Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with specific embodiments.

[0026] 1. Lot arrangement

[0027] The sowing plot should be deeply plowed in autumn. 20 days before sowing, use a herbicide to remove all green plants in the plot and kill pests in the soil. After one week, plow the land with a plow to a depth of 18cm to 20cm. Combined with soil preparation, apply compound fertilizer 600kg / hm 2 Make base fertilizer. Before planting, harrow again to make the soil surface level and the soil finely divided.

[0028] 2. Site conditions

[0029] 1) The most suitable area for seed production: it can grow in temperate to cold temperate regions at an altitude of 2800m to 3600m;

[0030] 2) Soil: meadow soil, the soil particle size is required to be 0.2cm when sowing;

[0031] 3) Temperature: The suitable temperature for germination of seeds is 8°C to 12°C, and the accumulated temperature from turning green to maturity is 1500°C to 2000°C....

Abstract

The invention discloses a method for improving yield of Sichuan glass lead No.3 phalaris seeds. The method includes the following steps: A1, fielding plot readjustment; A2, site condition; A3, seeding time; A4, seeding method and seeding rate; and A5, field management. The seeds are harvested at mature period of the last ten-day of August. The method adopts a seeding and field management technique, solves the problem that sichuan glass lead No.3 phalaris is low in maturing rate, low in seedling emergence rate, difficult in reproduction and the like, greatly improves seedling emergence survival rate, maturing rate and seed yield, and provides technical support and guarantee for large-scale popularization and application of the phalaris at qinghai-tibet plateau area in our country.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for increasing the seed yield of Chuancaoyin No. 3 Lilygrass. Background technique [0002] "Chuan Cao Yin No. 3" was born in the United States and was introduced to Hongyuan County, Aba Prefecture, Sichuan Province in 1979. Introduced and domesticated at the Hongyuan Breeding Test Base of Sichuan Grassland Science Research Institute, and successively carried out regional and production tests in Damxung County, Tibet, Daofu County, Ganzi Prefecture, Kangding County and Maoxian County, Aba Prefecture. In 2007, it passed the national grassland test. Approved by the Variety Approval Committee, it was officially named "Chuancaoyin No. 3" Licao. This variety is perennial and sparse bushy, tall grass. The rhizome is thick and developed, with many tillers, the stem is thick and round, often solitary or a few in clusters, erect, smooth and glabrous, up to 150cm high. Th...
