Problems solved by technology

It takes about 5 years to breed a spring soybean variety by planting two crops a year in spring soybeans in Guangxi, and it takes at least 4 years to construct a recombinant inbred line from hybridization to F7 generation, and sometimes the new line will grow in autumn. The amount of seeds is small, which affects the promotion of new varieties in the second year

Embodiment 1

[0020] In Guangxi and Hainan Province, the method of three crops in one year is utilized to carry out the breeding of spring soybean hybrid progeny material:

[0021] Sow parental materials (Guichun No. 1, Guichundou 103, Guichundou 104, Guichundou 6, Guichun 8, Guichun 1, Guizao 2, etc.) in spring (mid-March) with a row spacing of 40 cm, the spacing between plants is 10 cm, and 1 seedling per hole. Before sowing, the land is leveled and drilled, and 15 kg / mu of nitrogen, phosphorus and potassium ternary compound fertilizer is used as the base fertilizer. After sowing, use Jinduer (96% emulsifiable oil) to seal at 100 ml / acre. Use 500 ml of cypermethrin to 500 kg of water and 50 ml / mu of Lesben to prevent and control insect pests during the pest infestation period. Configure hybrid combinations in full flowering stage. Carry out conventional field management such as intertillage, soil cultivation, weeding, irrigation, etc. according to the field management method, and harves...

Embodiment 2

[0025] Utilize the method of the present invention three crops a year to carry out the construction of recombinant inbred line in Guangxi and Hainan province:

[0026] In spring (mid-March) sow parental materials (Gantai-2-2, Wan 82-178, Biaojiaozao, Qipeihua, Gongdou No. 7, Zhizidou), the row spacing is 40 cm, the plant spacing is 10 cm, and each hole is 1 For seedlings, level the land before planting and then drill in rows, using 15 kg / mu of nitrogen, phosphorus and potassium ternary compound fertilizer as the base fertilizer. After sowing, use Jinduer (96% emulsifiable oil) to seal at 100 ml / acre. Insect pest control with cypermethrin and rospen during infestation period. Configure hybrid combinations in full flowering stage. Carry out conventional field management such as intertillage, soil cultivation, weeding, irrigation, etc. according to field management methods, and harvest hybrids in time after soybeans mature. In autumn (mid-July), sow the parents and hybrids (Ca...

Embodiment 3

[0030] Utilize the method of three crops a year of the present invention in Guangxi and Hainan to carry out the propagation of new line:

[0031]Select new strains (Guichundou 106 and Guichundou 108) with a growth period of 90-100 days, sow in spring (mid-March), with a row spacing of 40 cm, a plant spacing of 10 cm, and 1 seedling per hole. Drill sowing was carried out, and 15 kg / mu of nitrogen, phosphorus and potassium ternary compound fertilizer was used as the base fertilizer. After sowing, use Jinduer (96% emulsifiable oil) to seal at 100 ml / acre. Insect pest control with cypermethrin and rospen during infestation period. Configure hybrid combinations in full flowering stage. Carry out conventional field management such as intertillage, soil cultivation, weeding, irrigation, etc. according to the field management method, and harvest hybrids in time after soybeans mature in late June. Autumn (mid-July) sowing and multiplication, row spacing 40 cm, plant spacing 6 cm, 2 ...

Abstract

The invention belongs to the technical field of spring soybean cultivation and in particular provides a rapid generation adding method for triple cropping of spring soybean filial generation. The rapid generation adding method contains the following steps: selecting varieties; sowing; carrying out weed control; carrying out water and fertilizer management; carrying out pest control; harvesting; preferably selecting the varieties, namely the spring soybean filial generation in a growth period of 90-100 days, preferably sowing in Hainan province and Nanning of Guangxi, carrying out spring sowingin the middle ten days of March, and harvesting in the last ten days of June; carrying out autumn sowing in the middle ten days of July, and harvesting in the middle ten days of October; and carryingout winter sowing in the middle ten days of November, and harvesting in the last ten days of February the next year. The rapid generation adding method provided by the invention not only can shortenbreeding time and improve working efficiency but also can promote propagation of fine varieties and lines, and popularization of new strains is accelerated.

Description

technical field [0001] The invention belongs to the technical field of spring soybean planting, and in particular relates to a method for quickly adding three crops a year to hybrid offspring of spring soybean. Background technique [0002] Soybean is the main grain and oil crop in my country, and plays a pivotal role in people's life and national economy. Guangxi is one of the provinces (regions) with a large soybean planting area in southern my country. Soybean is not only a food crop but also an economic crop in Guangxi. Its area and output are second only to corn among dry grain crops. The soybean breeding period is longer, and it generally takes about 10 years to breed a soybean variety. At present, spring soybeans in Guangxi mainly adopt the planting mode of spring sowing and autumn sowing twice a year. Under this mode, spring sowing is sown in early March and harvested in mid-June. After sowing in early March, cold air is often encountered, and the weather is cold. ...
