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, a saline-alkali cotton field is selected. The basic situation is: the area is 1.5 hectares, the land is relatively flat, the soil fertility is even, and it has good irrigation and drainage conditions. Cotton has been planted for the first three years. The soil fertility of the cotton field is medium to upper level, and the multi-point measurement results are average. The soil total salt content of the plough layer (0-20cm) is 0.29% ± 0.03%, the organic matter is 0.91%, and the alkaline hydrolyzable nitrogen is 31.7 mg·kg. -1 , Available phosphorus 18.9mg·kg -1 , Effective potassium 118mg·kg -1 .

[0039] Half of the cotton field (called A1) is planted according to this planting method. 25 to 30 days before sowing, the irrigation is 700m per hectare. 3 The fresh water is used to suppress salt and create moisture. When the soil moisture is suitable (75% to 80% of the maximum water holding capacity of the field soil),...

Embodiment 2

[0055] A piece of 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 level, the soil fertility is even, and the fertility level is high. Cotton has been planted for the first three years. The cotton field belongs to the top soil fertility level, and the multi-point measurement results are average. The soil total salt content of the plough layer (0-20cm) is 0.22% ± 0.05%, the organic matter is 1.07%, and the alkaline hydrolyzable nitrogen is 35.7 mg·kg. -1 , Available phosphorus 19.7mg·kg -1 , Effective potassium 122mg·kg -1 .

[0056] Half of the cotton field (called A2) was planted according to this 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 planted a...

Embodiment 3

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

[0061] Half of the cotton field (called A3) was planted according to this 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 field (referred to as B3) was planted according to the conventional meth...

Abstract

The invention discloses a synergistic and efficient planting method of cotton melon and vegetables in saline-alkali ground. The method is that the planting belt is covered with plastic film, cotton and watermelon are arranged in the same film belt, the cotton narrow row is covered with plastic film in two rows, and the wide row is not covered with plastic film, which is the bare ground; every five cotton seedlings are alternately spaced, and the cotton rows are alternately spaced One row of watermelons were planted in a staggered position on the inner side of the same film strip; fertilization was concentrated in a column type under the middle film in a narrow row, and the watermelons were pruned by the method of three vines facing outwards. After the watermelons were harvested, cabbage was interplanted in a wide row of cotton. The invention maximizes the ecological effects of increasing temperature, preserving moisture, maintaining moisture, and suppressing salt in the coordinated precision planting of cotton, melon and vegetables in saline-alkali soil, and realizes the complementary advantages of cotton, watermelon and cabbage in saline-alkali land, early growth, stable growth, high quality and high yield, and synergy. High efficiency, the yield of cotton seed cotton is increased by more than 10.0%, the yield of watermelon is increased by more than 15.0%, and the yield of cabbage is increased by more than 5.0%, and the comprehensive economic benefits are significantly increased.

Description

technical field [0001] The invention relates to a synergistic and efficient planting method of cotton melon and vegetables (cotton, watermelon, cabbage) in saline-alkali land, and belongs to the technical field of crop planting. Background technique [0002] The production of cotton in saline-alkali land has always been dominated by monoculture. This single planting method leads to low cotton planting benefits and a substantial reduction in cotton planting area, which has become a bottleneck that seriously restricts the stable development of cotton production. At present, the cotton planting efficiency and area are still in a downward trend, and the cotton production situation 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 the combination planting techniques of cotton and other crops in saline-alkali land has never stopped, mainly including jujube-cotton intercropping, grain-cotton ...
