Embodiment 1

[0024] Embodiment 1 of the present invention: the high-position stubble and rejuvenation method of shrub Nitraria japonica, in Huaxi District, Guiyang, Guizhou Province: in the early winter period, the main method is to stage and interlace the stubble year by year, that is, the rejuvenation and rejuvenation cycle of the stubble is 1 year, With 1 row every 2 rows, with a row distance of 4 meters, use a sharp tool to cut off the entire clump in the stubble area at one time. The height of the stubble is 50 cm from the ground. It can effectively reduce the hazards of water erosion on rocky ground surfaces, increase the yield of shrub feed, and increase the emergence rate of germination after flat stubble, which is beneficial to the next stubble utilization. Whenever the stubble is stubbled, the tillering point of the plant must not be damaged. Shrubs are younger, especially shrubs under 1 age should not be stubbled during the growing season.

Embodiment 2

[0025] Embodiment 2 of the present invention: the high-position flat stubble rejuvenation method of shrub Nitraria japonica, in Dushan, Guizhou: in the early winter period, the main method is to stage and interleave year by year flat stubble, that is, the flat stubble rejuvenation update utilization cycle is 1 year, and every 1 row of flat stubble every other row, with a row distance of 4 meters. Use a sharp tool to cut off the entire clump in the flat stubble area at one time. The height of the stubble is 50 cm from the ground. The stubble is leveled once a year, and the next time the stubble is raised by 3 cm.

[0026] In the above examples, compared with non-level stubble, the total biomass can be increased by more than 50%, and the leaf biomass can be increased by 60-70%, resulting in greater economic and ecological benefits. The white thorn flower should not be stubbled during the growing season.

Abstract

The invention discloses a method of high-level stumping and rejuvenating of bush sophora davidii. The problem that due to the fact that the age of sophora davidii bush is increased, growth declination is prone to occurrence is solved. More and more research and development of existing stumping and rejuvenating and matching technologies appear, specially for recent years, vegetation of desertification regions restores, stumping and rejuvenating utilization technology is popularized at home and abroad, taking Inner Mongolia for example, a machine special for stumping and rejuvenating and cutting irrigation of caragana korshinskii is developed, but crops for rotation are low in this technology, implementation is not easy to carry out in southwest mountainous areas, and the promotion is difficult. Compared with the prior art, the high-level stumping and rejuvenating technology is adopted, the biological yield of bushes is increased, mechanization of stumping is achieved, the method of high-level stumping and rejuvenating of the bush sophora davidii has the advantages of being easy to operate and promote, and greater promotion potential and practical value in southwest mountainous areas are achieved. According to the method of high-level stumping and rejuvenating of the bush sophora davidii, the operation steps are simple, the promotion is easy, water erosion hazards to stony ground can be effectively reduced, the yield of bush feed is increased, sprout occurrence rate is enhanced after stumping is conducted, plant diseases and insect pests are eliminated, and better economical and social benefits are produced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for rejuvenating shrub Nitraria japonica with high-position stubble. Background technique [0002] White thorn flower (Sophoradavidii) is a perennial shrub of the genus Sophora genus Fabaceae. It is one of the native shrubs widely distributed in the southwest karst area. It has become a pioneer species in the restoration process of rocky desertification vegetation in this area. Under the implementation of a series of large-scale ecological projects, such as "returning farmland to forest and grassland" and "rocky desertification control", and under the background of the "big province strategy of ecological animal husbandry" proposed by various provinces in Southwest China, the shrub plants of Nitraria japonica are due to It has stronger adversity resistance and adaptability than herbs and trees, and in ecological restoration projects and feed projects, it has becom...
