Problems solved by technology

The existing cotton interplanting watermelon method (such as CN105830726A) adopts the traditional interplanting mode (one row of watermelon in the middle of two rows of cotton), this method only improves the multiple cropping index of arable land, and cannot take advantage of the synergistic planting of the two

Embodiment 1

[0038] In Zhanhua District, Binzhou City, Shandong Province, I chose a saline-alkali cotton field. The basic situation is: the area is 1.5 hectares, the land is relatively flat, the soil is uniform, and it has good irrigation and drainage conditions. Cotton has been planted for the first three years. The soil fertility of this cotton field is at the upper-middle level, and the multi-point measurement results are average. The total salt content of the plow layer (0-20cm) soil is 0.29%±0.03%, the organic matter is 0.91%, and the alkali-hydrolyzed nitrogen is 31.7mg·kg -1 , Available phosphorus 18.9mg·kg -1 , available potassium 118mg·kg -1 .

[0039] Half of the cotton field (called A1) is planted according to this planting method, and 25-30 days before planting, irrigate 700m2 per hectare 3 Press fresh water and salt, create moisture, and when the soil moisture is suitable (75% to 80% of the maximum water holding capacity of the field soil), evenly spread high-quality soil an...

Embodiment 2

[0055] A saline-alkali cotton field was selected in Huimin County, Binzhou City, Shandong Province. The basic situation is: the area is 2.2 hectares, with good irrigation and drainage conditions, the land is flat, the soil is uniform, and the fertility level is high. Cotton has been planted for the first three years. The cotton field belongs to the superior soil fertility level, and the multi-point measurement results are average. The total salt content of the plow layer (0-20cm) soil is 0.22%±0.05%, the organic matter is 1.07%, and the alkali-hydrolyzed nitrogen is 35.7mg·kg -1 , Available phosphorus 19.7mg·kg -1 , available potassium 122mg·kg -1 .

[0056] Half of the cotton field (referred to as A2) was planted according to this planting method. Cotton was sown on April 17, 2017, watermelon was transplanted on April 26, and cabbage was sown on August 2. Others are the same as in Example 1.

[0057] The other half of the cotton field (referred to as B2) was conventionally...

Embodiment 3

[0060] In Wudi County, Binzhou City, Shandong Province, a high-yielding cotton field was selected on saline-alkali land. The basic situation is: the area is 1.9 hectares, the soil is uniform, and it belongs to a high-fertility level plot. The land is flat and has good irrigation and drainage conditions. Cotton has been planted for the first 2 years. The multi-point measurement results of this cotton field are average, the total salt content of the soil in the plow layer (0-20cm) is 0.20%±0.03%, the organic matter is 1.17%, and the alkali-hydrolyzed nitrogen is 36.9mg·kg -1 , Available phosphorus 19.8mg·kg -1 , available potassium 126mg·kg -1 .

[0061] Half of the cotton fields (referred to as A3) were planted according to this planting method. Cotton was sown on April 18, 2018, watermelon was transplanted on April 29, and cabbage was sown on August 5. Others are the same as in Example 1.

[0062] The other half of the cotton fields (called B3) were planted conventionally, ...

Abstract

The invention discloses a coordinated efficient planting method for cotton, watermelons and Chinese cabbages in a saline-alkaline land. The method comprises the steps: planting zones are covered withmulching films, the cotton and the watermelons are subjected to same-film-zone unified layout, narrow rows of the cotton are subjected to twin-row mulching-film covering, and wide rows are free of mulching-film covering and are exposed ground surfaces; every 5 young cotton plants are alternately spaced sequentially, and 1 row of watermelons are transplanted at the inner side of the same film zoneof sequential-alternate spacing of each cotton row in a misaligned manner; and column-type concentrated fertilizer application is carried out under a middle film of each narrow row, the watermelons are pruned by employing a three-vine-orientated outward pruning method, and the Chinese cabbages are interplanted in the wide rows of the cotton after the watermelons are harvested. According to the method, cotton-watermelon-Chinese cabbage-coordinated-accurate-planting heating, soil moisture preserving and salt suppressing ecological effects on the saline-alkaline land through melon vine, mulchingfilm and Chinese cabbage combined full cover are exerted to the maximum, advantage complementing, early germination and stable growth, high quality and high yield, and coordinated high performance ofthe cotton, the watermelons and the Chinese cabbages in the saline-alkaline land are achieved, the yield of unginned cotton of the cotton is increased by 10.0% or more, the yield of the watermelons isincreased by 15.0% or more, the yield of the Chinese cabbages is increased by 5.0% or more, and comprehensive economic benefits are increased remarkably.

Description

technical field [0001] The invention relates to a method for synergistically and efficiently planting cotton melons and vegetables (cotton, watermelon, and cabbage) in saline-alkali land, and belongs to the technical field of crop planting. Background technique [0002] Cotton production in saline-alkali land has always been dominated by monocropping. This single planting method has led to low cotton planting benefits and a significant reduction in cotton planting area, which has become a bottleneck that seriously restricts the stable development of cotton production. At present, the benefit and area of ​​cotton planting still continue to decline, and the situation of cotton production is very severe. [0003] Cotton is a pioneer crop and an important economic crop in saline-alkali land. For a long time, the exploration of cotton and other crop combination planting methods in saline-alkali land has never stopped, mainly including jujube-cotton intercropping, grain-cotton in...
