Embodiment 1

[0014] A method for citrus orchard soil straw covering, the steps are:

[0015] A, 2009 spring (March-April) implement straw mulching within 2 days after fertilization along the drip line in Xiaofuling Village, Xijiadian Town, Danjiangkou City, Hubei Province (20×30cm).

[0016] B, depending on the size of the citrus tree, each citrus tree is covered with 2 or 2.4 or 2.8 or 3 kilograms of dry straw.

[0017] C, the straw-covered part is the area along the trunk to the drip line of the crown, with a thickness of about 10 cm, and a small amount of soil is pressed on the edge to prevent it from being blown away by the wind.

[0018] The results show that the citrus orchard soil straw mulching treatment carried out by this method reduces the average amount of soil surface runoff by 0.08L / m compared with the contrast (farmers' customary practice, no straw mulching) 2 (12.3%); the water content of the soil in the covered area is higher than the control 3-7 percentage points, and th...

Abstract

The invention discloses a method for covering orangery soils with straws. The method comprises the following concrete steps of: A. ditching and fertilizing the soil in March to April of every spring and covering the soil with straws within 1-3 days; B. covering each orange tree with 2-3 kg of dry straws according to the size of the orange tree body no matter what the planting density is; and C. carrying out straws covering in the region along a tree trunk to water drips of a tree crown in the thickness of 9-10 cm and placing soil-pressing blocks at the edges so as to prevent the straws from being blown away. The invention has simple and convenient method, convenient operation and low cost, effectively increases the water content, the organic matter and the mineral nutrient content of the orangery soil, reduces the fluctuation of the temperature and the humidity of the soil as well as the water and soil loss and the nutrient eluviation of dry sloping fields caused by rainwater, effectively controls the weed growth in the orangery, decreases the usage of herbicides and can promote the high yield and the superior quality of oranges and the sustainable development of the orange industry.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency and environment-friendly cultivation of fruit trees, and more specifically relates to a method for mulching the soil of citrus orchards with straw, which is suitable for citrus orchards in southern China, especially citrus orchards on dry slopes in hilly and mountainous areas. Background technique [0002] Citrus is the main fruit tree in southern China, especially in the Yangtze River Basin. The quality of citrus production has an important impact on southern fruit production and local economic development. Because citrus is mostly planted on hilly and dry slopes, the surface soil of orchards has been easily eroded by rainwater for a long time, resulting in a continuous decline in soil fertility, which in turn affects the growth of fruit trees. In addition, rice straw in many areas in the south is not well utilized, and it is often burned in the field, which not only loses nutrients, but ...
