Problems solved by technology

[0003] The existing breeding of new peanut varieties is basically carried out in the field, and the field breeding is greatly affected by the natural environmental conditions. Generally, the selected varieties need to be sprayed with plant growth regulators in production to control the vigorous growth of peanuts. It is more difficult to control the vigorous growth when there is a lot of fertilization, which will cause lodging, which will not only cause a large reduction in production, but also not conducive to mechanized harvesting

Embodiment 1

[0031] Peanuts are planted with a plant spacing of 20cm and a row spacing of 40cm. Shade the peanuts for 7 days during the flowering stage of the peanuts, and use a sunshade net for shading. The light transmittance of the sunshade net is 50%. While shading, a total of 300kg / hm of pure nitrogen is sprayed 2 , pure nitrogen is sprayed with 0.5% urea aqueous solution by mass percentage, and then sprayed with water to keep the moisture content of the soil for planting peanuts not less than 75%;

[0032] Shade the peanuts for 9 days at the needle-setting stage, using a sunshade net with a light transmittance of 50%. While shading, spray a total of 300kg / hm of pure nitrogen 2 , pure nitrogen is sprayed with 0.5% urea aqueous solution by mass percentage, and then sprayed with water to keep the moisture content of the soil for planting peanuts not less than 75%;

Abstract

The invention provides a method for breeding green efficient peanut varieties, and belongs to the technical field of agricultural planting. The method comprises the steps that shading is conducted for6-8 d in the peak flowering stage of peanuts, 280-320 kg / hm<2> of pure nitrogen is applied, and then water is sprayed to the surfaces of peanut leaves after applying pure nitrogen; shading is conducted for 8-10 d at the pegging stage of the peanuts, 280-320 kg / hm<2> of pure nitrogen is applied, and then water is sprayed to the surfaces of the peanut leaves after applying pure nitrogen; shading isconducted in the pod bearing period for 10-12 d, 200-250 kg / hm<2> of pure nitrogen is applied, water is sprayed to the surfaces of the peanut leaves after applying pure nitrogen; peanut plants not higher than 40 cm in the planing period are bred as green efficient peanut varieties. According to the method for breeding the green efficient peanut varieties, the plant height of the varieties in theplanting period is lower than 40 cm, a plant growth regulator does not need to be sprayed to control growth of the peanuts, lodging and yield reduction do not occur, not only is use of the plant growth regulator reduced, but also the economic coefficient of the peanuts is increased, and green and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for breeding green and high-efficiency peanut varieties. Background technique [0002] In my country's peanut production, the plant height of the currently popular peanut varieties is above 40 cm. During the growth period, it is generally necessary to spray 2-3 times of plant growth regulators to control the vigorous growth of peanuts, so as to ensure that peanuts do not fall down and reduce production and facilitate mechanized harvesting. [0003] The existing breeding of new peanut varieties is basically carried out in the field, and the field breeding is greatly affected by the natural environmental conditions. Generally, the selected varieties need to be sprayed with plant growth regulators in production to control the vigorous growth of peanuts. It is more difficult to control the vigorous growth when there is more fertilization and a little more ferti...
