January Vegetable Farming Knows
First, energy-saving solar greenhouses (winter sheds) wintering hoe vegetables management. Since the beginning of winter this year, there have been many shades, rain, and foggy days. The light is weak, the temperature is low, and the air is moist, which has a great impact on various protected crops. The cucumber plants grow weakly, and most of the plants show heads, roots, dead borer, downy mildew, and diseases. Tomatoes, eggplants, and spicy (sweet) peppers have stem rot, disease, leaf mold, and gray mold. In addition, the result is that the fruit settling is slow. Therefore, in management, try to increase the temperature in the greenhouse, especially to improve the ground temperature. Open the mulch on sunny days, lighten the leeches properly, and tightly cover the mulch at about 2 pm, spraying the plants that grow weaker. It has a promoting effect. The quick absorption of Yunda-120+ methanal foliar fertilizer sprays Jinyun Da 120+ Tieda Ling (Yunda brand wolfberry state of iron element) to yellow-leaved plants, which can be combined with pesticides to spray and promote growth. . Second, disease prevention and control. Due to more rainy and foggy weather this year, the humidity in the shed is high, and it is easy to induce gray mold, leaf mold, epidemic disease, downy mildew, powdery mildew, etc. of the crops. It is not easy to spray liquid pesticides on prevention and control, and aerosol or dust should be used. , such as 45% chlorothalonil aerosol and 10% quick-inking aerosol, or 5% chlorothalonil dust, spray pesticides after sunny days, such as Anker, New Luling, Halic, Yunsheng, 100 Site and other 5 days to 7 days Shi once, to be used alternately with several pesticides, when spraying pesticides increase Jinyunda -120 can increase the permeability of pesticides, effectively improve the control effect. Third, sowing varieties. The watermelons, cucurbits, and cucumbers in the middle and small sheds should be raised in the greenhouse or in Yangshuo in early January. The varieties are: Watermelon Jingxin No.1, No.5, Big Black Crown, Zhengza No.5, No.9, and Xiongnong No.8; West Huhu has Jingying, Jinghu No.1 and No.3; Cucumber has Jinlu 1,5 number. In the late period, planting medium and small arched cabbage and tomatoes, before the planting, warm up 5 to 7 days in advance, until the temperature of 5 centimeters stabilizes at 10 or more, choose the sunny morning planting, and cover the grasshopper insulation to promote mild seedlings. Fourth, during the Spring Festival, we must increase production and management of greenhouses. For overwintering crops such as cucumbers, tomatoes, and spicy (sweet) peppers, which grow weaker, top dressing should be combined with watering. M. Diammonium or ternary compound fertilizer should be used for 20 kg. The greenhouse with insufficient basal fertilizer can be used in late January. The application of chicken manure in the ditch is 1000 kg to 1500 kg per mu, which is turned into the soil and watered in time to increase the yield in the later period. 5. For the plants of tomato groats, deformed fruit, lobular disease, and sika virus disease combined with sprayed pesticides, spray plant growth regulator Yunda-120 to + foliar zinc fertilizer, calcium daring, and the United States. Xerox regulates the growth of crops.
