Embodiment 1

[0022] Embodiment 1: interplanting cotton variety selection test

[0023] Cotton varieties used in production in the Dongting Lake area and some representative local varieties were selected for interplanting with cowpea, and a variety screening test was carried out. Cowpea is sown in a timely manner and transplanted in late March; cotton is transplanted one week before the harvest of cowpea in early and mid-June, from May 30 to June 10; cowpea is transplanted in wide rows covered with ridges and open boxes. , the width of the compartment is 180cm, and the frame is planted with 2 rows of cowpea, the width of the row is 140cm, the distance between the holes is 40cm, 3-4 seeds are sown in each hole, and the seedlings of the two plants can be staggered to ensure ventilation and light in the field; when transplanting cotton, cowpea 2 rows of cotton are planted in wide rows, the spacing between cotton rows is 60cm, the spacing between cotton plants is 40cm, the row spacing between c...

Embodiment 2

[0027] Embodiment 2: interplanting cotton transplanting period selection test

[0028] 4 cotton varieties that are suitable for interplanting with cowpea in the Dongting Lake area are selected in Example 1: Xiangzamian No. 21, Xiangzamian No. 22, Datang No. 6 and Xiangza 008, and carry out interplanting cotton transplanting period selection test , 2 weeks before cowpea harvest (May 30), 1 week before harvest (June 8), after picking (June 15), 1 week after harvest (June 22), and after harvest 2 weeks (June 29) and 5 periods were transplanted. Cowpeas are transplanted in wide rows covered with mulch and mulched in open compartments. The width of the compartment is 180cm, and two rows of cowpeas are planted on a frame with a width of 140cm and a hole spacing of 40cm. Row cotton, the cotton row spacing is 60cm, the cotton plant spacing is 40cm, the cowpea and cotton row spacing is 40cm, and the cotton transplanting density is 1100-1200 plants per mu; manual drilling is adopted, a...

Embodiment 3

[0032] Embodiment 3: Cotton planting density and row spacing of cowpea cover test on the impact of cotton yield

[0033]Cotton variety Xiangzamian No. 21 suitable for cowpea intercropping that was screened in Example 1 was used as material, and a two-factor split-plot design was used to test in Xinhe Township, Huarong County, Huarong County, Dongting Lake Cotton District, Hunan Province and Wushenggong Town, Nanxian County. Cowpeas are sown in good time to raise seedlings, and transplanted in late March; cotton is transplanted one week before the harvest of the cowpeas and when the cowpeas are picked; The width of the row is 140cm, the hole distance is 40cm, 3-4 seeds are sown in each hole, and the seedlings of the two plants can be kept. Cowpea can be staggered sowing to ensure the ventilation and light transmission in the field; 40cm, when the distance between cowpea and cotton rows is 40cm, 25cm, and 15cm respectively, the effect of planting 2 rows, 3 rows, and 4 rows of co...

Abstract

The invention belongs to the technical field of crop culture, and discloses a three-dimensional culture method for interplanting cotton in cowpea in a Dongting Lake area. According to the method, seeding and seedling culture of the cowpea are carried out in early March in each year, ridge forming, furrowing, earth film covering and wide line transplanting are carried out in late March, the furrow surface width is 180cm, two lines of cowpea are planted in a frame erecting way, the line width is 140 cm, and the pit distance is 40cm; the nutrition pot seeding and seedling culture of cotton are carried out at late April to early May, transplanting is carried out in late May to early June, two lines of cotton are planted in the wide lines of the cowpea, manual hole forming and staggered pit transplanting are carried out, and the plant distance is 40cm. The differences of the frame erected cowpea and the cotton in the time niches and the space niches of light, heat, water and fertilizers are used, the cotton is interplanted in the cowpea, the light and heat resources are efficiently used, the time and space complementation utilization of the cowpea and the cotton on the resources is realized, a season of cowpea is additionally planted in the Dongting Lake cotton area, high yield and high quality of the cotton are promoted, the resource utilization efficiency and the land productivity are improved, the crop economic yield of the whole year crops is increased, the interannual crop rotation in the zone is realized, and the insect pest of the cotton and the cowpea is reduced.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a three-dimensional cultivation method for cowpea interplanting cotton in the Dongting Lake area. Background technique [0002] Intercropping refers to the planting method of sowing or transplanting the next season crops between rows in the late growth period of the previous season crops, also called intercropping. Compared with single cropping, it can not only make full use of space in stages, but more importantly, it can prolong the use of the growing season of off-season crops, increase the multiple cropping index, and increase the total annual crop output. It is a planting method that intensively uses time and space. [0003] Cowpea is an annual twining herbaceous plant. It is one of the main high-protein legume vegetables in my country. Its stems grow vigorously, and it is necessary to build supports for cultivation. The pods are between 20-90cm long, t...
