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

Embodiment 1

[0017] Embodiment 1: select the walnut variety to be Yangbi soaked walnut, planted in the mountains of Yangbi County between 1500-2500 meters above sea level, preferably 1900-2200 meters above sea level, the contour line is set as the plant distance, the specific plant distance is 8 meters, and the slope is vertical Set the row spacing, the specific row spacing is 8 meters, and the specific steps for building a garden are:

[0018] Pond digging: The planting pond is carried out in winter. The depth of the pond is: 80 cm long, 80 cm wide, 80 cm deep to 100 cm deep, 100 cm wide, and 100 cm deep; The upper mellow soil is placed on both sides of the horizontal direction of the planting pond, and the lower layer of raw soil is placed on the downhill direction of the pond, and the sun is not less than 30 days after the site preparation.

[0019] Fertilization: Use 50 kg of farmyard manure as base fertilizer for each walnut seedling, mix well with the surface soil obtained from the p...

Embodiment 2

[0023] Embodiment 2: select the walnut variety to be three walnuts, planted in the mountains of Dayao County between 1600-2400 meters above sea level, set the contour line as the plant spacing, the specific plant spacing is 6 meters, and the slope vertically is set as the row spacing, the specific row spacing 7 meters, the specific steps to build a garden are:

[0024] Pond digging: The planting pond is carried out in winter. The depth of the pond is: 80 cm long, 80 cm wide, 80 cm deep to 100 cm deep, 100 cm wide, and 100 cm deep; The upper mellow soil is placed on both sides of the horizontal direction of the planting pond, and the lower layer of raw soil is placed on the downhill direction of the pond, and the sun is not less than 30 days after the site preparation.

[0025] Fertilization: Use 40 kg of farmyard manure as base fertilizer for each walnut seedling, mix well with the surface soil obtained from the pond, and then backfill it at the bottom of the pond until it is ...

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....
