Embodiment 1

[0021] Example 1: In 2015, the altitude of Qinghai Provincial Minhe Hui and Tu Nationality Autonomous County in the Qinghai-Tibet Plateau was 1740m.

[0022] Mixed sowing varieties: Qingyin No. 1 oats, arrowhead peas

[0023] Mixed sowing ratio: mix oats and arrowhead peas according to the mixed sowing ratio of 7:3, specifically: oats 157.5kg / hm 2 , Arrowhead pea seeding rate 67.5kg / hm 2 .

[0024] Sowing time: Sowing in April and May to build artificial grassland.

[0025] Sowing method: Before sowing, carry out cultivation and management measures such as deep plowing, leveling, and weeding on the sowing land. Adopt manual drilling, the row spacing is 10cm, and the sowing depth is 3.5cm. The forage seeds of oats and arrowhead peas are evenly mixed and directly sown.

[0026] Cutting and utilization: When the oats grow to the earing stage, the height of the stubble is 5cm and mixed harvesting and cutting.

Embodiment 2

[0027] Example 2: 2080m above sea level in Minhe Hui and Tu Autonomous County of Qinghai Province in Qinghai-Tibet Plateau in 2015

[0028] Mixed sowing varieties: Qingyin No. 1 oats, arrowhead peas

[0029] Mixed sowing ratio: mix oats and arrowhead peas according to the mixed sowing ratio of 6.41:3.58, specifically: oats 135kg / hm 2 , Arrowhead pea seeding rate 75.4kg / hm 2 .

[0030] Sowing time: Sowing in April and May to build artificial grassland.

[0031] Sowing method: Before sowing, carry out cultivation and management measures such as deep plowing, leveling, and weeding on the sowing land. Artificial drilling is adopted, the row spacing is 13.8cm, and the sowing depth is 4cm. The forage seeds of oats and arrowhead peas are evenly mixed and directly sown.

[0032] Cutting and utilization: When the oats grow to the earing stage, the height of the stubble is 5cm and mixed harvesting and cutting.

Embodiment 3

[0033] Example 3: In 2015, the altitude of Huangzhong County, Qinghai Province, Qinghai-Tibet Plateau was 2562m

[0034] Mixed sowing varieties: Qingyin No. 1 oats, arrowhead peas

[0035] Mixed sowing ratio: mix oats and arrowhead peas according to the mixed sowing ratio of 5.58:4.42, specifically: oats 180kg / hm 2 , Arrowhead pea seeding rate 143kg / hm 2 .

[0036] Sowing time: Sowing in April and May to build artificial grassland.

[0037] Sowing method: Before sowing, carry out cultivation and management measures such as deep plowing, leveling, and weeding on the sowing land. Adopt manual drilling, the row spacing is 17cm, and the sowing depth is 5cm. The forage seeds of oats and arrowhead peas are evenly mixed and directly sown.

[0038] Cutting and utilization: When the oats grow to the earing stage, the height of the stubble is 5cm and mixed harvesting and cutting.

Abstract

The invention discloses a mixed seeding and plants building method of oats and common vetches in different altitude areas of Qinghai-Tibet Plateau. The method includes steps of a), preparing the seeding land before seeding; applying artificial strip seeding, wherein seeding line space is L meter, the seeding depth is h meter, and the altitude of the seeding land is Hb meter; the numerical values of the seeding line space and the seeding depth can meet the range below: L is more than Hb / 20000 and less than Hb / 15000, and h is more than (Hb / 160000+2) and less than (Hb / 80000+2); b), mixed-seedingand planting oats and common vetches, wherein the numerical value K of the pasture seed mixing ratio of the oats and the common vetches meets the formula K=(5800-Hb) / Hb, wherein Hb is the altitude ofthe seeding land. The mixed seeding and plants building method has the advantages of mixed-seeding and planting oats and common vetches at suitable ratio according to the ecological conditions of different altitudes, thus the pasture output is improved, and the nutrition value and the palatability of the pasture are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pasture mixed sowing and planting, in particular to a method for establishing the mixed sowing of oats and arrowhead peas in areas of different altitudes on the Qinghai-Tibet Plateau. Background technique [0002] The Qinghai-Tibet Plateau is one of the five major pastoral areas in my country, with a vast territory and high altitude. Under the influence of the unique geographical environment and climatic conditions, the climate is cold and dry, the annual accumulated temperature is low, the ecological environment is fragile, the pasture growing season is short, the cold season lasts for 7 to 8 months, and the primary productivity of the grassland is low. The three-month dry grass season is difficult to meet the nutritional needs of grazing livestock, which makes the contradiction between grassland and livestock serious, which seriously restricts the balanced and stable development of grassland animal husb...
