A method for planting chives and its special astigmatism cooling heat radiation control film

Abstract

The invention provides a planting method for hotbed chives and a light-diffusing, cooling and heat-radiation regulation and control film specially used for the planting method. The planting method comprises a film lamination step, wherein in the film lamination step, the temperature is controlled to 20-15 DEG C, after the light-diffusing, cooling and heat-radiation regulation and control film is laminated, one ventilating hole is formed on one side of a vegetable bed every 1.5m, and a U-shaped ventilating pipe is arranged in each ventilating hole; the light-diffusing, cooling and heat-radiation regulation and control film has sunlight shielding rate of 99% and thickness of 120 mum. The planting method also comprises a field planting and transplanting step, wherein in the field planting and transplanting step, the hotbed chive planting density is 60000 / mu, and the planting row distance is 20cm. By adopting the planting method, the quality of hotbed chives in summer is obviously improved, the nutrient content is high, the yield is high and the occurrence rate of diseases and insect pests is low.

Description

technical field [0001] The invention relates to a chive planting method and a special astigmatism cooling heat radiation regulating film, belonging to the field of agricultural technology. Background technique [0002] Leek (A. tuberosum Rottl. ex Spreng.) is a perennial root plant of the genus Allium tuberosum in the family Liliaceae. [0003] Chives are native to China and are also cultivated in East Asian countries. Very popular with the masses, the cultivation area of ​​Shandong chives has reached 500,000 mu. [0004] Different cultivation methods show different forms. The leeks grown in the sun grow thickly and are green in color. They are usually called leeks. The leeks grown in the dark environment are isolated from light and grow completely in the dark. Because there is no sunlight supply, If it cannot carry out photosynthesis and synthesize chlorophyll, it will turn yellow, which is called "chives", which is the product of leeks that have been softened and turned ...

AI Technical Summary

Problems solved by technology

[0006] The production of chives in the prior art has the following defects: first, the quality of chives is poor; second, the yield of chives is not high; third, 1-2 stubbles of chives are cultivated every year, and annual supply cannot be realized; fourth, the ambient temperature inside the shed Unable to stabilize, affecting the production of Chinese chives; Fifth, the incidence of pests and diseases during the production of Chinese chives is high
