Problems solved by technology

[0002] Since the rice seedling strengthening agent came out in the early 1980s, it has been widely used in rice seedling raising. It not only solves the morbid problems such as rotten seedlings and black roots that are prone to occur in the process of rice seedling raising, but also has the effect of strengthening seedlings. The rice seedling strengthening agent produced has roughly the same composition. As sulfuric acid as the carrier, the useful fly ash is used, and the crushed exhausted coal is added with peat and furfural residue. The basic effects are the same. The existing seedling strengthening agent has problems in the use process : 1. Low nutrient utilization rate 2. The effect of promoting seed germination and emergence is not obvious enough

Abstract

A chemical agent for culturing strong rice seedlings in saline-alkaline field is prepared from the clinoptilolite powder through roll-type calcinig while filling oxygen at 80-300 deg.C for 1.5-2 hr, and proportionally adding sulfuric acid, ammonium sulfate, diammonium phosphate, potassium sulfate, zinc sulfate, trace elements, fenaminosulf and metalaxyl.

Description

technical field [0001] The invention belongs to the technical field of agricultural rice seedling raising. Background technique [0002] Since its advent in the early 1980s, the rice seedling strengthening agent has been widely used in rice seedling raising. It not only solves the morbid problems such as rotten seedlings and black roots that are easy to occur in the process of rice seedling raising, but also has the effect of strengthening seedlings. The ingredients of the rice seedling strengthening agent produced are basically the same. The basic effects of using fly ash as a carrier of sulfuric acid and pulverized coal and furfural residue are the same. The existing seedling strengthening agent has problems in the use process. : 1. The nutrient utilization rate is low. 2. The promoting effect on seed germination and emergence is not obvious enough. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above-mentioned shortcomings. It us...
