specific Embodiment approach 1

[0026] Specific implementation mode one: a kind of construction method of the acid rice seedling-raising soil that is rich in artificial humus in this embodiment is specifically completed according to the following steps:

[0027] 1. Prepare the soil mixture:

[0028] Mix the biomass material powder with the barrier soil, then add active additives and distilled water, and stir evenly to obtain a soil mixture;

[0029] The mass ratio of biomass material powder, barrier soil, active additive and distilled water described in step 1 is (10~30):(8~100):(1~4):(150~400);

[0030] 2. Preparation of humified soil:

[0031] ①. Put the soil mixture in a high-temperature and high-pressure hydrothermal reaction kettle, then raise the temperature of the high-temperature and high-pressure hydrothermal reaction kettle to 180°C to 220°C, and water under the conditions of a temperature of 180°C to 220°C and a pressure of 0.8MPa to 2.5MPa. Thermal reaction for 20h-28h to obtain the reaction pr...

specific Embodiment approach 2

[0034] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the particle size of the biomass material powder described in step 1 is 50 mesh to 200 mesh, and it is specifically prepared according to the following steps: first, the biomass material powder Cleaning is performed to remove impurities on the surface of the biomass material, and then drying at 60° C. to 80° C. for 10 hours to 24 hours, and finally the dried biomass material is pulverized to obtain biomass material powder. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0035] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the biomass material is one or several of rice straw, corn straw, soybean straw, rice husk, leaves and sawdust. mixture of species. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a construction method of rice seedling raising soil, in particular to a construction method of acidic rice seedling raising soil rich in artificial humus. The invention aims to solve the problems that soil resources are in shortage, high-quality soil is needed for rice seedling raising and transplanting, and the ecological environment of the soil gradually deteriorates. The method comprises the steps of 1, preparing a soil mixture; 2, humified soil is prepared; 3, mixing the humified soil with the raw material soil according to a certain proportion to obtain mixed soil, and culturing the mixed soil to obtain the acidic rice seedling raising soil rich in artificial humus. The preparation method is simple and convenient, and raw materials are cheap and easy to obtain, so that the method is suitable for large-scale synthesis preparation; the prepared acidic rice seedling raising soil rich in artificial humus is used for improving the water binding capacity of the soil and the absorption capacity of the soil on nutrient elements, and has a good seedling raising effect. According to the invention, the acidic rice seedling raising soil rich in artificial humus can be obtained.

Description

technical field [0001] The invention relates to a method for constructing rice seedling raising soil. Background technique [0002] Rice is one of the most important food crops in my country and the basic guarantee for survival. The unique climate characteristics and soil moisture in Northeast China provide unique natural conditions for it to become an important rice planting base in my country. In order to ensure that the seedlings have a sufficient growth period, seedling raising and transplanting are generally adopted in my country. Therefore, seedling raising has become a necessary link in the transplanting production process. High-quality soil is the basis for cultivating high-quality rice seedlings. At present, the nutrient soil used for seedling cultivation in Northeast my country is often taken from the soil of the plow layer in the black soil area. Problems such as soil diseases occur. At the same time, my country's soil ecological environment is deteriorating day...
