How to apply biological fertilizer skillfully
First, the combination of organic fertilizer and inorganic fertilizer many vegetable farmers, whether flushing or topdressing, are mainly chemical fertilizer. Although some flushing fertilizers contain humic acid, inorganic fertilizers are mainly ammonium nitrate, urea and other nitrogen fertilizers. Vegetables grow well in the short term, but they lack long-term effects, so they should be combined with organic fertilizers.
Second, with the combination of topdressing and flushing fertilization, the fertilizer is mainly multi-component compound fertilizer, and the combination of topdressing and flushing application is adopted to solve the problem of fertilizer demand of surface roots on the one hand, and on the other hand, topdressing can activate the soil layer, increase roots and alleviate fertilizer efficiency.
Third, the combination of big water and small water application, many vegetable farmers apply fertilizer with big water in both seedling stage and fruiting stage, which makes the fertilizer and water too large, causing seedling disease, root rot and root retting. Small water is easy to dry up, no matter biological fertilizer, organic fertilizer, chemical fertilizer depends on seedling fertilizer, reasonable amount.
Fourth, the combination of biological fertilizer and chemical fertilizer Beshikang microbial organic fertilizer is rich in more than a dozen kinds of beneficial bacteria, which can activate soil and regulate nutrients. Combined application with inorganic fertilizer can relieve fertilizer damage, increase soil organic matter and promote root development.
