Problems solved by technology

In the practice of jujube production, the soil in some areas is relatively sticky, which leads to poor soil ventilation and affects the normal growth of plants.
[0003] Existing aerobic irrigation is mostly rice aerobic irrigation, which uses physical methods, that is, directly aerates oxygen into the water pipe, and then irrigates on the surface. The oxygen content of the water is generally less, and a lot of oxygen is lost during the irrigation process, so the effect is mediocre

Embodiment 1

[0058] A method for increasing oxygen and saving water for Lingwu jujube, comprising the following steps:

[0059] S1 covered with plastic film: the ground where the jujube tree is located is covered with black plastic film.

[0060] S2 Lay buried drip irrigation pipes: Lay a buried drip irrigation pipe on both sides of each row of jujube trees. The distance between the buried drip irrigation pipes is 50cm from the jujube trees, and the distance between the drip irrigation pipes and the surface is 25-30cm. The distance between the drip holes on the drip irrigation pipes The thickness of the drip irrigation pipe is 30cm, the wall thickness of the drip irrigation pipe is 0.2mm, and the water output of the drip hole on the drip irrigation pipe is 3L / h.

[0061] S3 Calculation of irrigation water volume: Calculate the single irrigation water volume by using the drip irrigation treatment irrigation quota calculation formula.

[0062] The calculation formula of drip irrigation trea...

Embodiment 2

[0081] A method for increasing oxygen and saving water for Lingwu jujube, comprising the following steps:

[0082] S1 covered with plastic film: the ground where the jujube tree is located is covered with black plastic film.

[0083] S2 laying buried drip irrigation pipes: Lay a buried drip irrigation pipe on both sides of each row of jujube trees. The thickness of the drip irrigation pipe is 30cm, the wall thickness of the drip irrigation pipe is 0.2mm, and the water output of the drip hole on the drip irrigation pipe is 3L / h.

[0084] S3 Calculation of irrigation water volume: Calculate the single irrigation water volume by using the drip irrigation treatment irrigation quota calculation formula.

[0085] The calculation formula of drip irrigation treatment irrigation quota is: M=0.1*Rs*P*H*(W1-W2) / η

[0086] In the formula: M—design irrigation quota (mm);

[0087] Rs—average soil bulk density of planned wet layer (g / cm 3 );

[0088] P—soil moisture ratio (%);

Abstract

The invention provides an oxygenating water-saving irrigation method for jujube. By combining a physical method with a chemical method, the amount of dissolved oxygen in water can be accurately controlled; meanwhile, an underground irrigation water supply mode is adopted, so that oxygen is fully utilized, fungi, bacteria and actinomycetes in rhizosphere soil of jujube trees and related enzyme activities are improved, and further the yield and the sweetness of the jujube are effectively improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an oxygen-increasing and water-saving irrigation method for Lingwu long jujube. Background technique [0002] As one of the three major vegetative organs of plants, the root plays an extremely important role in the growth and development of plants. It can not only support and fix plants, absorb water and mineral nutrients, but also secrete organic matter and participate in the synthesis of many organic matters. The growth and development of the plant directly depends on the growth of the root system, and the root environment and the respiration capacity of the root system are important factors affecting the normal growth of the root system. Excessive soil moisture and excessive soil compaction will have a greater inhibitory effect on the growth of crop roots. Some scholars at home and abroad believe that impermeable soil or insufficient oxygen in the soil is one of the ma...
