Method for improving citrus fruit quality through moisture-permeable plastic film mulching water control and application

Abstract

The invention belongs to the technical field of fruit tree planting, and discloses a method for improving citrus fruit quality through moisture-permeable plastic film mulching water control and application, and the method comprises the following steps: selecting a breathable and waterproof reflective plastic film, and laying the reflective plastic film in a citrus garden; according to the state of the citrus leaf, judging the requirement of the citrus tree for moisture; the citrus trees are irrigated in an under-film drip irrigation mode based on the judgment result of the requirement of the citrus trees for water. According to the method, a breathable and waterproof reflective mulching film material is selected, the requirement of a tree body for moisture is judged according to the state of citrus leaves, moisture is supplemented through drip irrigation under the mulching film, the drought risk caused by long-term water control is overcome, laying can be carried out 1-2 months earlier than that of a traditional method, laying can be carried out under the high-temperature weather condition, and the yield is increased. The method has no influence on citrus root systems and tree bodies, can significantly improve the soluble solid content and appearance coloring of citrus, makes citrus appear on the market in advance, improves the high-quality fruit rate, and significantly improves the economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a method and application for improving the quality of citrus fruits by covering with moisture-permeable plastic film to control water. Background technique [0002] At present, plastic film mulching technology is a farming technology widely promoted in agricultural production. It can not only control the water in the fruit garden during the fruit ripening period, increase the light, and improve the quality of the fruit; it can also inhibit the evaporation of soil water, store water and keep moisture, and increase temperature. Heat preservation, protect the soil surface, improve soil physical properties, and increase water use efficiency. In the 1970s, China began to carry out research on the application effect of film mulching on fruit trees. Studies on apples, nectarines, grapes, loquats and other fruit trees have shown that laying reflective film on the...

Problems solved by technology

[0006] (1) In the existing method of improving the quality of citrus by covering with plastic film, the plastic film is laid randomly, there are single tree laying, single laying, or the gap between the film and the film is not tightly connected, and the depth of the drainage ditch is not deep enough, etc., resulting in poor water control. Completely, not as expected

[0007] (2) The existing citrus planting technology or the method of improving the quality of citrus by mulching plastic film is insufficient to judge the degree of water control, resulting in insignificant improvement of fruit quality or affecting the normal growth of citrus trees

[0008] (3) After long-term laying of reflective plastic film, if reasonable irrigation is not carried out under drought conditions, it will affect the respiration of citrus roots and the tree will lack water. In severe cases, it will lead to fruit drop, tree weakness, and even dead trees; Reflective mulch is prone to mirror reflection, which may cause fruit burns

[0010] (1) After the plastic film is covered, the interface between the film and the film, the trunk of the citrus tree, etc. are the main places where water seepage is likely to occur; and after the plastic film is covered, the infiltrated water is difficult to evaporate, which will lead to failure to achieve the desired effect or even lead to quality decline , the specification of laying operations is not involved in the current application of similar technologies;

[0011] (2) The judgment of soil water holding capacity after laying reflective film in citrus orchards is one of the main reasons affecting the effect of improving the quality of citrus after laying. At present, most of the tests use soil moisture detection equipment or take soil samples to the laboratory for soil analysis. The water holding capacity in the water can only be used to guide irrigation in the future. This method is inefficient and the cost of detection and analysis is high;

[0012] (3) Blocking rainwater is one of the main principles of mulching. Therefore, in the selection of materials, the water control effect should be given priority. The use of breathable and impermeable materials can ensure that the roots are not stuffy. The material of the reflective film is less;
