bag and a fine coconut coir-perlite-3: 1 cultivation medium (the length of the fine coconut coir shreds is 0-5 mm). Ensure the water retention and permeability of the matrix.
Fourthly, planting
And (3) sterilizing the environment in the greenhouse, supporting equipment and a cultivation system before field planting, cleaning the cultivation liquid supply system, preparing a nutrient solution, and trying an irrigation system. Mixing the fine coconut chaff after soaking and the perlite according to a ratio, filling the mixture into a cultivation bag, and controlling the pH value to be 5.5 and the EC value to be 3.0mS cm-1The complete nutrient solution permeates the substrate, and then the field planting can be carried out.
Selecting strong and uniform seedlings during field planting, putting the seedling multi-span seedling substrate into a cultivation bag, and setting the field planting density to be 2.78 plants/m2(2 strains/bag). And starting an irrigation system after field planting, wherein excessive irrigation is not needed in the initial field planting stage, and once irrigation is started when the weight of the matrix bag is reduced by about 50 percent, so that the matrix bag is thoroughly irrigated. After the seedlings survive, the irrigation quantity is gradually increased.
Fifth, plant management
The netted melon is cultivated by seedling hanging, a melon retaining mode of 'one vine and one melon' is adopted, and the specific links and operation standards of plant management are as follows:
5.1 hanging vine
And when the sweet melon seedlings grow for 25-30 cm after 10 days of field planting, vine binding is completed by using vine binding ropes, vine binding is performed on the base parts of the netted melon stems, and then, the seedlings are wound every week to maintain the vertical growth of the melons. The specific operation is as follows: the vine binding ropes are tied on the upper steel wires in the greenhouse corresponding to the melon planting positions in advance, and then the ropes are tied at the base of the melon stem in an 8-shaped buckle mode. The space can be reserved along with the increase of the plant in the later stage by the slipknot, so that the plant is prevented from being tightened, and the transportation of nutrient substances is prevented from being influenced. During operation, attention needs to be paid to avoid the friction between the rope and the stem, the damage to the epidermis of the stem and the infection caused by the friction; meanwhile, the length of the rope for winding the seedlings needs to be paid attention to avoid over-tightening and seedling winding, and the rope is preferably slightly slouched after the seedlings are tied.
5.2 winding tendril
The head of the plant is wound on the lifting rope in a clockwise direction (the direction of the worker is consistent with the direction of the plant around the vine every time), and the vine is wound 1 time per week after the vine is lifted, so that the melon can grow vertically. When winding tendrils, attention should be paid to avoid the damage of the ropes to plant growing points.
5.3 twitch
And (3) enabling the netted melon seeds and tendrils to bear melon, performing single tendrils pruning, and keeping the main tendrils to grow until 25-30 leaves of the main tendrils are pinched. The lateral tendrils below the 12 sections of the main tendrils and the lateral tendrils, male flowers and tendrils outside the lateral branches of the reserved fruit are all removed as early as possible. The branch should be removed from the branch base to reduce the mechanical injury and promote the wound healing.
5.4 shoot of Cucumis sativus
And (3) reserving 1-2 more leaves for pinching after the second section of the lateral branch is seen in the melon embryo from 12-14 leaves of the main vine (1-2 days before blooming).
5.5 pollination
Pollinating by using bumblebees, thoroughly killing insects and bacteria in the greenhouse 5 days before the female flowers open, feeding bees 2-3 days before the female flowers open, selecting a Biott import medium beehive, and keeping 6 boxes of bees in the greenhouse for 1 ten thousand square meters. In order to avoid direct sunlight on the beehive, the beehive is placed under a cultivation groove, a sunshade net is adopted for shading, and pollination time is recorded so as to correctly deduce the mature period of the fruit. During the bee keeping period, pesticide and bactericide is prohibited to be sprayed in the greenhouse.
5.6 thinning melon
When 70-80% of melon fruits grow to the size of eggs, selecting strong lateral branches without damage of pests and fruits with strong lateral vines to retain fruits, and removing the rest two fruits together with the subsidiary vines. When thinning the melon, the leaf is mainly prevented from being scratched to leave the surface of the melon so as to avoid forming scars.
5.7 Trichosanthes kirilowii
The operation of the snakegourd is carried out after the snakegourd is left, a special snakegourd hook is used for hanging the snakegourd between the snakegourd handles on the lateral tendrils and longitudinally hoisting the snakegourd, the height of the snakegourd is about 30 degrees as much as possible, the height among plants is consistent as much as possible, and the blades are staggered to prevent the skins of young fruits from being rubbed by the wind-shaking blades. By doing so, the fruit branch and the upper main vine can be prevented from being broken after the fruit is expanded, and the dropping of the melon can be avoided.
5.8 bagging for shading
The bagging is carried out when the fruit gets into quick expansion phase, 200g about, winds the handle a week with the melon bag of cover at the top of fruit, and it can to twine fixedly gently, can prevent that the blade from rubbing the peel on the one hand doing so, and on the other hand can prevent that photic inequality from influencing the outward appearance of fruit peel, causes pollution and injury to the fruit when can also preventing the chemical control disease.
5.9 pinching and topping
When 18 leaves of the main vine grow to have a core, growing points with the size of about 5mm can be removed (4-6 true leaves are still bred and grown on the upper part after the core is picked). And (3) timely removing cotyledons of the base part and 3-4 true leaves above the cotyledons when the fruits grow to the size of eggs, keeping 10 true leaves below the fruit nodes of the whole stem and vine and 8-10 true leaves above the fruit nodes, and promoting the conversion from vegetative growth to reproductive growth.
5.10 harvesting
The netted melon has the fruit appearance which is difficult to judge the harvest optimum period, and when the multi-span greenhouse is produced in a large scale, the melon can judge whether the fruit is mature or not by adopting the following two modes: the first is that according to the appearance of the fruit, the leaves of the lateral branches of the fruit gradually turn into yellow brown, the periphery of the fruit base is changed from green to yellow-green, and the cross hatch is changed from white to yellow-white, so that the fruit can be judged to be ripe; the second method is sugar degree measurement, the muskmelon is ripe after 45-48 days of spring and autumn type muskmelon blossom, the autumn and winter type is about 50 days, the soluble solid content can be sampled and detected in different areas in a greenhouse according to days after blossom, and the proper harvesting period is about 15% of the common content.
During collection, the bearing branches and the shading bags are cut off together before the temperature in the greenhouse rises in the morning as much as possible, and then the bearing branches and the shading bags are packaged in a graded manner in a shade place. The netted melon is not optimal in taste and mouthfeel after being picked, and generally needs to be eaten after being post-cooked for 3-5 days at a shade cold place or in a cold storage at 8-13 ℃.
Sixthly, water and fertilizer management
The multi-span greenhouse is produced in an industrialized mode by adopting an accurate irrigation management system, and accurate supply of water and fertilizer can be achieved. Different from the irrigation mode of conventional soil cultivation, the industrialized production needs a small amount of multiple irrigation. Generally, 2 aspects of nutrient solution formula, concentration and irrigation strategy jointly influence the growth of crops. In different climates, different plant growth stages, through the continuous adjustment to above 2 aspects, realize the accurate regulation and control to plant liquid manure management.
6.1 nutrient solution formula management
The nutrient solution is prepared by mixing simple substance fertilizers according to a formula, and the formula is adjusted in time according to the growth vigor of plants in different growth periods and the detection result of the nutrient solution in production so as to meet the growth demand of the plants. In production, plant growth vigor and detection results are integrated, and a nutrient solution formula system for multi-span greenhouse netted melon coconut husk cultivation is initially established (table 2).
TABLE 2 nutrient solution formula for netted melon in multi-span greenhouse in different growth periods
6.2 nutrient solution and effluent EC and pH control
In order to ensure the irrigation accuracy, the EC value and the pH value of the irrigation liquid and the discharge liquid need to be monitored every day, and the discharge liquid amount after the melons are planted is 25-30% of the irrigation amount. The demands of different growth periods of the netted melon on the EC values of irrigation liquid and discharge liquid are different (Table 3), so that the EC value of the nutrient solution needs to be accurately controlled in the cultivation process of the melon, the large fluctuation of the EC value is avoided as much as possible, and the EC value of the irrigation liquid is generally less than 3.0mS cm-1. The concentrations of the nutrient solutions in different seasons are different, and the EC value of the nutrient solution can be properly reduced and the irrigation amount can be increased along with the rise of the temperature in the later growth stage; when the temperature is lower, the EC value of the nutrient solution can be properly improved. The pH value of nutrient solution suitable for the growth of the muskmelon is 5.5-6.0, and the pH value of discharge solution is 6-6.8.
TABLE 3 melon growth period irrigation and discharge concentration requirements (mS cm) for different muskmelon growth periods-1)
6.3 irrigation strategy
The irrigation strategy comprises 3 aspects of irrigation quantity, irrigation time and irrigation frequency.
The total irrigation amount is the total nutrient solution supplied to the melon plants within 1 d. Determination of Total amount of melon irrigated reference Dutch tomato irrigation model (1J. cm)-2＝3mL·m-2) And simultaneously, the water content of the matrix and the liquid discharge amount of each irrigation are combined for adjustment. Generally, under sunny conditions, after the last 1 irrigation, the water content of the substrate is increased by 5-10% compared with that before the irrigation, and the liquid discharge amount is preferably up to 30%. The total amount of muskmelon irrigated in different periods isDifferent (table 4).
In 2020, factory production of multi-span greenhouse netted melon in small-mountainous-area agricultural scientific and technological display base is from seedling stage to netted line formation, the total irrigation amount is continuously increased, the irrigation amount after the netted line formation is reduced, and the average daily irrigation amount in the seedling revival stage after field planting is 50-100 ml per plant-1The average irrigation amount from seedling revival to flowering period is 200-500 ml per plant-1The daily average irrigation amount from flowering to fixed melon period is 800-1000 ml per plant-1After melon is fixed, the daily average irrigation quantity is 1200-1500 ml per plant till longitudinal striation appears-1The daily average irrigation quantity of the fruit in the fruit expanding period is 1800-2200 ml per plant-1The amount of irrigation is reduced from the formation of reticulate patterns to the harvest, and the daily average irrigation amount is 800-1000 ml per plant-1。
TABLE 5 Total irrigation amount range and actual irrigation amount of nutrient solution at different stages after melon field planting
Irrigation start and end times are critical to regulating netted melon growth. Under the multi-span greenhouse condition, the 1 st irrigation is generally set to be started about 2 hours after sunrise, the irrigation is finished about 2 hours before sunset, and the irrigation is finished about 5 hours before sunset in cloudy days.
The irrigation frequency is the irrigation frequency within 1d and the irrigation quantity of each time. Generally, the irrigation frequency in winter is low, the irrigation frequency in summer is high, and the irrigation frequency in summer can be flexibly adjusted according to the crop conditions in production. Production is set according to an illumination accumulation value (obtained by a PRIVA environmental monitoring system), and illumination is accumulated to 100-120J-cm from 1 st time before the fixed melons are produced in spring-2Starting irrigation for the 1 st time, and then, when illumination is accumulated to 120-140J-cm each time-2Starting irrigation for 1 time, setting the minimum irrigation time interval to be 25-30 min (short in sunny days and long in cloudy days), and starting the maximum irrigation time interval for 1 and half hours if the illumination is weak and the starting condition cannot be met for a long time; the water demand of the watermelon in the fruiting and fruiting expansion period rises rapidly and is set to 100J cm accumulated in the 1 st illumination-2Starting irrigation for the 1 st time, and then, every time illumination is accumulated to 75-85J-cm-2Starting irrigation for 1 time, setting the minimum irrigation time interval to be 15-20 min,the maximum irrigation time interval is 1 half hour.
In the production of netted melon in spring crops in the Shaogushan scientific and technical display base in 2020, the reticulate forming period is a key period of water and fertilizer management, and the netted melon is irrigated 20 times per day on average in sunny days and 12 times per day on average in cloudy days; irrigation was carried out 19 times a day after reticulation was formed until harvesting on sunny days and 9 times a day on cloudy days (table 6).
