A planting method for keeping pigeonpea perennial and high yield

Abstract

The invention discloses a planting method for maintain years of high yield of pigeon pea. The method comprises the following steps of 1) sowing seeds and applying fertilizer in late February and earlyMarch; 2) after the seeds are germinated, timely checking, supplementing and thinning the seedlings, performing intertillage weeding once to twice during the seedling period, and mainly applying liquid fertilizer during the seedling period; 3) when the seedlings are 30-50 cm high, performing first pinching, and after every plant grows 4-5 branches, performing second pinching; 4) from the initialflowering period to the initial pod period, applying tri-nutrient compound fertilizer 4.5-5.5 kilograms per mu (=-0.0667 hectares); 5) harvesting peas in October and November; 6) in the following year, till the late March and after the frost period, performing spring pruning to shear the crown into an umbrella shape; 7) harvesting peas in June and July according to standards identical to those ofthe step 5); 8) after the peas are harvested and in late August, performing summer pruning to shear the crown into a flat surface; 9) harvesting peas in October and November, and repeating the steps of 6)-9). The planting method for maintain years of high yield of the pigeon pea can keep perennial habits of the pigeon pea and meanwhile improve the yield, thereby improving the planting level of thepigeon pea and promoting generalization of the pigeon pea.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a planting method for maintaining perennial and high-yield pigeonpea. Background technique [0002] Pigeon pea is a perennial woody plant, which is called tree bean in Taiwan. It is native to India and is an important economic crop in India, East Africa and the Caribbean. Pigeon beans have a relatively large planting area in Taiwan, Guangxi, Yunnan and other places. Although pigeonpea is a perennial plant, due to the limitation of cultivation and management technology, the output of pigeonpea has decreased year by year since the first year of harvest, and the production reduction has reached about 10%. Therefore, at present, the main pigeonpea producing areas in my country including Taiwan Province All adopt the annual planting method, that is, after the planting and harvest of the current year, the plants will be dug out and replanted in the next year. The annual planting...

Problems solved by technology

Although pigeonpea is a perennial plant, due to the limitation of cultivation and management technology, the output of pigeonpea has decreased year by year since the first year of harvest, and the production reduction has reached about 10%. Therefore, at present, the main pigeonpea producing areas in my country including Taiwan Province All adopt the annual planting method, that is, after the planting and harvest of the current year, the plants will be dug up and replanted in the next year.

The annual planting method has the following disadvantages: pigeonpea is planted as an annual, and only one crop can be harvested a year, and it is harvested in autumn. If the cold air comes early, the grain filling will be affected and the grains will not be full enough.

In addition, pigeonpea is a perennial crop. It is planted in the south of my country. Except that it is only harvested once in the year of sowing, it can be harvested twice a year in the future. Now it is planted as an annual, which not only reduces the harvest of one crop every year, but also increases the cost of seeds and sowing labor. , so that the production cost increases
