Establishment method for walnut grove on Yunnan mountain land

Abstract

The invention discloses an establishment method for a walnut grove on Yunnan mountain land. The method is characterized in that splitting and digging are conducted between every two rows of walnut trees along the contour line year by year to form straight ridges, and the splitting and digging height is 5-10 cm every year; the soil ridges are built, meanwhile mellow soil on a platform is levelled,weeds obtained through soil ridge splitting and digging and platform clean-up are piled on ridge heads along the ridge line, and then immature soil obtained through soil ridge splitting and digging ispiled on the weeds. By adopting the method for grove establishment, the construction cost is reduced, soil quality is improved constantly, damage to the vegetation is smaller, the vegetation can easily recover, and the walnut setting rate is generally increased by 2.8%-20%.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry planting, and in particular relates to a method for building a walnut forest in mountainous areas of Yunnan. Background technique [0002] my country's walnut forests are mainly planted in mountainous areas, especially walnut forests in Yunnan Province in Southwest my country. However, most of the mountainous areas have outstanding problems such as shallow soil layers and poor soils. Soil improvement is the key to whether mountain orchards can achieve higher economic benefits. The construction of traditional mountain gardens is usually completed at one time, and the construction of gardens requires a step-by-step process. When building the garden, it is required to widen the terraces of each floor as much as possible to slow down the slope, and to open water collecting ditches on the inner side of the slope, and to open vertical ditches from top to bottom to reduce the erosion of rainwater....

AI Technical Summary

Problems solved by technology

[0003] The mountainous terrain of Yunnan is complex, and the altitude difference between the foot of the mountain and the top of the mountain is obvious, resulting in a huge amount of garden construction work, and it is difficult for conventional construction machinery to intervene, resulting in a long construction period. High input and economic input

[0004] On the other hand, the mountain soil in Yunnan is usually red soil, which is highly dispersed and not easy to flocculate. Therefore, the red soil structure has poor water stability. One-time gardening will seriously damage the mountain vegetation. Once the rainy season enters, the situation of water and soil loss is very serious, and repeated construction is required in the later stage Soil ridges: The cost of soil in the mountains of Yunnan is mainly red soil, which contains more iron and aluminum, which is acidic soil and has relatively poor fertility. In addition, the leaching of soil nutrients and organic matter caused by water and soil erosion will further reduce the fertility of mountain soil. It is necessary to fertilize rationally at any time according to the actual growth of the walnut tree; however, water and fertilizer management may go to the other extreme. Under the condition of sufficient water and fertilizer, the vegetative growth of walnut is too vigorous, resulting in delayed or no fruit.
