Method for cultivating soap nut trees

Abstract

The invention discloses a method for cultivating soap nut trees. The site conditions are as follows: a farmland is adjacent to the land and has better water draining, and the underground water level is less than or equal to 80 centimeters; the soil condition is that the soil is yellow brown soil. The cultivation technology comprises the following steps of: improving soil and applying fertilizer, ditching and preparing soil in autumn and winter of the year before planting nursery-grown plants, and returning mellow soil back to a pit to forest in spring of the next year after frozenly cutting in winter. The initial stand density is as follows: the trees are planted in the last ten days of February and the first ten days of March in each year and the row distance of the trees is 1.5*3 cm; after one year, a seedling is planted between the trees and the row distance of the trees is adjusted to 3*3 m. A process of pruning comprises the following steps of: continuously reforming and pruning the trees in a growing season and keeping the apical growth dominance; adjusting trunks to the height of 1.5-1.8 m through pruning in the following year and culturing skeleton branches at the same time. The insect pest is as follows: long-horned beetle borer pests are mainly prevented and treated. Through utilizing the method provided by the invention, the year increment of the soap nut trees reaches 80-120 cm, the year increment of the diameter reaches 2.2-2.8 cm, and good greening seedlings with the seedling diameter of 8-12 cm can be obtained by utilizing the nursery-grown plants of 5-6 years old.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating Sapindus sapindus in hilly areas. Background technique [0002] Sapindus (scientific name: Sapindus), Compendium of Materia Medica is called Sapindus, Sichuan is called Oil Sapindus, Hainan Island is called Bitter Tree, Taiwan is also known as Huangmuzi, also known as Oil Luoshu, Washing Fruit, Soap Fruit Tree . Sapindaceae and litchi and longan belong to Sapindaceae. According to legend, the wooden stick made of the wood of the Wuzai tree can exorcise demons and kill ghosts, so it is called Wuzai. The Latin scientific name Sapindus is the abbreviation of soapindicus, which means "soap of India", because its thick fleshy peel contains saponin, as long as it is rubbed with water, it will produce foam, which can be used for cleaning and is one of the main cleaning agents in ancient times. . There are about 13 species distributed in...
