Embodiment 1

[0019] The method steps of improving arrowhead pea output of the present invention are as follows:

[0020] 1. Sowing and raising seedlings: Arrowhead pea seeds are provided by the Tibet Autonomous Region Seed Company, the variety is "Ximu 333", the sowing date is around April 20 every year, and the sowing rate is 80kg / hm 2 , Drill sowing, the sowing depth is about 5cm, and the row spacing is 25-30cm. Sowing place: Located at the Lhasa Plateau Ecological Experiment Station of the Chinese Academy of Sciences in Lhasa, Tibet Autonomous Region, at 29°41′N, 91°20′E, and an altitude of 3688m.

[0021] 2. Preparation of reagents and spraying methods:

[0022] A. Preparation of chemical reagents: Add 0.67 grams of paclobutrazol (15% wettable powder) per liter of clear water and mix evenly to make a 100 mg / L concentration solution for later use. The molecular formula of paclobutrazol is: (2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)penta-3- alcohol;

Embodiment 2

[0029] Planting place: Located at the Lhasa Plateau Ecological Experiment Station of the Chinese Academy of Sciences in Lhasa, Tibet Autonomous Region, at 29°41′N, 91°20′E, and an altitude of 3688m.

[0030] The difference between the method of this embodiment and embodiment 1 is:

[0031] Preparation of chemical reagents: add 2.68 grams of paclobutrazol (15% wettable powder) per liter of water and mix evenly for later use to make a solution with a concentration of 400 mg / L for later use;

[0032] All the other steps are the same as in Example 1.

[0033] Results: "Ximu 333" matured in early September. Using this method, the average yield of arrowhead pea seeds after harvest was 124.88kg / mu, which was 87.76% higher than that of the control sprayed with water.

Embodiment 3

[0035] The difference between the present embodiment and embodiment 1 is: the seeding rate is 70kg / hm when sowing seedlings 2 , Drill sowing, the sowing depth is about 4cm, and the row spacing is 25-30cm.

[0036] The concentration of paclobutrazol was 200mg / L.

[0037] All the other steps are the same as in Example 1.

Abstract

The invention discloses a method for improving output of common vetch in a high and cold area. The method for improving the output of the common vetch in the high and cold area includes steps of sowing and seedling, preparing growth regulating reagent and spraying reagent, and managing the field. The reagent is multi-effect triazole solution. By means of the method for improving the output of the common vetch in the high and cold area, the output of the common vetch seed is improved by 55-151%; the method for improving the output of the common vetch in the high and cold area provides a provenance source for planting and popularizing the common vetch in large area and is capable of generating good economical benefit.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for increasing the yield of arrowhead peas in alpine regions. Background technique [0002] The Qinghai-Tibet Plateau pastoral area is the main grazing ecosystem and one of the largest grassland systems in China. The area of ​​various natural grasslands in the region is 83 million hectares, accounting for 67% of the land area of ​​the whole region and about 26% of the natural grassland area of ​​China; Some are located in alpine regions. At present, traditional grazing is still the main method for livestock in Tibet. There is an extreme lack of forage in winter and spring, and livestock lose weight seriously, which seriously limits the sustainable development of local animal husbandry. The establishment of high-yield and high-quality artificial grassland plays an important role in alleviating the imbalance of grass and livestock supply in alpine pa...
