Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with specific embodiments.

[0010] 1. Lot arrangement

[0011] Before plowing the land, remove stones and other sundries on the ground. After the weeds turn green, spray the ground with a kill-type herbicide. One week later, when all the plants are obviously injured, use a heavy rake to rake the land in a criss-cross pattern. Apply granule insecticide to eliminate pests in the soil, and apply decomposed organic fertilizer 15000~20000kg / hm 2 Or compound fertilizer 150~225kg / hm 2 Use it as a base fertilizer, and then use a rotary tiller to rake and level the soil so that the base fertilizer is mixed with the finely divided soil.

[0012] 2. Site conditions

[0013] 1) The most suitable area for seed production: temperate to cold temperate areas at an altitude of 2600m to 4500m;

[0014] 2) Soil: meadow soil, the soil particle size is required to be 0.2~0.4cm when sowing;

[0015] 3) Temperature:...

Abstract

The invention discloses a method for improving elymus nutans griseb seed yield in Aba county. The method includes the following steps: (1) clearing up land masses; (2) processing seeds; (3) sowing time; (4) sowing mode and quantity; (5) field management and (6) harvesting in the mature period in the last ten days in the August. The optimum sowing time is May and the middle ten days of June at the latest, and sowing can be conducted when soil temperature is stabilized to be over 8 DEG C. The sowing mode is strip sowing, and the row distance is 40cm-60cm. The sowing quantity is 122.5-30kg/hm<2>, and the sowing depth is 1cm-2cm when the seed true value is 100%. Soil is covered on the seeds to press the seeds after sowing. Additional fertilizer is not required in the year of sowing, or a small quantity of compound fertilizer can be additionally utilized. The compound fertilizer is additionally applied in tillering jointing stage in the next year, and simultaneously fertilizers including proper calcium, molybdenum, manganese and other trace elements can be applied in the flowering and pustulation periods. The method adopts the sowing and field management technology, resolves the problem that the elymus nutans griseb in the Aba county is low in emergence rate, strong in seed holding performance and low in seed output, greatly improves emergence survival rate, maturing rate and seed yield, and provides technological support and guarantee for large scale application and dissemination in the Qinhai-Tibet plateau section in our country.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for increasing seed yield of Elymus aba. Background technique [0002] Elymus nutans Griseb., also known as Elymus nutans Griseb., is a perennial herbaceous plant of the genus Elymus nutans in the family of Gramineae. Elymus weeping is distributed in Tibet, Northwest China, North China and other places in my country, the Asian part of the former Soviet Union, and the Himalayas of India. It is often used as a constructive species in alpine grasslands on the Qinghai-Tibet Plateau at an altitude of 2500-4500m, and its habitats are beaches and valleys. , Shady foothills to shrub meadows and alpine meadows. Elymus acarina has a wide range of plasticity, strong adaptability, cold resistance, drought resistance, high crude protein content, good palatability, and easy cultivation. The grass is soft, easy to prepare hay, and horses, cattle, and sheep like to eat it. It ca...
