Abstract

The invention discloses a melon vegetable winter seedling growing method and a seedling growing agent matched with the method. The melon vegetable winter seedling growing method and the seedling growing agent aim at overcoming the defects that winter seedling growing is difficult, freeze injury and diseases are generated easily, and the seedling growing success rate is low. The sky and earth film coverage seedling growing mode is adopted and matched with the seedling growing agent to achieve heat preservation, dehumidification and disease prevention. Compared with a conventional seedling growing method, the ground temperature of a seedbed is made to be increased by 4-8 DEG C, the humidity in a greenhouse can be reduced by 25-35%, and freeze injury and diseases can be effectively prevented due to the medicine function of the seedling growing agent. The melon vegetable winter seedling growing method and the seedling growing agent can improve the seedling growing success rate to be more than 96%, the seedling growing cost is low, and the technology is easy to master.

Description

A kind of gourd vegetables seedling-cultivating method in winter and nursery agent

Technical field

The present invention relates to a kind of gourd vegetables seedling-cultivating method in winter and adopt the necessary nursery agent that there is insulation, moisture absorption and prevent disease from occurring of the method.

Background technology

Gourd vegetables is liked temperature, throbs with fear cold but be afraid of high temperature, and preference temperature of its growth is 20 ~ 30 DEG C, generally higher than 35 DEG C of poor pollination, easily causes metabolic disorder lower than 10 DEG C, just freeze injury can occur time below 5 DEG C.The thermophilic phase of bloom to extend these type of vegetables, bearing fruit and ahead of time harvest time, China generally adopts heat cradle, heating wire hotbed, natural ferment material hotbed etc. to cultivate seedling at present.After these seedlings cultivate, then plastic foil covering cold bed is adopted to divide seedling to heel in, with cultivating large seedling.Although the advantage such as adopt the method cultivating large seedling to have reduced investment, not consume energy, but be generally all in December and this period of the coldest annual season of January next year owing to heeling in the phase, canopy humidity is large, seedbed ground temperature is low, seedling is in not only in the cold but also growing environment of high humility in plastic greenhouse, the incidence of disease is high, the impact of climatic variation in addition.Slightly neglect and just seedling frame can be caused all dead because of freeze injury or disease.Therefore, adopt that the method cultivating large seedling nursery difficulty is large, poor reliability.Generally the success rate of nursery only has about 40%.This not only increases seedling cost, and directly has influence on the production of gourd vegetables and the income of vegetable grower after the spring.

Summary of the invention

Technical problem to be solved by this invention is: providing one to receive physioclimate affects less, is easy to the seedling-cultivating method cultivating gourd vegetables seedlings winter of grasp and adopts the necessary nursery agent having insulation, moisture absorption and prevent damage by disease and insect from occurring of the method.

For solving the problems of the technologies described above, the technical solution used in the present invention is: the seedling-cultivating method in winter of a kind of gourd vegetables, the cultivating large seedling such as comprise employing " my god, plastic mulching " and timing ventilation is ventilative, the water droplet that canopy film dries Miao Yeshang is opened when heeling in after seedling survives, layer overlay nursery agent equably on mulch film simultaneously between plant, and regularly take off canopy ventilation drying and dry nursery agent to recover its hygroscopicity.

Described nursery agent be by ash, quicklime and topsin by weight percentage 10:0.8 ~ 1.4:0.4 ~ 0.7 Homogeneous phase mixing form.

The invention has the beneficial effects as follows: by applying this seedling-cultivating method and nursery agent thereof, reducing technical difficulty and the cost of nursery in winter, improve success rate and the reliability of nursery.Compared with conventional seedbed system method, under same environmental conditions, bed temperature can improve 4 ~ 8 DEG C.Therefore, though temperature of shed be in 0 DEG C even in short-term a little less than 0 DEG C time, the kilter that because ground temperature is higher, plant is still in " pin heat, cool ", this enhances the cold tolerance of top plant, and unlikely generation freeze injury; Again due to the hygroscopic effect of nursery agent, the relative moisture in canopy generally can reduce by 20 ~ 30 DEG C, the effect of the reduction of humidity and topsin and quicklime, greatly reduces again and prevent the generation of disease.Adopt the present invention, nursery success rate generally can be made to bring up to more than 96%, improve about 40% compared with the success rate of conventional seedbed system.

Embodiment

Embodiment 1:

The preparation of nursery agent: get hay wood ash 15kg, quicklime 1.5kg, topsin 0.8kg, mixes rear stand-by.

For cucumber seedling: canopy nursery during the present embodiment adopts, seedbed area is 8 × 6m.The foundation of middle canopy and the regulation in seedbed, sterilization, the using of base manure, carry out all routinely.Bed surface, slightly in watt antiform, is close in order to mulch film in surface, seedbed, in advance plastic film mulch shed.When the seedling brought out by hotbed grows to 4 ~ 6 true leaves, move in canopy and heel in, expose mulch film and plant in the soil pit in seedbed by seedling, every cave two strain when heeling in pocket knife, cave is square apart from 7 ~ 8cm.Ground fenestra is the smaller the better.With a small amount of fine earth, aperture is sternly stifled after carrying good seedling, vexed canopy temperature raising immediately after having planted, takes off canopy film again and dries seedling leaf water droplet after seedling survives, simultaneously by mulch film between seedling of the nursery agent uniform spreading for preparing, and shake off the nursery agent dust dropped on cauline leaf gently, then lid upper greenhouse.The total consumption 17.3kg of nursery agent, every square meter is about 360g.Adhere to more than 10 DEG C to take off canopy film without rainy day gas ventilated, until field planting of transplanting seedlings.Mulch film transplantation with soil can be torn during field planting.The cucumber seedlings that the present embodiment is cultivated about can for 1.5 mu of land for growing field crops seedlings.

Embodiment 2:

A) first green pepper seed is scalded kind of a 20min in the water of 55 DEG C;

B) above-mentioned boiling hot seed of planting is soaked 1.5h in warm water;

C) the seed clear water after soaking is air-dry after rinsing 5 ~ 6 times;

D) by above-mentioned air-dry after seed in the Gibberellins solution of 500 ~ 800ppm, soak 30h, wherein, the consumption of Gibberellins solution is 4 times of seed weight, can use after air-dry.

Claims

1. the seedling-cultivating method in winter of a gourd vegetables, the cultivating large seedling such as comprise employing " my god, plastic mulching " and timing ventilation is ventilative, it is characterized in that: open when heeling in after seedling survives the water droplet that canopy film dries Miao Yeshang, layer overlay nursery agent equably on mulch film simultaneously between plant, and regularly take off canopy ventilation drying and dry nursery agent to recover its hygroscopicity.

2. gourd vegetables seedling-cultivating method in winter according to claim 1, is characterized in that: described nursery agent be by ash, quicklime and topsin by weight percentage 10:0.8 ~ 1.4:0.4 ~ 0.7 Homogeneous phase mixing form.
