Method for planting elymus cylindricus under typical grassland rain-fed conditions

Abstract

The invention discloses a method for planting elymus cylindricus under typical grassland rain-fed conditions. The method comprises the following steps of performing hummel treatment by selecting local wild elymus cylindricus seeds or local elymus cylindricus seeds which are locally introduced and domesticated successfully as elymus cylindricus seeds and sowing the elymus cylindricus seeds; sowing the elymus cylindricus seeds and legume seeds in a mixed manner in the middle ten days or the last ten days of the May or the first ten days of the June of the current year after performing soil preparation on a selected land and applying base fertilizers to the land under the conditions that the sowing quantity of elymus cylindricus is 10.5-24kg / hm2, the sowing quantity of legume is 7.88-15kg / hm2 and the sowing depth is 3-4cm; pressing the land; performing ripping on the land before seedlings emerge and after the land is wetted by rain; and clipping the elymus cylindricus every year from the last ten days of the July of the following year under the condition that the stubble height is greater than or equal to 5cm. The elymus cylindricus can be planted in the large area of typical grassland under the rain-fed condition, and the planting cost is reduced.

Description

technical field [0001] The invention relates to planting technology, in particular to a method for planting Elymus cylindrica under rain-fed conditions in a typical grassland area. Background technique [0002] Elymus is an important genus in the grass family Triticum, and most species of Elymus are important components of grasslands and meadows. Moreover, many species of Elymus genus are excellent forage grasses, with a large number of reproductive tillering branches and high feeding value. [0003] Elymus cylindricus (Franch.) Honda, a species of Elymus cylindricus (Franch.) Honda, is a perennial grass with high feeding value. Elymus cylindrica is distributed in my country's Inner Mongolia, Hebei, Sichuan, Qinghai, Xinjiang and other provinces, and also in the former Soviet Union, Mongolia, North Korea, and Iran abroad. Elymus cylindrica is tender and palatable before flowering. Therefore, horses, cattle, and sheep like to eat Elymus cylindrica from turning green to befo...

AI Technical Summary

Problems solved by technology

However, the planting method of Elymus cylindrica based on irrigation conditions makes the planting cost of Elymus cylindrica higher (such as the cost of equipment required for irrigation, the cost of manpower required for irrigation), and is not suitable for large-scale promotion in typical grassland areas
