Long-acting fertilization method for carya illinoensis

Abstract

The invention belongs to the field of carya illinoensis planting, and particularly discloses a long-acting fertilization method for carya illinoensis. The long-acting fertilization method comprises the following specific steps of S1, outwards expanding by 10 cm-20 cm by taking a trunk of the carya illinoensis as a center, and dividing into a circular fertilization area; S2, arranging a circle of isolation cover around the circumferential line of the circular fertilization area, inserting the isolation cover into the ground by 3 / 5 of the height, and enabling the remaining 2 / 5 part of the isolation cover to extend out of the ground; S3, arranging a circle of fertilizer retention device of a conical structure along the outer periphery of the trunk of the carya illinoensis in the circular fertilization area; S4, paving a humic layer with the thickness of 3 cm-5 cm on the ground below the fertilizer retention device, and then paving a permeable sponge layer with the thickness of 2 cm-4 cm on the humic layer; and S5, uniformly spreading slow-release fertilizer into the fertilizer retention device, arranging an annular water spraying pipe on the isolation cover, and enabling the slow-release fertilizer in the fertilizer retention device to permeate into the circular fertilization area by utilizing the annular water spraying pipe. Fertilization is completed in the irrigation process, and the effect of slowly releasing nutrients for a long time is achieved.

Description

Technical field: [0001] The invention relates to the field of planting pecans, in particular to a long-acting fertilization method for pecans. Background technique: [0002] Hickory is a world-renowned high-grade dried fruit, an oil tree species and an excellent tree species for both wood and fruit. Walnut has long been loved by people as a dried fruit, but because of its hard shell, it is not easy to peel off, and its main way of utilization is to use it as oil and food raw materials. Thin-shelled pecans will be consumed much more than regular walnuts due to the ease with which the shells are peeled off, like peeled peanuts. The trunk is straight, the material is solid, the texture is fine, elastic, and it is not easy to warp. It is an excellent material for making furniture. The nut shell is thin and easy to peel, the kernel is thick, rich in fat, and tastes sweet. It is the raw material for dried fruit and oil extraction. . [0003] Thin-shell hickory has deep main roo...

AI Technical Summary

Problems solved by technology

During the planting process of pecans with thin shells, manpower is mainly used for fertilization, which requires a lot of labor, and the fertilizer is easy to lose, and the fertilizer absorption effect is average.
