Description

Comprehensive sunshading and cooling device for cress cultivation in summer

[technical field]

The present invention is that utensil is used in a kind of anti-season Chinese celery plantation, relates in particular to the comprehensive sunshading and cooling device of cress in summer plantation usefulness.

[background technology]

Chinese celery has another name called Chu Kui, is the traditional aquatic vegetable variety of China, and conventional cultivation is planted in fall or transplanting, Winter-Spring results.Along with the raising of people's living standard, the nutritional health function of Chinese celery is approved by people that more and more market demands can be produced and year-round supply in the anniversary.In recent years, many people carrying out the production trial of Chinese celery anniversary, in the anniversary planting process, plant the difficulty maximum summer of Chinese celery.Carry out the plantation of anti-season Chinese celery in summer, owing to be subjected to the influence of the too high and excessive strong illumination of environmental temperature, environment, weather conditions are difficult to satisfy the growth requirement of Chinese celery, the Chinese celery that is grown the not only color and luster of cane and leaf is bad, and the crude fiber content in the cauline leaf is too high, and tender fragility is poor, the inferior quality of Chinese celery, the edible part is quite few, and the commodity rate of Chinese celery has only 1/5th of winter.How just can cultivate Chinese celery near the quality in winter in summer, this is Chinese celery plantation difficult problem that people thirst for solving.The applicant is through studying for many years and test is found out a cover and is fit to the cress in summer cultivation method, and wherein, comprehensive sunshading and cooling device is the core of this cultivation method.

[summary of the invention]

The purpose of this invention is to provide a kind of comprehensive sunshading and cooling device for cress cultivation in summer, it is the key device that improves cress in summer plantation quality and commodity rate.

Comprehensive sunshading and cooling device for cress cultivation in summer of the present invention comprises Chinese celery planting bed, deep well, sunshading and temperature reducing canopy, micro-nozzle and water pump, and the Chinese celery planting bed is a strip, and the southeast towards, the pond is wide 2～3 meters, 20～30 meters of length; Deep well is opened in the Chinese celery planting bed or near the Chinese celery planting bed, it provides the cooling water source for the Chinese celery planting bed; The sunshading and temperature reducing canopy is included in the vertical rod on the sunny side of establishing on the ridge of sunny side, the back of the body sun vertical rod of on the ridge of opaco, establishing, the height of vertical rod on the sunny side is 90～100 centimetres, the height of carrying on the back positive vertical rod is 30～40 centimetres, in vertical rod on the sunny side with carry on the back between the positive vertical rod and set up longitudinal rod, on longitudinal rod, be fixed with micro-nozzle, micro-nozzle links to each other with the delivery port of water pump, the suction hose of water pump feeds in the deep well, between vertical rod on the sunny side, be fixed with Sun-shade screen, described Sun-shade screen is the silver gray sunshade screen cloth of sunshade rate 70%～80%, be provided with on the top of sunshading and temperature reducing canopy and other three and can receive the abat vent that can put, the material of abat vent is the silver gray sunshade screen cloth of sunshade rate 40%～55%.

Using method of the present invention is as follows:

The present invention can be to cress in summer plantation the carrying out control of illumination, temperature and depth of water, in the summer planting process, illumination control is one of key element, and cress in summer after planting, must control the illumination of Chinese celery well, specifically control principle and be: the Sun-shade screen that is fixed in the vertical rod on the sunny side maintains static; Be arranged on ceiling and other abat vent of three should carry out folding and unfolding according to weather condition, at the cloudy day or overcast and rainy, ceiling and other three face do not need cover net, for fine weather, should cover between 10 o'clock to 16 o'clock every day; Do not cover between 10 of the next mornings at 16; In the summer planting process, temperature control is another key element in the cress in summer plantation, must be to carrying out cooling protection in the Chinese celery sunshade, promptly utilizing the phreatic water micro-spray system that is provided with on sunshade that Chinese celery is carried out the timing spraying cooling handles, specific practice is: fine day, between 11 point～14, provide phreatic water by water pump to micro-nozzle, through micro-nozzle Chinese celery is carried out spraying cooling, to reduce the temperature in the frame, every 30 minutes sprays once, each 5 minutes, so just can make temperature of shed reduce by 10 ℃～15 ℃, guarantee that the maximum temperature in the canopy is no more than 26 ℃ than environmental temperature; At cloudy day or the overcast and rainy spray that do not need; For planting Chinese celery summer, also should be according to the Chinese celery growing state control depth of water, the cane of Chinese celery must all be immersed in the water, and blade tip should be controlled at 10～15 centimetres apart from the distance of the water surface, guaranteeing that Chinese celery has outside the enough photosynthesis, reduces the irradiation of light to cane as far as possible.The silver gray screen cloth that adopts different sunshade rates is as Sun-shade screen and abat vent, can reflection ray, again can sunshading and temperature reducing, and can also let in air.

The present invention has been arranged, can carry out the complex art control of illumination, temperature and humidity to the cress in summer growth, can block 70%～80% illumination towards the fixed shading in south screen, ceiling and other abat vent of three can block 50%～60% illumination, associating sunshade measure by Sun-shade screen and abat vent, can not only effectively control the illumination of cress in summer, make it to satisfy the required intensity of illumination and the quantity of illumination of Chinese celery growth, and can effectively reduce the interior temperature of frame, it is to reduce by one barrier of thermoregulation in the frame.In frame, set up little spray cooling system,, can not only in time reduce by one day temperature in the highest period frame of temperature, can increase the humidity in the frame again, two get at one stroke regularly to spraying phreatic water in the frame; The depth of water can reduce temperature in the frame in the control planting bed, can control leaf and the cane growth of Chinese celery again, improves the Chinese celery quality; The Chinese celery planting bed offer towards the southeast to strip, can improve the sunshade coverage rate of Sun-shade screen, can strengthen ventilative property in the sunshading and temperature reducing canopy again, more sharp aeration-cooling.The present invention can effectively control the illumination in the cress in summer plantation, temperature, humidity and ventilation condition, make the interior temperature of frame reduce by 10 ℃～15 ℃ than ambient temperature, the light application ratio canopy of Chinese celery has reduced by 60%～65% outward, also humidity in the frame is guaranteed, performance of ventilating is good, be more conducive to the Chinese celery growth, so just make illumination in the frame, temperature, humidity, the more approaching suitable Chinese celery growing environment condition of weather conditions such as air permeability, make that leaf and the cane growth of Chinese celery are controlled, cane is partly increased, improved the color and luster of javan waterdropwort stem and leaf, controlled crude fiber content in the cane effectively, strengthened the tender and crisp property of Chinese celery, improved the quality and yield of Chinese celery, made the commodity rate of Chinese celery near the level in winter.
