Organic matrix seedling raising method for mechanically-planted paddy formula

Abstract

The invention discloses an organic matrix seedling raising method for a mechanically-planted paddy formula. The method comprises the following steps: selecting a seedbed and materials; seeding and raising seedlings; performing seedling-stage management including temperature management, fertilizer management, illumination management, chemical control, pest control, fertilizer dressing and seedling pulling and conveying. According to the method, a farmland or yard with high topography, ventilation, light transmission and convenience for water irrigation and drainage is taken as the seedbed, strong seedlings which conform to mechanical planting requirements are cultured, the seedling raising land is saved, the seedling raising labor strength is alleviated, and water resources are saved. Rice chaff charcoal and Chaohu lake algae peat soil which are prepared at a mass ratio of 6:4 are taken as mother soil, and 0.5% of thoroughly-decomposed organic bacterial manure, 0.1% of urea, 0.1% of potassium dihydrogen phosphate and 0.1% of seedling strengthening agent are added so as to prepare an organic matrix which is used for supplying sufficient nutritional ingredients for the seedlings, so that the cost is lowered.

Description

Technical field [0001] The invention belongs to the technical field of rice planting, in particular to a method for raising seedlings in a machine-transplanted rice formula organic substrate. Background technique [0002] With the popularization of rice mechanical transplantation technology, it is the key to cultivate strong seedlings that meet the mechanical transplantation requirements. At present, the traditional method of raising seedlings in the field not only requires a suitable seedling field, but also wastes a lot of manpower and material resources. Machine-transplanted rice seedling raising is a key link in the high-yield cultivation technology system of machine-transplanted rice. Compared with conventional seedling raising methods, machine-transplanted rice seedling raising is characterized by high seeding density and high standardization requirements. [0003] Most of the machine-transplanted rice seedlings in the prior art are mainly chemical fertilizers, which are eas...

AI Technical Summary

Problems solved by technology

[0003] Most of the machine-transplanted rice seedlings in the prior art are mainly chemical fertilizers, which can easily cause soil compaction and soil erosion, and the roots of the cultivated seedlings are not strong enough, which affects the overall quality of the seedlings, thereby affecting the rice planting industry.
