Problems solved by technology

[0003] People often use the topdressing method of covering the ground with fully decomposed manure and irrigating the chemical fertilizer with water. When this method is applied to fertilize, the proportion of fertilizer input per unit area is too large, which will increase the pH value of the soil and lead to secondary salinization of the soil.

Embodiment 1

[0044] The fertilization method of wolfberry trees under four years old is as follows:

[0045] After the soil thawed in the first ten days of April in the newly-built wolfberry garden, the site was prepared and planting holes were dug. The size of the planting hole was 50cm in diameter x 50cm in depth. mu. Mix fully decomposed sheep manure with part of the topsoil, apply it below 30cm, and then cover the remaining topsoil in the shape of a mound, sit the roots of the wolfberry seedlings in the new garden on the mound, and plant them with three burials, two steps and one lift. Planting wolfberry in the new garden, the planting process is completed within 7-10 days; water immediately after the planting is completed;

[0046] 2-4-year-old Chinese wolfberry before the germination of 2-4-year-old Chinese wolfberry in early April each year, apply 8kg of fully decomposed sheep manure to each plant; Radius is 30cm on the circle dig ring-shaped ditch fertilization, the depth of ring...

Embodiment 2

[0051] The fertilization method of wolfberry trees under four years old is as follows:

[0052] After the soil thawed in the first ten days of April in Xinjian Garden, the ground was prepared and planting holes were dug. The specifications of the planting holes were: diameter 40cm × depth 50cm, planting density: spacing between plants 1.4m×row spacing 2.8m; each plant of Lycium chinensis in Xinjianyuan was fully decomposed with 8kg of cow dung. Mix fully decomposed cow dung with part of the topsoil, apply it below 30cm, and then cover the remaining topsoil in the shape of a mound, sit the roots of the wolfberry seedlings in the new garden on the mound, and plant them by three burials, two steps and one lift. Planting wolfberry in the new garden, the planting process is completed within 7-10 days; water immediately after the planting is completed;

Abstract

The invention belongs to the technical field of high-yield culture of fruit trees of economic value in arid regions and semiarid regions and particularly provides a fertilization method for medlar aged no more than 4 years. As for the fertilization method for the medlar with the tree age of no more than 4 years provided by the invention, the medlar aged no more than 4 years comprises medlar in a newly-built garden and medlar aged 2-4 years; fertilization comprises application of basal fertilizers and application of additional fertilizers; and the fertilization method comprises performing deepapplication of fertilizers. According to the invention, the fertilization method of performing deep application of the fertilizers is adopted, so that the fertilizer absorption rate is improved and the fertilizer volatilization rate is reduced; the medlar can achieve higher yield through applying less fertilizers, so that the input amount of the fertilizers in unit area is reduced, thus the soil pH value is reduced from 8.57 to 7.23, the soil secondary salinization is relieved, the sustainable utilization of farmland is protected, the soil in an irrigated area is effectively prevented from being subjected to saline-alkali damage, and plantable species in saline-alkaline land are enriched.

Description

technical field [0001] The invention belongs to the technical field of high-yield cultivation of economic forest trees and fruit trees in arid and semi-arid areas, in particular to a method for fertilizing wolfberry trees less than four years old. Background technique [0002] Lycium barbarum is a saline shrub with strong stress resistance. It is also an important medicinal and economic tree species for the improvement and utilization of saline-alkaline sandy wasteland. It has become a dominant characteristic Chinese medicinal material and health-care fruit tree species in western my country. At present, the national wolfberry planting area is nearly 10,000 square hectares, and the industrialization development has begun to take shape. Lycium barbarum has also become the preferred economic tree species for the development and utilization of saline soil in arid areas. It has high economic development potential and ecological value in the ecological environment construction an...
