At present, the shed enters the leisure period, which can strengthen management, improve soil performance, and prepare for the cultivation of the squat crop.
The plant residues after harvesting in time are clearing the hiding places of germs and pests. Therefore, after the production of vegetables, the vegetables should be promptly removed, and the fallen leaves, weeds, slings and covered mulch should be cleaned and transported outside the shed, away from the solar greenhouse, and the soil will be free from pollution. After the ground is cleaned, it will be sun-dried by 30 to 40 cm.
After the site has been cleared, a comprehensive disinfection should be carried out in the shed. The disinfection of the greenhouse is generally carried out by the sulfur fumigation method or by using a 45% chlorothalonil smoky greenhouse or a 30% keeling smoke. Closed shed, high temperature shack.
After several years of continuous use of the improved soil solar greenhouse, the problem of secondary salinization of the soil is serious, and it is necessary to try to improve the soil during summer leisure. 1. Apply fermented straw fertilizer and organic fertilizer. 2. Use 20 kg of corn flour per acre, add 1.2 to 2 kg of brown sugar and water to form a paste, carry out high-temperature fermentation for 10 days, add biological fertilizer with water, the effect is very good. 3. Use a sunshade net or crop vines to cool at the top of the greenhouse, and use a sprinkler method to cool the salt.
