Shrivelled kernel mechanical transplanting seedling raising substrate and preparation method of shrivelled kernel mechanical transplanting seedling raising substrate

Abstract

The invention relates to a shrivelled kernel mechanical transplanting seedling raising substrate, which is a mixture formed by a primary shrivelled kernel substrate and an auxiliary material, wherein the primary shrivelled kernel substrate is a mixture formed by the following ingredients in parts by volume: 3 to 5 parts of rotten shrivelled kernel, 1 to 2 parts of peaty soil and 2 to 3 parts of soil; the auxiliary material is ammonium sulfate, or 120g / L ferric sulfide water solution or quicklime; the rotten shrivelled kernel is a substance formed by the mixture of shrivelled kernel raw materials, quicklime and saccharomycetes through fermentation rotting; the volume weight of the shrivelled kernel mechanical transplanting seedling raising substrate is 0.65 to 0.85g / cm<3>, and the PH value is 7.0 to 7.5. The shrivelled kernel mechanical transplanting seedling raising substrate has the advantages that local raw materials are used; the cost is low; the quality is good. Meanwhile, the invention also provides a preparation method of the shrivelled kernel mechanical transplanting seedling raising substrate. The preparation method has the characteristics that the operation is simple; safety is realized; the environment is protected; the mass production is easy, and the like. The preparation method can be conveniently popularized and applied to south China such as Guizhong.

Description

technical field [0001] The invention relates to the technical field of rice seedling raising, in particular to a seedling raising substrate for shrubbed rice machine transplanting and a manufacturing method thereof. Background technique [0002] At present, the whole mechanized production of rice has become a trend, and the rice machine transplanting technology is developing rapidly. However, there are still many problems in rice machine transplanting and seedling raising in Guizhong and other South China regions, which has become the bottleneck of the whole process of rice mechanized production. The main problem is the selection of rice machine transplanting seedling substrate. question: [0003] 1. Insufficiency of using local nutrient soil as seedling-raising substrate: [0004] (1) At present, in Liuzhou City and some areas in South China, rice machine-transplanted seedlings are mainly raised with nutrient soil, and the work intensity of soil extraction in the process o...

AI Technical Summary

Problems solved by technology

[0003] 1. Insufficiency of using local nutrient soil as seedling-raising substrate:

[0006] 1. The finished seedling substrates from Jiangsu, Shandong and other places (hereinafter referred to as finished substrates) have the following problems in the process of being transported to Liuzhou City for use: (1) Most of the finished substrates with good performance on the market are finished substrates from Jiangsu, Shandong and other places. It is 54-64 yuan per mu in Liuzhou City, and the large-scale use cost of seedling enterprises is too high, so they dare not use it in large quantities; (2) When used in Liuzhou City, due to the high temperature and high humidity, the seedling age is short (the seedling age in Liuzhou City is 15- 20 days, the time to go north is longer, Jiangsu is about 30 days), seedling raising shows that the total root system of the seedlings is insufficient, the root system is not well wrapped, it is difficult to form a blanket, and the seedlings are easily broken during transportation and on the rice transplanter. or even broken, which is not conducive to the development of transplanting operations; (3) the finished substrates in Jiangsu, Shandong and other places are too light in bulk density and low in viscosity. The enthusiasm of farmers to use rice transplanters, thus affecting the popularity and progress of mechanization in the whole process of rice production

[0007] 2. Insufficiency of using northern raw materials to prepare matrix in Guizhong South China: (1) At present, most matrix preparations in Guizhong South China need to add vermiculite and perlite, which must be purchased from the north; due to transportation costs, it is more expensive than using Jiangsu, Shandong, etc. The cost of the ground product matrix has been reduced by less than 15%; (2) Vermiculite and perlite contain very little nutrients, and some chemical fertilizers need to be added for mixing, which still has hidden dangers of burning buds and seedlings, and at the same time cannot alleviate the environmental impact of the use of chemical fertilizers. Pollution problem; (3) Vermiculite, perlite, etc. are non-renewable raw materials, and excessive use for a long time will inevitably cause adverse effects on the environment
