Problems solved by technology

Since the growth cycle of sweet potato is longer than that of common crops, intercropping is difficult. As for planting sweet potato in the cassava / wax gourd intercropping system, planting and management are more difficult. So far, there has been no research report on the compound intercropping method of cassava, wax gourd and sweet potato. There is also no related intercropping technology, and related technical reference

specific Embodiment approach 1

[0056] A compound intercropping method of cassava, wax gourd and sweet potato. The area of ​​the experimental group is 6 mu, and the other 3 mu is the control group using cassava net cropping mode. It is located in the red soil development zone, Weishangqiao Town, Dongxiang County, Fuzhou City, Jiangxi Province , the geographical coordinates are N28°13′42″ north latitude, E116°32′40″ east longitude.

[0057] This specific embodiment one intercrops 2 rows of wax gourds on 2 fertilization ditch between the wide row spacing of cassava, and then intercrops 2 rows of sweet potatoes to form a composite intercropping unit. As shown in the accompanying drawing, the composite intercropping method includes variety selection, planting time, Planting mode, planting density, planting density ratio, planting row ratio, field management, and harvesting, including land preparation and ridging, intertillage weeding in the early growth period, intertillage weeding in the middle growth period, an...

specific Embodiment approach 2

[0080] Basically the same as the specific implementation mode 1, the difference is:

[0081] 1) The cassava variety is Guire 4.

[0082] 2) Plant 2 rows of cassava on a single ridge to build a wide and narrow row pattern with a wide row spacing of 2.3 meters, a narrow row spacing of 0.8 meters, and a plant spacing of 0.8 meters; plant 2 rows of wax gourd on a single ridge to build a wide and narrow row pattern with a wide row spacing of 2.1 meters and a narrow row spacing of 1.0 The plant spacing is 2.0 meters; the sweet potato is planted in a straight line with the wax gourd plants, and two rows of sweet potatoes are planted on a single ridge to build a wide and narrow row pattern. The wide row spacing is 2.1 meters, the narrow row spacing is 1.0 meters, and the plant spacing is 0.5 meters.

[0083]3) The planting density of cassava was 8064 ha / ha; the planting density of winter melon was 3226 ha / ha; the planting density of sweet potato was 9678 ha / ha.

[0084] 4) Thin out c...

specific Embodiment approach 3

[0088] Basically the same as the second embodiment, the difference is:

[0089] 1) The cassava variety is Xinxuan 048, and the sweet potato variety is Ganshu 1.

[0090] 2) Plant 2 rows of cassava on a single ridge to build a wide and narrow row pattern with a wide row spacing of 2.7 meters, a narrow row spacing of 0.8 meters, and a plant spacing of 0.8 meters; plant 2 rows of wax gourd on a single ridge to build a wide and narrow row pattern with a wide row spacing of 2.5 meters and a narrow row spacing of 1.0 The plant spacing is 2.0 meters; the sweet potato is planted in a straight line with the wax gourd plants, and two rows of sweet potatoes are planted on a single ridge to build a wide and narrow row pattern. The wide row spacing is 2.1 meters, the narrow row spacing is 1.0 meters, and the plant spacing is 0.5 meters.

[0091] 3) The planting density of cassava was 7142 ha / ha; the planting density of winter melon was 2857 ha / ha; the planting density of sweet potato was 8...

Abstract

The invention provides a compound interplanting method for cassava, white gourd and sweet potato. The method comprises following steps: intercropping two rows of white gourd on two dressing furrows between wide rows of cassava, and then intercropping two rows of sweet potato; varieties are chosen from Jiangxi potato No.1, Jiangxi potato No.2, Ganning Zi No.1 and Xu potato 22; the white gourd is planted in last third of the March to the beginning of the April, around Tomb Sweeping Day; the sweet potato is planted in the middle and last ten-day of the May; the plantation density ratio of cassava, white gourd and sweet potato is (2.5 to 3.3):1:(3 to 4); the ratio of the number of plantation rows is 2:2:2; fertilizer is not applied after the harvest of white gourd; the harvest times of sweet potato and cassava are the same. By means of the method, the problems of large space between rows of cassava after the white gourd is harvested, the waste of light and temperature resource, and the invasion of weeds are solved; the cropping index, the land coverage rate and the land integrated loading and unloading capacity are greatly increased; water and soil loss is reduced; high-yield and high efficiency plantation technology mode for cassava is provided. Field trial shows that increased income of more than 51.3 thousand Yuan is obtained by the test group compared with the cassava single-planting control group, the amplification is more than 557.61%.

Description

technical field [0001] The invention relates to dryland intercropping, in particular to a compound intercropping method of cassava, wax gourd and sweet potato. Background technique [0002] Cassava (Manihot esculenta crantz) belongs to the cassava plant of the Euphorbiaceae family. It originated in the Amazon River Basin in tropical America. Planting cassava has the advantage of not occupying fertile land, which can alleviate the national energy and food crisis. The cassava plants are tall, the planting density is low, the row spacing of planting plants is wide, the growth rate in the early stage is slow, and the closing time of seedlings is late. The economic benefit of cassava net seeding is low, and it cannot make full use of light, temperature, water and heat resources, which is easy to cause water and soil erosion, and the comprehensive soil productivity is low. If the planting density of cassava is appropriately reduced, the row spacing of cassava planting is expande...
