Problems solved by technology

[0006] In view of the current Timothy planting and production process in northern my country and Northeast China, the planting methods are not standardized and the management is not in place, so that the survival of the plants overwintering is low, and it is easy to cause large areas of death after turning green, which eventually leads to the failure of Timothy forage production. Problem, the present invention provides a kind of planting method that improves the overwintering rate of Timothy in cold regions

Embodiment 1

[0035] Embodiment 1 Timothy grass planting in Bashang area, Hebei Province

[0036] Guyuan County, Hebei Province is located on the Bashang Plateau, where the extreme temperature in winter can reach below -35°C. From 2000 to 2001, Timothy was planted twice before and after, all using the flat sowing method, that is, after land consolidation, no ditching , directly use 2-4 rows of seeders to sow, the depth is 3-5cm, the sowing rate is 0.5kg / mu, and there is no sowing fertilizer when sowing, and only irrigate once after sowing, and do not carry out when freezing before winter and after turning green Fertilization and irrigation, with a total area of ​​3,000 mu, failed because the plants failed to survive the winter and turn green.

[0037]In 2002, 100 mu of Timothy was planted in Guyuan Pasture in Bashang, Hebei by applying the technical solution of the present invention. Before planting, first clean up the front stubble crops on the ground, then plow the soil 22cm deep with a ...

Embodiment 2

[0038] Embodiment 2 Timothy grass planting in Inner Mongolia Hailar area

[0039] Hailaer City, Inner Mongolia Autonomous Region is located in the northeast of my country, in the northwest of Heilongjiang Province. The extreme temperature in winter is below -40°C. During 2011-2013, Timothy was planted. , without ditching, the sowing rate is 1.0kg / mu, the sowing depth is only 3cm, the row spacing is 15cm, and there is no sowing fertilizer when sowing, no irrigation conditions after sowing, and no corresponding fertilization measures, but the overwintering rate is still less than 30%. .

[0040] In 2014, Hailaerte Nihe Ranch used this invented technology to plant 100 mu of timothy grass. Before sowing, the land was sorted out first, and the front stubble of rapeseed on the ground was cleaned up. Then the tractor was equipped with a five-share plow to plow the soil 22cm deep, and the residual root system of the soil was removed, and the rotary tillage was used. The machine belt wi...

Embodiment 3

[0041] Embodiment 3 Timothy grass planting in Yanqing area, Beijing

[0042] Yanqing County, Beijing is located in the northwest of Beijing. Although it belongs to the continental monsoon climate zone, it is a temperate and middle temperate zone, a semi-arid and semi-humid transitional zone, but it is affected by the geographical influence of the Yanshan Mountains and Jundu Mountains. In winter, it is mainly affected by the dry and cold air in the northwest. Controlling, scarce precipitation, large temperature difference between day and night, and extreme temperature in winter can reach below -15°C. During 2004-2007, during the renovation and reuse of wasteland, after land consolidation, artificial sowing was carried out directly without ditching, and the seeding rate was 1.0 kg / mu, the depth is 5cm, the row spacing is 45cm, and there is no sowing fertilizer when sowing. After sowing, because there is no irrigation condition and no fertilization, the overwintering rate of sowin...

Abstract

The invention relates to a planting method for increasing the wintering rate of timothy grass in a cold region. The planting method includes the following steps of sowing, wherein soil preparation, deep ditching sowing, shallow covering after sowing and sowing fertilizer application are conducted; cutting and fertilizer application, wherein cutting is not conducted in the sowing year, and fertilizer is applied just one month before local first frost; irrigation, wherein if the manual irrigation requirement is met, irrigation is conducted once after each fertilizer application, frozen water and regreening water are irrigated when the winter daily average temperature is lower than zero DEG C and after spring regreening respectively, and if the manual irrigation requirement is not met, natural rainfall is used for irrigation. Timothy grass is planted in the north of China, the plant wintering rate is increased to 95% or more from the original value smaller than 35%, the effect is remarkable, and the technical bottleneck of difficult wintering in large-scale cultivation popularization of timothy grass in the north and even northeast region of China is broken through successfully.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a planting method for increasing the overwintering rate of timothy in cold regions. Background technique [0002] Timothy (Phleumpretense L.) is a semi-winter perennial herbaceous plant belonging to the grass family Timothy. It is native to Eurasia and brought to the United States by early immigrants from New England. Now it is mainly distributed in eastern Canada, Hokkaido, Japan, and northern Australia. , the United States, Russia, Western and Northern Europe. Timothy likes a cool and humid climate, and is mainly distributed between 40°-50° north latitude. There are about 10 species of Timothy in the world, and there are 4 wild species in my country. Among them, Timothy is the most widely cultivated in all countries in the world. Timothy (Phleumpretense L.) of the genus. Timothy has a long life span and can generally be used for 5-7 years. It has delicate leaves, high grass yield...
