Problems solved by technology

[0007] According to the problems existing in the continuous cropping of Huanghuai cotton and peanut production areas, the present invention provides a grain-vegetable-cotton-oil compound high-efficiency planting method in annual strips, which is beneficial to the ventilation and light transmission of wheat and cotton, and exerts the marginal effect of high-stalk crops to solve the problem. Issues such as obstacles to continuous cropping in cotton and flower growing seasons

Embodiment 1

[0028] In the autumn of 2012, the experimental planting began in Jiangzhuang Village, Liangcun Town, Gaotang County, Shandong Province, with an area of ​​5 mu.

[0029] (1) The width is 5.1 meters, which is divided into two equal widths of 2.55 meters. Spinach and wheat are sown in equal widths in the middle and early October. ) 50 kg / mu, slow-release nitrogen fertilizer 20 kg / mu.

[0030] In the above-mentioned planting method, for the convenience of mechanized operation, 12 rows of wheat are sown with equal row spacing, and the row spacing is 18-20cm. Spinach spread.

[0031] (2) Harvest spinach from late March to early April in the second year, sow cotton in mid-to-late April, and apply 40 kg / mu of compound fertilizer (15-15-15) before rotary tillage; Sow summer peanuts, and apply compound fertilizer (15-15-15) 50 kg / mu before rotary tillage. In mid-to-early October, wheat is sown after cotton is harvested, and spinach is sown after peanuts are harvested.

[0032] In th...

Embodiment 2

[0045] As above, in order to further verify the effect, a test planting was also carried out in Xijiangtang Village, Liangcun Town, Gaotang County, Shandong Province in 2012, with an area of ​​4 mu.

[0046] The total yield of wheat, cotton and peanuts under inter-cropping rotation is also higher than that of single cropping in the same area, among which the yields of wheat and cotton increased significantly, while the yields of peanuts decreased slightly. From the perspective of the occurrence of diseases and insect pests, the annual rotation cropping wheat, cotton and peanut had a significantly lower diseased leaf rate than single cropping, wheat and cotton were also the most obvious; the insect population density of the three crops annual rotation cropping was lower than that of single cropping, wheat and cotton Cotton is also most notable. It shows that annual crop rotation is beneficial to the ventilation and light transmission of tall crops, giving full play to the advan...

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to an annual zonal composite efficient planting method of grain / vegetable-oil / cotton. According to the method, based on the complementary characteristics of high and low crops such as wheat / spinach and peanut / cotton, optothermal and other resources are fully utilized, so that ventilation and light transmitting of the wheat and cotton are facilitated, the marginal effect of high-pole crops is exerted, simultaneous planting of two crops and annual planting of four crops are achieved, and the growth of various crops is promoted. By adopting a grain / vegetable-oil / cotton planting mode, long-term continuous cropping obstacles of single crops such as the cotton and the peanut are alleviated, annual crop rotation and alternate husbandry are achieved, soil fertility improvement is facilitated, the occurrence of diseases and insect pests of single crop planting is reduced, the application of fertilizers and pesticides is reduced, the eco-environmental quality is improved, and the agricultural sustainable development is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a band-shaped compound high-efficiency planting method for grain, vegetables, oil, and cotton. Background technique [0002] Continuous cropping obstacle refers to the abnormal growth and development of crops caused by continuous cultivation of the same crop or related crops on the same soil. Symptoms are generally poor growth and development, decreased yield and quality, and in extreme cases, local dead seedlings, no seedlings or vigorous seedlings; most of the affected plants have browning, reduced branches, low vigor, and narrow distribution range, resulting in water absorption. , The capacity of nutrients is reduced. Obstacles are generally obvious in the initial stage of growth, and can often be recovered to varying degrees in the later stage. There are significant differences in continuous cropping obstacles among plant families and genera. The crops tha...
