Cultivation method for interplanting peanuts and sweet potatoes among wide rows of sugarcanes

Abstract

The invention discloses a cultivation method for interplanting peanuts and sweet potatoes in wide rows of sugarcanes. The cultivation method comprises the following steps: (1) land selection and preparation; (2) planting newly planted sugarcanes, performing field management and harvesting; (3) peanut planting, field management and harvesting; (4) sweet potato planting, field management and harvesting. (5) continuously interplanting peanuts and sweet potatoes in the ratoon sugarcane field; according to the method, the row spacing of sugarcane planting is increased, ventilation and light transmission among sugarcane rows are improved, the stem diameter and the single stem weight of the sugarcane are increased, and mechanization of the sugarcane and interplanting crops is better achieved; meanwhile, about half mu of land can be used for intercropping peanuts and intercropping sweet potatoes in each mu of sugarcane land, one more season of peanuts and one more season of sweet potatoes can be harvested under the condition that the per unit yield of sugarcane is 5-7 tons, 150-250 kg of fresh peanuts can be produced in each mu of sugarcane land, and the output value is 750-1500 yuan; by means of the method, 250-500 kg of fresh sweet potatoes can be produced, the output value is 500-1500 yuan, the planting income of a sugarcane field is effectively increased, and the land utilization rate and the multiple cropping index are further increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method for interplanting peanuts and sweet potatoes between wide rows of sugarcane. Background technique [0002] Sugarcane is the main sugar crop in my country, with a planting area of ​​about 1,381,900 hm in 2019 2 . In recent years, with the downturn in international sugar prices and the continuous rise in sugarcane planting costs, the planting benefits of sugarcane farmers have been greatly affected. The growth of sugarcane is relatively slow in the early stage, and it enters the rapid growth period from late June to early July and gradually closes. During this period, the rows of sugarcane plants become bare land, which not only wastes light energy, but also breeds weeds, increases farming hours, and is not conducive to soil moisture conservation. On the other hand, the continuous cropping time of sugarcane fields in my country is generally lon...

Problems solved by technology

During this period, the rows of cane plants become bare land, which not only wastes light energy, but also breeds weeds, increases the labor time of farming, and is not conducive to soil moisture conservation.

On the other hand, the continuous cropping time of sugarcane fields in my country is generally long, and the soil degradation is serious, which has become an important problem that plagues the sustainable development of sugarcane production in my country

There are other crops that occupy the sugarcane planting area, which is not conducive to the stability of the sugarcane planting area, and the interplanting of sugarcane is one of the measures to better solve the above problems
