Problems solved by technology

At present, there is no method to quickly improve the drought resistance of plants. Therefore, the induced resistance produced by an abiotic stress treatment can be used to improve the resistance of various plant varieties (especially some important agricultural and pastoral crops) to other abiotic stresses. It is of great significance to increase the yield of crops under drought conditions, maintain water and soil conservation capacity and improve the regional ecological environment

Embodiment 1

[0034] A method for improving rice drought resistance through low-salt induction treatment, the steps are as follows:

[0035] 1. Planting:

[0036] Generally, fertilize, deep plow (5-10 cm) and level off the seedling land first. Under normal circumstances, apply enough base fertilizer at a time, every 667m 2 Apply 2000 or 2400 or 2600 or 2800 or 3000Kg of decomposed organic fertilizer (including cow manure, sheep manure, rabbit manure, etc.), and add appropriate amount (40 or 50 or 60 kg per mu) of compound fertilizer (high concentration of potassium sulfate, containing nitrate Nitrogen, total nutrient not less than 45%), apply 65 or 70 or 75 kg of ammonium bicarbonate per mu. Carefully prepare the soil before planting, disinfect the soil with 3% (mass volume ratio) ferrous sulfate, use 0.4 or 0.5 or 0.6 kg of ferrous sulfate solution per square meter, make a seedbed (usually a flat bed), and level the bed surface. Rice seedlings are first cultivated in a certain field. Thi...

[0043] A method for low-salt induction treatment to improve drought resistance of alfalfa, the steps are as follows:

[0044] 1. Planting:

[0045] Generally, fertilize the seedling land first, plow it deeply (5 or 6 or 7 or 8 or 9 or 10 cm), and level it well. Generally, apply enough base fertilizer at one time, every 667m 2 Apply 2000 or 2400 or 2700 or 3000Kg of decomposed organic fertilizer (including cow manure, sheep manure, rabbit manure, etc.), and add appropriate amount (40 or 50 or 60 kg per mu) of compound fertilizer (high concentration potassium sulfate, containing nitrate nitrogen, The total nutrient is not less than 45%), and 65 or 70 or 75 kg of ammonium bicarbonate is applied per mu. Carefully prepare the soil before planting, disinfect the soil with 3% (mass volume ratio) ferrous sulfate, use 0.4 or 0.5 or 0.6 kg of ferrous sulfate solution per square meter, make a seedbed (usually a flat bed), and level the bed surface. Alfalfa seeds must be cleaned so that...

Embodiment 3

[0052] A method for improving bermudagrass drought resistance through low-salt induction treatment, the steps are as follows:

[0053] 1. Planting:

[0054] Generally, fertilize the seedling land first, plow it deeply (5 or 6 or 7 or 8 or 9 or 10 cm), and level it well. Generally, apply enough base fertilizer at one time, every 667m 2 Apply 2000 or 2200 or 2600 or 2800 or 3000Kg of decomposed organic fertilizer (including cow manure, sheep manure, rabbit manure, etc.), and add appropriate amount (40 or 50 or 60 kg per mu) of compound fertilizer (high concentration of potassium sulfate, containing nitrate Nitrogen, total nutrient not less than 45%), apply 65 or 70 or 75 kg of ammonium bicarbonate per mu. Carefully prepare the soil before sowing, disinfect the soil with 3% (mass volume ratio) ferrous sulfate, and use 0.4 or 0.5 or 0.6 kg of ferrous sulfate solution per square meter. Make a seedbed (usually a flat bed) and level the bed surface. Bermudagrass can be sown and ...

Abstract

The invention discloses a method for improving drought resistance of paddy rice, alfalfa and Bermuda grass through low-salt induction treatment. The method comprises the following steps: A, planting: fertilizing, deeply ploughing and leveling a seedling land, fertilizing base fertilizers, preparing the land before sowing, sterilizing soil with ferrous sulfate, and leveling a bed surface; growing seedlings of paddy rice: firstly culturing seedlings in a certain farmland; cleaning alfalfa seeds, carrying out coating treatment on the seeds before sowing, ventilating, transmitting light and carrying out field management; carrying out lawn planting on Bermuda grass with two methods of seed sowing and rhizome propagation, and sowing seeds in late spring and early summer; B, seedling management: watering in seedling early period; and C, low-salt induction treatment: continuously pouring sodium chloride solution with low concentration for a given period on paddy rice, alfalfa and Bermuda grass seedlings in growth stage. The method is easy to implement, simple and convenient to operate and quick to take effect, the drought resistance of plants is improved during a short period, the crop yield during seasonal drought or at arid areas is improved, and the ecological benefits and economic benefits of lawn vegetation conservation and water and soil conservation are achieved.

Description

technical field [0001] The invention belongs to the field of resistance physiology of agriculture and animal husbandry, and more specifically relates to a method for improving the drought resistance of rice, alfalfa and bermudagrass through low-salt induction treatment. This method is applicable to the planting of rice, alfalfa and bermudagrass, water and soil conservation and ecological protection in arid regions of China and other regions when seasonal droughts often occur due to uneven distribution of rainfall in time and space. Background technique [0002] Rice is one of the important crops that humans depend on for survival. It is generally grown in tropical, subtropical and temperate regions. coastal plain Flooded cultivation in tidal deltas and river basins requires constant immersion in water during the growing season, so it is one of the crops that are not particularly drought-tolerant. Alfalfa is known as the "King of Forage Grass". It not only has high yield, bu...
