How to deal with the damage of seedlings in greenhouses
Farmers in Xinhe Town, Hanchuan City asked: Last year, due to the poor performance of cotton, we changed some of the cotton land to grow vegetables in greenhouses. However, it was found that some of the vegetable seedlings in the greenhouse exhibited wilting and wilting; some transplanted melon seedlings were not stiff; some seedlings of transplanted melons showed burning seedlings when the temperature rose. How is this going? what should I do? The reason is that due to improper fertilization, there is a large amount of ammonia-induced accidents in the greenhouse. Prevention and control methods First, we must regularly test greenhouse ammonia. Large planting households should always check the gas status inside the shed. You can use the test paper sold by the pharmaceutical company to measure the pH value of the water droplets in the shed. When the PH value is above 8.2, you must exhaust the air in time. Second, rescue the damaged seedlings. When the vegetables in the shed have developed symptoms of ammonia poisoning, besides the ventilation, one should quickly irrigate and reduce the concentration of the soil solution; the second is to use phlegm-retention or tianfusu 0.01% EC 10 oz 30 kg Third, spraying Huimanfeng or Zhuang Fuxing and other active liquid fertilizers, the concentration of 1:500 times the liquid, can better balance the pH of the plant body and the soil; four can be sprayed on the back of plant leaves 1% vinegar, can reduce and ease harm. Third, scientific fertilization. First, the application of organic fertilizer as a base fertilizer must be fully decomposed; Second, fertilization must be deep-seated ditch, can not be simple, for the provincial laborers to spread; Third, the fertilization can not be excessive, especially the fertilizer should be a small number of times; four is appropriate After fertilization or irrigation, the fertilizer can be released and released in time.
