Substrate for transplanting and raising seedlings by Shibuya machine and its manufacturing method

Abstract

A shriveled grain machine transplanting seedling-raising substrate is a mixture composed of primary shriveled grain substrates and auxiliary materials; the primary shriveled grain substrate is a mixture composed of decomposed shriveled grains, peat soil and soil, and the ratio of each component in the mixture is expressed by volume The number of parts is calculated as: 3 to 5 parts of decomposed Shibaku, 1 to 2 parts of peat soil, and 2 to 3 parts of soil; the auxiliary material is ammonium sulfate or 120g / L iron sulfide aqueous solution or quicklime; the decomposed Shibaku is The substance made by fermenting and decomposing the mixture of Shibuya raw material, quicklime and yeast; the bulk density of the Shibuya machine transplanting seedling raising substrate is 0.65-0.85g / cm3, and its pH value is 7.0-7.5. The Shibuya machine seedling-raising substrate utilizes local raw materials, has low cost and good quality. The invention also provides a manufacturing method of the Shibuya machine-transplanting seedling substrate. The manufacturing method has the characteristics of simple operation, safety and environmental protection, and easy scale production. Promote and apply in Guangxi and other South China regions.

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...

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
