Method for preparing special soil-insect-killing base fertilizers and supplementary fertilizers for solanaceous vegetables

Abstract

The invention belongs to the field of fertilizers for solanaceous vegetables, and relates to a method for preparing special soil-insect-killing base fertilizers and supplementary fertilizers for solanaceous vegetables. In the prior art, common fertilizers are used as the base fertilizers and the supplementary fertilizers. The preparation method comprises the following steps: selecting 950 parts by weight of cabo and 50 parts by weight of air-dried Rhododendron molle; crushing, mixing, piling to ferment for 7-15 days, and taking out for air drying; adding nitrogen-phosphorus-potassium raw fertilizers to obtain the special base fertilizers for solanaceous vegetables of which the organic matter content is 5% and the N-P2O5-K2O-Ca content is 13-14-20-2; and adding nitrogen-phosphorus-potassium raw fertilizers to obtain the special supplementary fertilizers for solanaceous vegetables of which the organic matter content is 5% and the N-P2O5-K2O-Ca content is 17-8-20-2. The invention has the following advantages: both the base fertilizers and the supplementary fertilizers are special fertilizers, and can be used conveniently; the special fertilizers conform to fertilization characteristics of solanaceous vegetables, and meet the requirements of fertilizers for vegetables having long flowering seasons and fruiting seasons; by using the special fertilizers, the solanaceous vegetables are good in quality and high in yield; and soil insects in the growing season can be effectively killed.

Description

technical field [0001] The invention belongs to a fertilizer for solanaceous vegetables, in particular to a special base fertilizer and a topdressing method for killing underground pests for solanaceous vegetables. Background technique [0002] Solanaceous vegetables include tomatoes, eggplants, and peppers, which are people's favorite vegetables that are often eaten. The common feature of solanaceous vegetables is budding, flowering and fruiting at the same time, long flowering and fruiting time, and high yield. In the prior art, general-purpose fertilizers are used as base fertilizer and topdressing fertilizer for solanaceous vegetables, such as compound fertilizers with NPK 15-15-15; or fertilizers such as urea, diammonium phosphate, and potassium sulfate are applied separately. Even if some special fertilizers for vegetables are used, the base fertilizer and top dressing are not designed according to the characteristics of fertilizer requirements in different growth sta...

AI Technical Summary

Problems solved by technology

Even if some special fertilizers for vegetables are used, the base fertilizer and top dressing are not designed according to the characteristics of fertilizer requirements in different growth stages of solanaceous vegetables, which cannot meet the fertilizer needs of solanaceous vegetables during the growth period, resulting in the quality and output of solanaceous vegetables. The most ideal level, can not get the best economic benefits

At the same time, due to the long growth cycle of solanaceous vegetables, in the prior art, pesticides for killing underground pests are applied at one time before sowing of solanaceous vegetables. , The harvested fruit contains residual pesticides, which affects people's safe consumption
