Embodiment 1

[0022] In 2012 and 2013, at the alfalfa seed production base in Luqiong Township, Naidong County, Shannan Prefecture, Tibet, Zhonglan No. 1 alfalfa was used as the experimental material, and effective trace elements boron, manganese and conventional fertilizer ZnSO were sprayed at the flowering stage of Zhonglan No. 1 alfalfa 4 , FeSO 4 、KH 2 PO 4 、KNO 3 , spraying through the combination of different fertilizers, and the spraying area of ​​each combination is 30m 2 , set 3 repetitions. Combination M1: boron fertilizer\manganese fertilizer\KH 2 PO 4 , combination M2: boron fertilizer \ manganese fertilizer \ ZnSO 4 \FeSO 4 , combination M3: boron fertilizer \ manganese fertilizer \ KNO 3 , combination M4: manganese fertilizer, combination M5: boron fertilizer \ manganese fertilizer \ ZnSO 4 \FeSO 4 \KH 2 PO 4 \KNO 3 , Combination M6: boron fertilizer \ manganese fertilizer. Wherein, manganese fertilizer concentration (mass percentage): 0.1%; Boron fertilizer conc...

Embodiment 2

[0031] In 2013, at the alfalfa seed production base in Luqiong Township, Naidong County, Shannan District, Tibet, Zhonglan No. 1 alfalfa was used as the experimental material, and effective trace elements boron and manganese were sprayed on Zhonglan No. 1 alfalfa at the flowering stage. Spraying amount experiment, the spraying area of ​​each combination is 30m 2 , set 3 repetitions. The concentration combination is shown in Table 3.

Abstract

The invention relates to a micro-fertilizer composition for improving the yield of alfalfa seeds in the "one river and two rivers" area of ​​Tibet, which is prepared from the following components in parts by weight: 18 parts of boron fertilizer and 15 parts of manganese fertilizer. The invention also provides a method for using the micro-fertilizer composition, through controlling the spraying ratio and spraying time of the micro-fertilizer composition, the pollen germination is promoted, the pod setting rate is increased, and the purpose of high yield is achieved. The seed yield of spraying the micro-fertilizer treatment of the present invention is increased by more than 70% compared with the control, which is significantly higher than the control.

Description

technical field [0001] The invention relates to the field of plant nutrition, in particular to a micro-fertilizer composition for improving the yield of alfalfa seeds in the "one river and two rivers" area of ​​Tibet and its application method. Background technique [0002] The "one river and two rivers" area in Tibet is the most important agricultural and animal husbandry industry area in Tibet. It is 3500-4200m above sea level and has good heat conditions. It belongs to the plateau temperate zone semi-arid monsoon climate. The annual average temperature is about 7.5℃; More than 100% of the rainfall is concentrated in June to September. [0003] According to "Introduction to Agriculture in Tibet", the yield of alfalfa seeds in Tibet is 10-20kg / mu, which is far lower than the yield of 15-60kg / mu in Gansu, and the amount of harvested seeds obviously cannot reach the economic harvest. The factors affecting the seed production of Tibetan alfalfa were analyzed, which were mainl...
