A kind of betel nut root restoration method for planting betel nut on sloping land

Abstract

The invention provides a method for repairing the betel nut root system of betel nut planting on a sloping field. During the betel nut planting process, the root system of the betel nut is repaired by subsoiling the inter-row soil, layered fertilization of the rhizosphere soil, surface mulch and rhizosphere mulching; Among them, the chisel type subsoiler is used for inter-row soil deep loosening, and the layered fertilization of the rhizosphere soil is to apply silicon-calcium-magnesium soil conditioner to the bottom layer, and Niannianle bio-organic fertilizer to the middle layer; superphosphate and superphosphate to the upper layer. Compound fertilizer; the surface mulch is covered with mulch manure and mellow soil in turn, and the mulch manure is a mixture of cassava slag, coconut bran and mushroom slag; the rhizosphere mulch keeps the mellow soil layer moist, and the water holding capacity is 30 -40%. The method for repairing the betel nut root system of the present invention can effectively regulate the micro-ecological environment of the rhizosphere, stimulate the growth of the root system, promote the regeneration of the root system of the betel nut on the surface and underground, realize the restoration of the root system of the areca nut, promote the absorption of nutrients by the root system of the areca nut, and increase the yield of the areca nut.

Description

technical field [0001] The invention relates to the technical field of plant planting and repairing, in particular to a method for repairing areca nut roots in slope land betel nut planting. Background technique [0002] Betel nut (Areca catechu L.) belongs to the monocotyledonous plant class, primary order, palmaceae, betel nut genus evergreen trees, with erect stems, tree-like shape, 10-30 meters high, and obvious ring-shaped leaf scars. It is the main cultivated tree in Hainan Province. One of southern medicine. The planting area of ​​areca nuts in Hainan is nearly 1.4 million mu, accounting for 99% of the country, and it is the main producing area of ​​betel nuts in China. [0003] Hainan betel nut orchards have been under extensive management for a long time, and the planting is scattered, and the growers have not dealt with the root system scientifically. The root system of betel nut grows all year round, and the root system protrudes from different directions. The h...

AI Technical Summary

Problems solved by technology

The area of ​​Hainan betel nut planted on slope land accounts for more than 92%. However, due to the influence of tropical rainforest climate and soil conditions in Hainan and the fact that the betel nut root system is a group of roots, the long-term exposed root system tends to easily limit the betel nut’s absorption of soil nutrients and affect the growth of betel nut. Potential threats to production, high surface temperature, and difficulty in new roots; and it will also lead to a decline in disease resistance, susceptibility to diseases, and weakening of soil fixation. In betel nut orchards with root damage, leaf spot, anthracnose, etc. The incidence is serious, which is more than 34% higher than that of the root healthy growth garden. Severe disease causes leaf fall, baldness, etc., and the serious loss of soil nutrients in betel nut slopes and other problems
