Fertilizer special for raising rice seedlings

Abstract

A special fertilizer for nursing the seedlings of paddy rice and vegetables is prepared from ammonium phosphate, ammonium sulfate, potassium sulfate, zinc sulfate, fenaminosulf, thiobencarb, and adsorbent through proportional mixing. It contains N (10-14%), P2O5 (14-18%), K2O (3-5%), and ZnO (0.5-1.5%). Its advantages are high effect on making seedings robust, herbiciding and increasing yield, and low cost.

Description

technical field [0001] The invention relates to the field of mixed fertilizers, in particular to a seedling-raising special fertilizer used as seedbed base fertilizer or when preparing nutrient soil for rice seedling raising and vegetable seedling raising. Background technique [0002] Farmers commonly suffer from lack or excess of essential plant nutrients in the cultivation of rice and vegetable seedlings, especially severe disease and weed damage, resulting in insufficient seedlings, a large number of dead seedlings and reduced production after transplanting. At present, many products on the market are developed to address the above problems, such as the "Transplanting Spirit" launched by Beijing Zhizailing Technology Co., Ltd., and the "Special Fertilizer for Seedlings" developed by the Institute of Crop Nutrition Technology of the Heilongjiang Academy of Agricultural Sciences, etc. , but such similar products more or less have the following defects: [0003] 1. There i...

Problems solved by technology

[0005] 2. The above-mentioned similar products are mixed with N, P, K plus certain trace elements, fungicides, rooting powder and other growth conditioners, which cannot solve the problem of weed damage at the seedling stage

[0006] 3. The soil in Northwest China generally lacks the trace element - zinc, but some of the above-mentioned similar products blindly increase the phosphorus fertilizer, which leads to the imbalance of phosphorus and zinc in the soil, inhibits the absorption of zinc by the seedlings, and causes the algae plants in the rice field A large number of reproduction, affecting the normal growth of seedlings
