Qinghai-Tibet plateau high-cold pasturing area greenhouse grass planting technology

Abstract

The invention discloses Qinghai-Tibet plateau high-cold pasturing area greenhouse pasture planting technology which comprises the following steps: (1) a greenhouse is prepared; (2) grass seeds and base fertilizers are respectively mixed standby; (3) ploughed fallowing is carried out; (4) preparation before broadcast sowing and planting is carried out; (5) a ditching method is prepared; (6) sowing is carried out; (7) soil is covered manually and smoothed, and manual suppression is carried out; (8) preparation before a rainy season comes is carried out; (9) treatment of 7-8 months at a high temperature is carried out; and (10) mowing and overwintering treatment are carried out. The Qinghai-Tibet plateau high-cold pasturing area greenhouse pasture planting technology integrates annual grass cultivation, perennial grass cultivation and cold season-warm season grass cultivation, is strong in flexibility and adaptability, simple, easy to operate, and low in cost, is the technology which is popularized and used by nations and local residents, provides a technological approach for forage grass production of extreme high altitude areas in China, and provides technological support for grass supply.

Description

technical field [0001] The invention relates to a planting technology, in particular to a greenhouse herbage planting technology in the alpine pastoral area of ​​the Qinghai-Tibet Plateau. Background technique [0002] The contradiction between grassland and livestock has long been a bottleneck in the development of grassland animal husbandry in the Qinghai-Tibet Plateau. In the alpine pastoral areas of Tibet, the natural grassland and artificial forage grassland can only feed 8.5 million yaks each year, and about 6.5 million yaks lack feed. The reason is that the livestock raised in the Qinghai-Tibet Plateau area does not have enough forage and feed, resulting in a large number of livestock dying in the cold season and heavy snow season, and the loss of herdsmen is huge. At the same time, in order to make up for the loss of livestock, herdsmen raise a large number of livestock, and the relationship between livestock and feed has been in a distorted state for a long time. ...

AI Technical Summary

Problems solved by technology

Due to climate restrictions in alpine regions, it is very difficult to carry out artificial forage work. The main reasons are: (1) The low temperature climate makes forage growth and overwintering difficult, and artificially planted forage can only grow for 2-3 months (2) The high water evaporation rate makes the artificial forage land lack enough water to maintain the growth of forage; (3) The drastic temperature change makes it difficult for legume forage to attract enough pollinators in the open air; (4 ) Most of the natural grasslands are reclaimed into artificial forage fields, and the management is insufficient, resulting in grassland abandonment, degradation, and even soil erosion and ecological disasters
