Sowing of adzuki bean
Sowing at the right time is beneficial to Miao Qi, Miao Zhuang, multi-flowering and multi-pod, mature at the right time, and improve yield and quality. In order to ensure early emergence and full emergence of seedlings, the sowing depth should be consistent as far as possible. Before sowing, seeds should be selected mechanically or manually. Remove moth-eaten particles, broken particles and impurities to ensure the purity and purity of seeds. Seed drying 1-2d after seed selection can improve the viability of adzuki bean seeds.
You can also choose seed coating agent to dress seeds, control plant diseases and insect pests at seedling stage, and supplement trace elements. In the southern part of Heilongjiang Province, sowing is generally carried out from late April to mid-May, and in the cold northern part, sowing is generally carried out from May 5 to May 15. Suppress in time after sowing to avoid soil moisture loss. Drought areas can also be suppressed before and after sowing 1 time.
According to the natural conditions and production conditions, the planting density should be properly adjusted, and the seedlings should be protected in high-fertilizer land150,000-225,000 plants/hm2, in medium-fertilizer land, 225,000-303,000 plants/hm2, and in low-fertilizer land, more than 300,000 plants/hm2. The line spacing is generally 50-60cm. When the emergence rate reaches 80%, the investigation shall be carried out, and if it is found that there is a lack of seedlings, the germination shall be accelerated and replanted in time.
