Method for efficiently making rice seedling soil and using device of method

Abstract

The invention relates to the technical field of seedling soil preparation, in particular to a method for efficiently preparing rice seedling soil and a using device of the method. The method comprisesthe following steps: (1) selecting a seedling soil collection point; (2) preliminary crushing of soil: performing rotary tillage on a farmland where the seedling soil collection point is located, wherein the rotary tillage time is before the winter of the last year, and exposing soil blocks to the field for self-thawing and de-freezing after rotary tillage; (3) collection of soil: after the temperature rises back in the first ten days of March, transferring soil into an indoor warehouse when the water content of the soil is less than or equal to 25% after the farmland where the seedling soilcollecting point is irradiated by the sunlight for one week; (4) adjustment of the pH value: mixing soil and a rice seedling raising substrate in proportion, and adjusting the pH value of the soil tobe greater than or equal to 4.5 and less than or equal to 5.5; (5) crushing of the soil: crushing the soil until the diameter is less than 0.5 cm; and (6) storage of seedling soil. The method has theadvantages of high preparation efficiency, full-process mechanical operation, labor saving and effort saving; the quality of the seedling soil is high, the diameter of seedling soil particles convenient to control, the pH value of the seedling soil is controlled accurately, and the influence of weather factors is small.

Description

technical field [0001] The invention relates to the technical field of making seedling soil, in particular to a method for efficiently making rice seedling soil and a device for using the same. Background technique [0002] The technical scheme of existing making seedling soil is as follows: [0003] a) Select the appropriate seedling soil collection point. [0004] b) Rotary tiller to till the soil twice, loosen the soil, and expose it to the sun for about a week. The first round of rotary tillage is before winter. After the end of rotary tillage, the soil blocks are exposed in the field, and let them go through the process of winter freezing and spring thawing. The soil blocks become soft. In the middle and late March of the second year, the second time Rotary tillage (about 5 days of light is required before the second rotary tillage), and the second rotary tillage is to further crush the soil and facilitate soil sieving. [0005] c) Use a sieve to screen out the soil ...

AI Technical Summary

Problems solved by technology

[0008] The objective shortcomings of the existing seedling soil production technology mainly include: easily affected by weather factors, low efficiency, difficult to control the diameter and pH value of the seedling soil accurately, and uneven mixing of soil and seedling soil, which is not conducive to large-scale seedling raising work.

①Soil crushing and seedling soil mixing are carried out in the open air. In case of rainy weather and the soil is damp, it is impossible to sieve the soil and mix the seedling soil. If the soil is severely damp, it cannot be used for mechanical seeding at all. will greatly affect the work progress

②Most links in the seedling soil production process are manual operations, and the operation efficiency is low

③ The degree of mechanization in each link of seedling soil production is low, and it is difficult to accurately control the particle size of seedling soil and the pH value of seedling soil

④Because the whole operation process is time-consuming, it is not conducive to the normal development of subsequent mechanical seeding work
