Utilization method of southeast asia cherry ridge palisade

Abstract

The invention provides a utilization method for the terrace paling of Gliricidia sepium plants. The method selects the Gliricidia sepium with quick growing speed, slash-resistance, strong nitrogen fixing capacity, extensive management and diversified purposes, and adopts the seeding raising transplanting, close planting and stunting methods, and since the start of the rainy season, the Gliricidia sepium plants are planted on the terrace of the dry sloping field in the tropical region for two to three rows with a delta-shape according to the plant spacing of 30 cm*40 cm to 40 cm*50 cm. When the Gliricidia sepium plants grow higher than 1.5 m, the Gliricidia sepium plants are clipped 50 cm plus or minus 5 away from the field, and paling is formed after two years of planting. The surface runoff can be reduced by 167470.87m<3>within 3 years by using the method; the soil loss can be reduced by 12986.8 (t / km<2>.a); the leaves can be used as the green manure, and thereby the soil organic matter can be improved by 10.5 to 17 percent; the annual output of the fresh leaves reaches 79860 kilograms / acre, and the Gliricidia sepium plants can be used as the feeding stuff through sun drying and crushing; the annual output of the branches reaches 88440 kilograms / acre, and the branches can be used as the fuel. The effective combination of the economical and the ecological benefits can be realized by adopting the method.

Description

technical field [0001] The invention relates to the technical field of planting forestry crops, in particular to a method for utilizing ridges and fences of Nanyang cherry plants. Background technique [0002] Nanyang cherry (Gliricidia sepium (Jacq.) Steud.) is a tropical fast-growing leguminous tree species, native to Central America, and its natural distribution area is from 25°30' north latitude to 7°30' south latitude, with an altitude below 1500 meters. It is now planted in many tropical regions of the world, such as West Africa, West Indies, tropical America, and South Asia. Nanyang cherry has the characteristics of strong nitrogen fixation, rapid growth, cutting resistance, strong applicability, hard wood, high germination rate after felling, and wide adaptability to soil. It can adapt to acidic soil with a pH value of 4.5-6.2. Fertile sandy soils, heavy clay soils, calcareous soils and alkaline soils. Both seeds and seedlings can germinate and grow normally, the s...
