Problems solved by technology

This method is complex in technology, high in cost and low in success rate, and the most important thing is that the safety of genetically modified food is still in doubt
[0006] (3) increase the application rate of phosphorus fertilizer and potash fertilizer, improve the content of phosphorus and potassium in the fruit tree so as to reduce the osmotic pressure of protoplasm, reach the effect of improving drought resistance, this method can strengthen the drought resistance of apple tree and to the output of apple fruit and The quality has also improved to a certain extent, but there is also a big problem. The absorption of fertilizers by plants is not complete. Increasing the application of phosphorus and potassium fertilizers will also accumulate a large amount of inorganic salts in the soil that cannot be absorbed, destroying the soil structure. , causing secondary salinization of the soil for a long time
[0007] Although the above methods have obvious effects on improving the drought resistance of fruit trees, due to the defects of their respective methods and some objective reasons, the application in actual production often pays a high price, and the gain outweighs the gain

Embodiment 1

[0014] Embodiment 1, fertilization

[0015] 1. Base fertilizer:

[0016] Mainly apply organic fertilizers, and do not apply or apply less chemical fertilizers. The most suitable time for autumn application and autumn application of basal fertilizer is after harvesting mid-maturing varieties and before harvesting late-maturing varieties, generally from late September to early October.

[0017] Organic fertilizers have many advantages over chemical fertilizers:

[0018] (1) High organic matter content: Due to the high organic matter content, it can improve soil physical and chemical properties after application, and enhance the ability of soil water retention, fertilizer retention and fertilizer supply. High-quality organic fertilizers also have the characteristics of extremely high content of amino acids and potassium fulvic acid, which are suitable for organic agricultural production;

[0019] (2) High content of beneficial microorganisms: After entering the soil, it contai...

Embodiment 2

[0036] Embodiment 2, irrigation

[0037] If conditions permit, the use of infiltration irrigation or drip irrigation technology, combined with fertilization technology and betaine, can effectively play the role of water saving and drought. The cost of constructing seepage irrigation or drip irrigation facilities is about 400 yuan per mu. If the conditions do not allow construction, the irrigation method of the traditional method can also be used.

[0038] When using the betaine aqueous solution alone, use the configured betaine aqueous solution to water the base of the apple tree, and then irrigate to make the betaine go deep into the soil and be easy to absorb by the roots; branches and leaves are sprayed.

[0039] The watering period of apple trees should be determined according to the rainfall, soil water shortage and water demand of fruit trees. It is necessary to master the principle of "watering with drought" and pay equal attention to watering, drainage, conservation ...

Abstract

The invention belongs to the technical field of fruit tree planting, and discloses a water and fertilizer management method for apples under drought stress. The management method is characterized in that the drought resistance ability of apple trees is improved through the utilization of glycine betaine, fertilization and irrigation. The management method is energy-saving and environment-friendly, has no damage to soil, and can protect soil; the occurrence of diseases and pests can be inhibited to a certain extent, so as to reduce the consumption of chemical fertilizers and pesticides, and achieve edible safety of products; the yield and quality of apples are improved, and the pure flavor of the original variety is preserved.

Description

technical field [0001] The invention relates to the field of fruit tree planting, in particular to a water and fertilizer management method for apples under drought stress. Background technique [0002] Apple is a plant of the genus Malus in the subfamily Rosaceae, a deciduous tree. Apple fruit is rich in minerals and vitamins, and is the most commonly eaten fruit for people. Apple is one of the main fruit tree varieties cultivated in northern my country, and also one of the main economic crops in agricultural production in my country. Most of them are planted in arid and semi-arid areas, and often have a great impact on the quality and yield of apples due to drought. [0003] There are mainly three kinds of technical means that can effectively improve the drought resistance of apple trees: [0004] (1) Use drought-resistant varieties as rootstock grafting. This method has an obvious effect on improving the drought resistance of apples, but the amount of manual labor is la...
