Interplanting method of bletilla striata and citrus

Abstract

The invention discloses an interplanting method of bletilla striata and citrus and relates to the technical field of composite management and cultivation of agriculture and forestry. The method comprises the steps of land selection and land preparation, wherein sandy loam soil plots with an 80-90-cm active soil layer, the underground water level of 1.5 m or below, the soil pH of 6.5 and the organic matter content of 3% or above as an selected orchard site; transplanting of fruit trees, wherein annular adobe is built around each fruit tree with the plant as a circle center, and fertilizing ditches are dug in the ground of the periphery of the annular adobe; soil overturning and ridge arrangement, wherein weed seeds are killed with trifluralin, and manure and compost are applied in the winter of the current year when the citrus trees fruit; planting of bletilla striata tubers, wherein bletilla striata tubers grown in the same year and provided with buds are cut into small pieces in the spring of the next year, and every 3 seed tuber pieces are planted in each hole and placed flat at the bottom of the hole; prevention and control of citrus fruit tree pests and bletilla striata diseases and pests; fruit tree management and bletilla striata management; harvesting of bletilla striata. The method achieves the purpose of interplanting bletilla striata and citrus, can realize double harvesting of the citrus fruit trees and the Chinese medicine bletilla striata, reduces the production cost and increases the income of fruit farmers.

Description

technical field

[0001] The invention relates to the technical field of agroforestry compound management and cultivation, in particular to a method for interplanting bletilla striata and citrus. Background technique

[0002] Because the environment and soil in the mountains of Sichuan have the advantages of high air humidity, sufficient soil moisture, and high light intensity, farmers in the mountains usually plant all kinds of fruit trees on the mountains and flats, such as orange trees and pomelo trees. The growth period of fruit trees is generally more than 5 years. During the 5-year growth period, if the orchard is abandoned, it will inevitably cause a waste of land resources, and it is also not conducive to improving the income level of fruit farmers. In the early stage of fruit tree orchard construction, the land utilization rate is low, weeds grow fast, there are many diseases and insect pests, and the management cost is high. There is only input but no output, and fru...
