Embodiment 1
[0022] Embodiment 1: a kind of rapid planting method of Nitraria japonica, its specific steps are as follows:
[0023] 1. Seed collection: The seeds of Nitraria japonica usually mature in July to September, and the fruit can be collected from green to yellowish brown, and the pods become hard and dry. Seed collection in July. After the seeds are collected, put them in the sun for 10 or 11 or 12 or 13 or 14 hours in time, beat them with sticks after drying, remove short branches, and clean the seeds by winnowing. After natural drying, store them in a dry and ventilated room with cloth bags.
[0024] 2. Nursery selection: choose sandy loam soil with low groundwater level and good drainage, and 30% river sand can be added to loess for improvement; clay, low-lying land, saline-alkali land and plots with high groundwater level are prone to root rot, so it is not suitable For nursery ground. It was leveled in March, deep plowed, fertilized, furrowed, irrigated, and waited for plan...

Abstract
The invention discloses a method for quickly planting sophora davidii. The method comprises the following steps of: A, seeds collection, namely, storing the seeds in a dry and ventilated room; B, nursery garden selection, namely, flattening, ploughing under to great depth, fertilizing, bedding, irrigating and preparing to plant; C, soil preparation and nutritional soil allocation, namely, preparing seedbed and flattening bed surface; D, bud forcing treatment before sowing, namely, sterilizing the seeds by using 0.5 percent solution of potassium permanganate before sowing; E, sowing, namely, spring sowing, sowing in line, sowing by drilling ditch and watering to remain floor wet; F, seedling management, spraying the solution of potassium permanganate at the seedling stage, spraying continuously, preventing grub underground insects at the young seedling stage and seedling for sell; and G, tree planting, namely, tree planting in spring and autumn, selecting biennial nursery stock to cut branches at the 10-centimeter distance away from the root and digging 40-centimeter depth pits to plant, wherein 269 to 333 plants are planted per mu. The method has the advantages of realizing rapid afforestation of the sophora davidii in a shot time and achieving the ecological benefit of vegetation recovery and water and soil conservation and the economic benefit of green manure and feed development, along with simple and convenient operation and quick effect.
Description
technical field [0001] The invention belongs to the technical field of ecological planting, and more specifically relates to a rapid planting method of Nitraria japonica, which is applicable to loess hills, ravines, hillsides and field ridges in vast areas such as North China, East China, Northwest and Southwest China to restore vegetation, Soil and water conservation and development as fuelwood, green manure and fodder. Background technique [0002] White thorn flower (Sophora davidii), also known as wolf tooth thorn, iron horse burnt, bitter thorn, is a shrub of Papilionaceae Sophora genus, 1m~2.5m high, widely distributed in Northwest, North, East and Southwest China, in Henan , Hebei, Shanxi, Hunan, Hubei, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan and other places are distributed. It mostly grows on arid sunny slopes and is an extremely drought-tolerant clumped shrub. It is mostly distributed at an altitude of 1000-1800m, and it grows in mountainous areas below an altitu...
