Abstract
A preparation method of a rice disease-resistant seedling-cultivation substrate includes the following steps of firstly, taking field soil and rice straw as the main raw materials, smashing field soil, and continuously drying smashed field soil at a temperature of 85-95 DEG C for 10-14 minutes; secondly, collecting harvested rice straw, cutting the straw into segments 2-3 cm long, and spraying water on the cut straw segments according to the rule that 1.5-1.8 kg of water is sprayed on every 10 kg of rice straw; thirdly, sending the wet rice straw segments into a tumbling machine to be tumbled, and vacuumizing once every 9-10 minutes during tumbling; fourthly, sending the tumbled rice straw into a drying device to be continuously dried for 30-50 minutes at a temperature of 45-55 DEG C; fifthly, smashing the dried rice straw to prepare straw meal, mixing the straw meal with field soil in the first step according to the weight ratio of 1:(3-5), screening the mixture by means of a screen of 80-100 meshes, and putting mixed powder into a stainless steel container, adding water for dilution, pumping the material into a centrifugal type spray drying tower to be dried, and granulating the dried material to obtain the rice seedling-cultivation substrate.
Description
Technical field
The present invention relates to technical field of fertilizers, be specifically related to the compound method of a kind of paddy disease-resistant seedling medium.
Background technology
From the eighties in last century, rice shoot with rsgun and wide planting cultivation technique is by introducing, test, demonstrating in China
Large scale application, the most history of 30 years, make China's Rice Production have from live cultivation
Training is to the leap of rice seedling on upland field rice transplanting cultivation, and Rice Production is able to swift and violent development, presents today gratifying
Situation, cultivated area is big, unit yield is high, and total producing is sure to occupy first of grain yield, remarkable in economical benefits.
The essence of dry seedling bed of rice thin planting transplantation technique is: use fertile loose upland field soil, in seedbed
In the environment of arid, cultivating root system stalwartness flourishing, the short and thick pier of stem and leaf is real, with the rice shoot of low position tiller,
After being transplanted to paddy field environment, outburst is taken root, and quickly turns green, spaced far plant, illumination is sufficient, ventilates
Good condition is early sent out tiller, many tillers, relies on the most effective tiller spike number, it is achieved stable high yield,
Center highlights the production-increasing function of high-quality rice shoot.
Its basic core technology is from the beginning of seedling bed earth, and seedling bed earth is commonly called as Nutrition Soil or nursery soil, skill
Art requires that the farm manure by rotten heat, the peat composed of rotten mosses, fertile dry land soil press 3:3:4 configuration.When just rising rice seedling on upland field
Rural area is made by technology requirement, and the seedling quality cultivated is fine, turns green fast, and tiller is many, and yield is high,
Anosis without calamity, peasant is that firsthand experience arrives, but till now, will take loose fertile dry land topsoil
Table soil, the farm manure become thoroughly decomposed and the peat composed of rotten mosses are part very tall orders, and livestock and poultry cultivation is few, can dig the low of the peat composed of rotten mosses
Hollow overbank, grassy marshland, Cao Tangdou are developed into paddy field, have the dry land of water condition mostly the most all to make water into
Field, the annual nursery of per hectare needs 2m3Nursery soil, excavating, at all of dike in region, paddy field for years
Anti-, the resource leaving uncultivated ground has adopted exhaustion, knows obviously that present nursery soil far deviate from drought and educates technical purpose,
Really having no idea, present nursery is regardless of black earth, or loess, roadbed side, under ditch, only
To be done can be screened into fine earth, is just used for making seedling bed earth, unfertilized chemical fertilizer is made up a deficiency, nursery soil property
Barren, harden, cold slurry, the very thin few root of the rice shoot that brings out, in spite of illness, after rice transplanting, survival rate is low in excessive growth,
Turn green slow, tiller in evening, do not realize stable high yield with high-quality rice shoot, but yield is pressed in
On chemical fertilizer and weather, the time is good, and yield can maintain, and slightly meets disaster rice agriculture and suffers untold misery, if running into the spring
In the flood time, being water everywhere, adopt soil nowhere, agricultural production is felt simply helpless, and misses the farming season.
Summary of the invention
The technical problem to be solved is to provide a kind of nutrient content high, resourceful Oryza sativa L.
The compound method of disease-resistant seedling medium.
The technical problem to be solved realizes by the following technical solutions:
The compound method of a kind of paddy disease-resistant seedling medium, specifically comprises the following steps that
(1) take field soil with rice straw as primary raw material, field soil is pulverized, the temperature of 85-95 DEG C
Under continuous drying 10-14 minute, field soil is sterilized, also makes field soil hardening simultaneously；
(2) collect harvested rice straw, be then cut into the section of 2-3 centimeter length, to the straw cut
Duan Jinhang water spray processes, and according to every 10kg rice straw water spray 1.5-1.8kg, makes straw moisten, increases straw
The water content of stalk；
(3) by under moisture state rice straw section send into tumbler carry out tumbling process, during tumbling every
9-10 minute evacuation once, exhausts tumbling 15 minutes, then vacuum pumping after vacuum every time, so circulates 5
Secondary；Make straw can reach to breathe the effect of massage in tumbling procedure, make straw soften, in improving
The utilization rate of portion's effective ingredient；
(4) rice straw after tumbling is sent into drying equipment, continuous drying at a temperature of 45-55 DEG C
30-50 minute, make straw surface moisture evaporate, straw is carried out cold drying, prevent high temperature in straw
The destruction of organic principle；
(5) rice straw after dried is pulverized, prepare powder of straw, by powder of straw and step
(1) the field soil in mixes by weight 1:3-5, then crosses 80-100 mesh sieve, then by mixed powder
Putting in rustless steel container, dilute, the addition of water is 1.5--3 times of stalk powder weight, even
Continuous stirring about 30 minutes, then pump into Centrafugal spray drying tower, use Centrafugal spray drying tower to carry out
It is spray-dried, then dried object is carried out pelletize, obtain rice nursery substrate.This stromatolysis is good, supports
Divide and can quickly discharge, absorb for rice seedling, the problem solving seedling cultivation of rice trace element disappearance, with
Time raw material be easy to get, can industrialized production.
The invention has the beneficial effects as follows: it is characteristic of the invention that can be not only that rice seedling provides sufficient having
Machine nutrient, instant capacity is good, and nutrients release is fast, stimulates and promotes paddy growth, can increase having of substrate kind
Machine nitrogen content, promotes phosphorus, the potassium activity in soil and effectiveness, plays its fixed nitrogen, phosphorus decomposing, potassium decomposing
Effect.Applying seedling of the present invention, rice shoot root system bar number is many, root hair is many, root volume big, and seedling stage does not occur
Disease, seedling packing is good, turns green and does not delay Seedling, directly take root and survive, start effective tillering in advance after rice transplanting,
Increasing both production and income can be realized.
