Planting skills of vegetables in Autumn

The cultivation of vegetables is generally divided into summer and autumn, and the planting skills and points for attention of vegetables in different seasons are also different. below, the author will share the planting skills of autumn vegetables with you.

1. Variety selection: the early stage of autumn sowing vegetables is high temperature and rainy, and the later growth stage coincides with low temperature and drought. Therefore, carrots, water radish, Chinese cabbage, bean, cabbage and other vegetables sown in autumn should choose varieties with wide adaptability, cold tolerance, disease resistance and high yield. Carrots can choose Japanese black field five inch ginseng, seven inch ginseng, small top red, whip pole red; water radish can choose Dahongpao, Lu Luobu No. 1, Lu radish No. 3, Lu radish No. 6, Jiujinghong; Chinese cabbage can choose Beijing New No. 1, Beijing Youkang No. 3, Lu Bai No. 2, Tianjin Qingma Leaf, Fengkang 70; kidney beans can choose Green Dragon, Nine grains White, Old Laoyao and other varieties to cultivate.

2. Sowing time: carrots were planted before and after "Greater Heat", and radish and Chinese cabbage were planted before and after "the Beginning of Autumn". The phenomenon of falling flowers and pods will occur when sowing beans too early, and the yield will be low if sowing too late. When sowing, it can be broadcast live between "Lesser Heat" and "the Beginning of Autumn". 3. Pay attention to drainage and waterlogging prevention: autumn sowing vegetables are prone to rainy weather at seedling stage, so attention should be paid to drainage and waterlogging prevention at autumn sowing stage, and high bed or high ridge cultivation can be used during soil preparation.

4. prevention and control of diseases and insect pests: the seedling stage of autumn-sown vegetables is at the peak of the occurrence of Plutella xylostella, Helicoverpa armigera and brown spot. High-efficient and low-toxic pollution-free pesticides such as Yitaibao, Lucaibao and high-chlorine horse spray can be used to control insect pests. The disease can be controlled by mixed spray of agricultural streptomycin, frost blight like, DuPont Kelu and so on, usually once every 10 days, 2 times and 3 times, and stop using medicine 7 days and 10 days before harvest.

Points for attention

Select the suitable cultivated varieties: the temperature is high in the early stage of raising seedlings, the moisture changes greatly, and the late growth stage is in the stage of low temperature and low light, so the cultivated varieties with wide adaptability, disease resistance, cold tolerance and high yield should be selected.

Prevent the harm caused by high temperature and rainstorm at seedling stage: high temperature and rainstorm will inhibit the growth of vegetables at seedling stage, resulting in frequent occurrence of diseases and insect pests. When raising seedlings, the application of sunshade net and anti-insect net can effectively prevent the erosion of high temperature, rainstorm and diseases and insect pests.
