Problems solved by technology

According to the needs of ensuring food security, it is estimated that in the next 5-10 years, my country's cassava planting area will expand to 1 million hectares, with a total annual output of 40 million tons. The current planting area is about 500,000 hectares, with a total output of about 8 million tons. The level is far from meeting the development needs of the domestic cassava industry
However, as an emerging industry, its development still faces many uncertainties. Among them, the most important uncertainty is the low efficiency of cassava planting. The average yield of cassava in my country is 16-20 tons / ha, and the output value per mu is less than 1,000 yuan. , low planting efficiency seriously restricts the development of cassava industry
[0004] Watermelon is an annual vine plant. It is transplanted and planted in the middle and late March, and the harvest can be completed from the end of June to the middle of July. The growth period is short, and the yield per mu can reach 3000-4000 kg. It leads to the occurrence of pests and diseases, seriously endangering the yield and quality. At the same time, the row spacing of watermelons is large, and the utilization efficiency of light and heat resources on the land in the early stage of growth is low. Therefore, suitable crops and watermelons are selected for reasonable interplanting and crop rotation. Heat resources, on the other hand, can alleviate the obstacles of watermelon continuous cropping, and ultimately improve the sustainable production capacity of watermelon planting land

Embodiment 1

[0030] In 2015, in Congguang Village, Chengxiang Town, Wuming District, Nanning City, Guangxi, watermelons, cassava and sweet potatoes were planted in intervals, sets and rotations according to the following methods. The watermelon variety is Black Beauty.

[0031] Including the following steps:

[0032] (1) Land consolidation and fertilization: plow and level the soil, dig a watermelon ditch about 40cm deep, and apply base fertilizer in the watermelon ditch according to the standard of 60 kg of compound fertilizer and 250 kg of organic fertilizer per mu, and fertilize the ditch with watermelon Start a watermelon border with a width of 60cm in the center, and the distance between the two watermelon borders is 3.5m. Open the first cassava fertilization ditch at the center between the two watermelon borders, and open another two at 60cm on both sides of this ditch. Fertilization ditch, a total of 3 cassava fertilization ditch. And apply basal fertilizer in the cassava ditch ac...

Embodiment 2

[0041] In 2016, in Qinwai Village, Luwo Town, Wuming County, Nanning City, Guangxi, watermelons, cassava and sweet potatoes were planted in intervals, sets and rotations according to the following methods. The watermelon variety is Qilin melon.

[0042] The planting method comprises the steps of:

[0043](1) Land consolidation and fertilization: plow the soil deeply and level off, dig a watermelon ditch with a depth of 45 cm, and apply base fertilizer in the watermelon ditch according to the standard of 60 kg of compound fertilizer and 300 kg of organic fertilizer per mu, and fertilize the ditch with watermelon Start a watermelon furrow with a width of 60cm in the center, and the distance between the two watermelon furrows is 3.8m. Open the first cassava fertilization ditch at the center between the two watermelon furrows, and open another two at 55cm on both sides with this ditch as the center. Fertilization ditch, a total of 3 cassava fertilization ditch. And apply basal f...

Abstract

The invention belongs to the technical field of agricultural planting, and discloses an intercropping and rotation planting method of watermelon, cassava and sweet potato, which comprises the steps: (1) carrying out land preparation, fertilization and furrowing; (2) planting watermelon and cassava in the middle and late March; (3) providing conventional field management; (4) harvesting the watermelon from late June to middle July; (5) after the watermelon is harvested in July, topdressing the cassava; (6) intercropping sweet potato in September to October; (7) harvesting the cassava from lateNovember to January next year: and (8) plowing and earthing the sweet potato 20-30 days earlier in January to February next year according to a planting plan of the year. According to the invention, reasonable layout is provided, the watermelon is intercropped in the early growth period of the cassava, and a green manure crop is timely inserted after the watermelon is harvested, the economic benefit per unit area is increased, the continuous cropping obstacle of the watermelon is avoided, the combination of land use and land maintenance is achieved, and the sustainable development of the cassava and the watermelon is coordinated. The method disclosed by the invention is simple to perform, and is particularly suitable for large-area popularization in multiple provinces of southern China.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for planting watermelon, cassava, and vetch between crops, sets and rotations. Background technique [0002] Cassava, sweet potato and potato are known as the world's three major potato crops. It is the most important carbon source food crop after rice, sugarcane and corn in tropical and subtropical regions. Its roots provide food for more than 600 million people in the world and are widely used in my country. Used in starch, feed, food, medicine, paper, alcohol, textile and other industries, it is an extremely important bioenergy crop. According to the needs of ensuring food security, it is estimated that in the next 5-10 years, my country's cassava planting area will expand to 1 million hectares, with a total annual output of 40 million tons. The current planting area is about 500,000 hectares, with a total output of about 8 million tons. The level is far ...
