What should I pay attention to when planting mung bean in autumn? Autumn sowing mung bean planting attention

The problem of autumn sowing mung bean planting:

1. Choose good varieties. In different regions, it is required to have suitable varieties for planting in order to obtain high yield. Single crops and intercropping should also choose different varieties. Generally, early maturing varieties and erect cultivars should be closely planted, and semi-vine cultivars should be sparsely planted, with many branches and vines, which should be more rare when planted. Regardless of the single crop and the place where it is planted, it is necessary to choose a variety that is resistant to disease and high yield. For example, Anhui Mingguang Mung Bean, Zhonglv 2, Sulu 1 and other varieties are high-yield and disease-resistant varieties.

2, fine land preparation. Before the sowing, fine-tune the land in the dry land, so that the land is flat and loose, and then the hole is spotted. The autumn leisure field makes full use of the field sensation after the early rice harvesting, and takes the seedlings on the edge of the grassland to facilitate the emergence of seedlings.

3. Sowing at the right time. Autumn is in the high temperature and dry season. Therefore, it should be sown when robbing, generally in the end of July to early August sowing, so that the pods can mature before the frost, can avoid the effects of low temperature. The autumn sowing needs to be properly planted. Generally, the amount of the seed used is 1.5-2 kg, 3-4 grains per hole, and 9000-10000 plants per mu.

4, Miao Ding Miao. The cultivating and weeding should be timely, when the first piece of straight leaves is unfolded, and the second piece of compound leaves is not unfolded, the seedlings are fixed, and the weak leaves stay strong, and the mixed leaves are kept pure, and 2 plants are kept for each seedling to prevent the seedlings from clustering and competing for water. The resulting pods are small and small, affecting yield. Generally, cultivating 2-3 times, combined with cultivating for cultivating roots.

5. Rational fertilization. The cover seed fertilizer is generally mixed with fire ash, furnace ash, human waste, and phosphate fertilizer for 10-25 days. When planting, grab a gray cover seed for seedling fertilizer. Before and after the mung bean branching, 10-12.5 kg of urea is applied to the water; combined with cultivating and weeding, promoting seedling growth, cultivating strong seedlings, and increasing the number of branches and flower buds. Strong seed fertilizer is sprayed with 100-150 g of 0.4% potassium dihydrogen phosphate leaf when the mung bean is full of flowers, so as to protect the pods and improve the seed setting rate of the pods, which is beneficial to increase yield.

6, scientific irrigation. Mung bean is drought-tolerant, but it needs more water before and after flowering. If it is conditional, it can be used for irrigation, which can promote its growth and development, and increase the number of flowering and pods.

7, prevention of disease and pest control. Zhonglu 2 and other varieties have strong disease resistance. If improperly managed, leaf spot, root rot, blight and powdery mildew often occur. Spray 100g of 40% carbendazim suspension in water before the buds, or prevent it with thiophanate and anti-cyanine. Found that powdery mildew can be combined with the application of stone sulfur mixture control. For the control of leaf roller, leaf spider, aphid, etc., can be used for prevention and treatment.
