Embodiment Construction

[0038] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] The Dazi County Ecological Experimental Station in Lhasa City conducts specific experiments in accordance with the following steps:

[0040] (1) Variety selection

[0041] The species of Elymus is selected from Elymus weeping.

[0042] (2) Site selection and preparation

[0043] Choose plots with strong water and fertilizer retention, convenient drainage and irrigation, and good soil and fertilizer conditions; before sowing, the plots should be plowed to remove stubble, and poor soil should be combined with soil plowing to apply appropriate amount of manure.

[0044] (3) Sowing method

[0045] The seed field of Elymus similarius was drilled by uni-sowing, with a row spacing of 35 cm and a sowing depth of 1 to 2 cm.

[0046] (4) seeding rate

[0047] The seeding rate of Elymus is 15kg / hm 2 -30kg / hm 2 .

[0048] (5) Sowing...

Abstract

The invention relates to the field of plant planting, in particular to a Tibet region elymus dahuricus seed cultivating method. A high-yield and high-quality variety with high ecological adaptability is selected; a parcel which is high in water and fertilizer preserving capacity and good in soil and fertilizer condition and facilitates irrigation and drainage is selected, a single sowing mode is selected for sowing in strip, and sowing can be carried out in late spring, summer and early autumn; top application of urea is carried out on elymus dahuricus grassland growing in the second year at the elongation stage, potassium nitrate is sprayed at the tillering stage and the elongation stage, and proper field management is carried out. The yield of elymus dahuricus seeds in the Tibet one-river-two-tributaries region can be effectively increased.

Description

[0001] Technical field: [0002] The invention relates to the field of plant planting, in particular to a method for cultivating Elymus chinensis seeds in Tibetan areas, which is used to increase the yield of Elymus chinensis seeds in the "one river and two rivers" area of ​​Tibet. [0003] Background technique: [0004] For a long time, due to the constraints of natural geography, resource conditions, technical level, traditional management methods and other factors in Tibet, the development level of forage seed breeding and processing technology has been relatively slow, which does not match Tibet's status as one of my country's five major animal husbandry provinces . Forage grass or fodder crop seeds cultivated in Tibet cannot be produced locally or most of them rely on seed transfer from outside the region, which has become a bottleneck for the leapfrog development of grassland animal husbandry in Tibet. Breeding high-quality forage seeds, developing seed processing technol...
