Problems solved by technology

[0006] The complexity of the autumn climate in the coastal areas of South China, coupled with the high multiple cropping index of vegetable bases, the decrease of soil humus and the increase of physiological barriers, often cause vegetable diseases, especially soil-borne diseases, to be prevalent, causing a large number of vegetable crops to die, seriously affecting yield and quality , has become one of the main bottlenecks restricting the sustainable development of vegetable production in vegetable bases in the coastal areas of South China
In addition, some farmers are accustomed to "planting white seeds" (without applying basal fertilizer), resulting in the fact that subsequent top dressing cannot make up for the damage to the plants

Embodiment 1

[0035] 1. Arrangement of cropping period

[0036] Cowpea seeds were broadcast live in early September, harvested in late October and ended in late December;

[0037] 2. Select suitable long cowpea varieties:

[0038] It is advisable to choose varieties with strong growth vigor, high pod setting rate, high yield, good commerciality, and storage and transportation resistance; Nongfeng No. 9 cowpea variety is mid-late maturing, strong growth vigor, high pod setting rate, pod length 60-70cm, pod transverse diameter 0.8cm, single pod weight 20-30g, green and white pods, long round pods, well-proportioned pods, smooth and shiny pod surface, good commodity, storage and transportation; planted in coastal areas of South China, 55 days from autumn sowing to first harvest, The output is 2500-3500kg / mu, the field has strong resistance to rust, fusarium wilt, and coal mold, and the comprehensive characteristics of the variety meet the requirements for planting in the open field of autumn ...

[0050] Example 2 : Comparison of Yield and Characters of Different Varieties

[0051] In 2018 and 2019, the Vegetable Bean Research Team of the Vegetable Research Institute of Guangxi Academy of Agricultural Sciences worked in Shiwan Town, Hepu County, Beihai City, Guangxi, Qinnan District, Qinzhou City, Guangxi, Liguo Town, Ledong County, Hainan Province, Chengbei Township, Xuwen County, Zhanjiang, Lianshang Town, Shantou City, Guangdong Province and other places carried out regional experiments on the comparison of varieties planted in the open field of autumn leaves. The sowing time of the two-year experiment was the same. It was broadcast live on September 1, harvested on October 22, and ended on December 20. The comparative regional experiment was compared with the local main varieties Jinshuai No. 1 and Yufeng No. 8. , the test plots have a width of 1.5m, using direct seeding, planting in double rows, sowing 3 seeds in each hole, the row spacing is 0.6m, the plant spac...

Abstract

The invention relates to the technical field of asparagus bean cultivation, in particular to an autumn-delay open-field cultivation method for mid-late-maturing asparagus bean varieties in the coastal region of south China. The autumn-delay open-field cultivation method for the mid-late-maturing asparagus bean varieties in the coastal regions of South China comprises the following steps that (1), seed selection is carried out; (2) a base fertilizer is applied; (3), seed disinfection is carried out; (4), sowing and final singling are carried out; (5), vine guiding and pruning are carried out; (6), front control is carried out; (7), post-promoting is carried out; (8), water management is carried out; and (9), pest control is carried out. According to the autumn-delay open-field cultivation method for the mid-late-maturing asparagus bean varieties in the coastal region of south China, the Nongfeng No.9 is selected as the asparagus bean variety according to the actual planting environment condition of the coastal region of south China, and the requirement for high heat resistance of autumn-delay open-field planting is met; and in addition, a front control and post-promoting combined method is adopted in specific cultivation, and the yield and the output value of the asparagus beans are increased.

Description

technical field [0001] The invention relates to the technical field of long cowpea cultivation, in particular to an open-field cultivation method for mid-late-maturing long cowpea variety Qiuyan in coastal areas of South China. Background technique [0002] Long cowpea [Vigna unguiculata W.ssp.sesquipedalis (L.) Verd.] has strong adaptability and wide cultivation range, and is one of the main vegetable species in summer and autumn in my country. In the coastal areas of South China, the cultivation of long cowpea in the autumn extension season has a long history. It adapts to the rainy, high temperature and high humidity growth environment in the autumn extension season of the South China coastal area. The pods are good in commodity and resistant to storage and transportation; , the local autumn extension of cowpea is at the peak of its listing. The growth and harvest of long cowpea in other areas are affected by the cold dew wind, and their growth and harvest are in the fina...
