Problems solved by technology

The national conditions of our country with more people and less land determine that we must continue to increase the road of grain yield. Healthy and high-fertility soil is the prerequisite for increasing grain yield. At present, there are about 30% of low-yield soil in my country. Due to the existence of soil barrier factors, nutrient supply Imbalance, low water and fertilizer efficiency, and low and unstable crop yields have seriously affected the potential of light and temperature, and have become bottleneck factors for grain production to reach a new level

Embodiment 1

[0015] A method for fertilizing and preserving fertilizer for soil in alpine mountainous areas, characterized in that it comprises the following aspects:

[0016] (1) Detect the organic matter, fertility, soil texture, structure, etc. of the soil before planting;

[0017] (2) Reasonable rest and crop rotation, cultivate soil fertility, adopt dormancy and crop rotation methods for soil with poor organic matter and fertility, plant soybeans in spring, and after harvest in autumn, turn the soil in the sun for a week, then burn dried bean straw, bean leaves and other miscellaneous materials with soil cover. Grass, smoked soil to fertilize and kill insects. After a week, level the soil and plant safflower grass. In the spring of the second year, when the safflower grass is in full swing, turn the soil to store water and retting, and use it as base fertilizer for transplanting seedlings, because these crops belong to the leguminous family. , Rhizobium has a strong ability to fix nit...

Abstract

The invention discloses a method for cultivating and maintaining fertility of soil in cold highland rural areas. The method includes: detecting organic matters, fertility, texture and structure of the soil before planting, reasonably performing crop fallow and crop rotation, cultivating fertility of the soil, constructing a farmyard manure decomposing tank, collecting and accumulating a great quantity of farmyard manure and green manure and then after the farmyard manure and the like is sufficiently decomposed, fertilizing seedlings in time and enabling the seedlings to grow strong, reasonably cultivating and improving soil, accelerating soil ripening, generally ploughing the soil by 50-60cm and applying organic fertilizer. By the method for cultivating and maintaining fertility of the soil in cold highland rural areas, activity of soil microbes is promoted, the soil structure is improved, soil ripening is accelerated, and soil organic fertility is enhanced. Besides, the method is quite suitable for hardened fields in the rural areas, and acre yield of planting is greatly increased.

Description

technical field [0001] The invention mainly relates to a method for cultivating and preserving fertilizer, in particular to a method for cultivating and preserving fertilizer for soil in alpine mountainous areas. Background technique [0002] The food issue will dominate the trend of China's agricultural development and the orientation of agricultural policies for a long time to come, and it is also a key aspect that must be considered for the sustainable development of China's agriculture. Ensuring food security is the eternal theme of my country's sustainable agricultural development. The national conditions of our country with more people and less land determine that we must continue to increase the road of grain yield. Healthy and high-fertility soil is the prerequisite for increasing grain yield. At present, there are about 30% of low-yield soil in my country. Due to the existence of soil barrier factors, nutrient supply Imbalance, low water and fertilizer efficiency...
