Embodiment 1

[0024] Embodiment 1, when described crop is fruit tree, take apple tree as example, introduce the specific application method of this method:

[0025] Step s101, applying soil water retaining agent: selecting a potassium polyacrylate-polyacrylamide copolymer soil water retaining agent. Apply in the early stage of fruit tree germination. When applying, dig pits between rows on both sides (or dig ring ditches around the fruit trees) at 1 / 3 to 2 / 3 of the vertical projection radius of the crown of each fruit tree, with a width, length, and depth of 30cm× 45cm×(40~60)cm, first fully mix it with soil, put it into the ditch in layers, cover the upper layer with floating soil, and fully irrigate once after the reagent is applied to ensure that the soil water-retaining agent can fully absorb water. It is advisable to apply 200-400g / tree for apple fruit trees over seven years old, and it can be appropriately reduced for fruit trees under seven years old, and it is recommended not to be ...

Embodiment 2

[0029] Embodiment 2, when described crop is melon and vegetable, take the melon and vegetable of greenhouse, greenhouse as example, introduce the specific application method of this method:

[0030] Step s201, application of soil water-retaining agent: select a potassium polyacrylate-polyacrylamide copolymer soil water-retaining agent, apply the soil water-retaining agent by hole application, the depth is 15cm, and the dosage of each plant is 5g / plant. The soil water-retaining agent is fully mixed with soil, and the surface layer is covered with soil.

[0031] Step s202, plant anti-transpiration agent application: select a typical metabolic plant anti-transpiration agent fulvic acid, and for the spraying of melons and vegetables, it is advisable to use a 200-350 times dilution (the mass ratio of water to Handilong). Spraying three times (pre-flowering period, fruit expansion period, fruit ripening period) can effectively improve fruit quality and reduce pests and diseases, and...

Abstract

The invention discloses a comprehensive water saving regulation method for fruit trees and vegetables comprising the following steps: soil water retaining agent is applied to the root zone soil of planted crops; plant antitranspirant is sprayed on the foliar of the crops; soil structural modifier is applied to the near surface top soil at the root zone of the planted crops. The method has the advantages that, the embodiment of the invention takes soil and crops as a whole; through combined application of the three agents of soil water retaining agent, plant antitranspirant and soil structural modifier, stereo and comprehensive regulation of the water status of soil and crops can be realized, and field water utilization efficiently is improved.

Description

technical field [0001] The invention relates to the technical fields of agriculture and water saving, in particular to a comprehensive water saving control method for fruit trees and vegetables. Background technique [0002] As an important resource for human survival and development, water has become the primary issue of the global resource environment. It not only affects and restricts the sustainable development of modern society, but also directly threatens the survival and development of human beings, thus arousing widespread concern in the world. How to truly improve the effective utilization of water resources and promote the sustainable development and protection of water resources has become an urgent problem faced by all countries in the world. For example, the growth, development and yield formation of crops are taken as a production process, and the efficient use of agricultural water resources is, in the final analysis, to increase the economic output per unit ...
