Method for realizing ecological cycle by combining planting and breeding in sugarcane field

Abstract

The invention discloses a method for realizing ecological cycle by combining planting and breeding in a sugarcane field. The method comprises the following steps: interplanting corns in the sugarcanefield at the early growth stage of sugarcane, processing fresh silage corns and sugarcane tail tips into a pig feed, and preparing biochar from withered straws; building a hog house and a chicken house beside the sugarcane field for raising pigs and chickens, wherein a cleaning waste liquid and pig urine of the hog house and the chicken house are used for drip irrigation of the sugarcane field, and excrement of the pigs and the chickens is used for raising hermetia illucens; feeding the chickens with produced hermetia illucens, after the chickens are hatched, breeding the chickens in the chicken house in a captive mode to a sugarcane elongation stage, and stocking the chickens to the sugarcane field; and preparing the hermetia illucens treated excrement and the biochar into a bio-organic fertilizer, and applying the bio-organic fertilizer to the sugarcane field so as to provide nutritional ingredients for growth of the sugarcane and the silage corns. By using of the method provided bythe invention, the sugarcane and the corns are planted; the pigs, chickens and hermetia illucens are bred; low input and high output of the sugarcane field can be achieved; and the ecological conceptof cyclic utilization is met.

Description

technical field [0001] The invention belongs to the technical field of combining modern agricultural planting and breeding, and in particular relates to a method for realizing ecological cycle by combining sugarcane planting and breeding. Background technique [0002] Cane sugar industry is one of the important advantageous industries in Guangxi, which plays a decisive role in the balance of supply and demand of sugar in our country. However, due to the high concentration of sugarcane planting, the output of sugarcane fields is far less than the market demand for sugarcane, and the soil fertility of some lands has been continuously cropped all year round, and the pests and diseases are serious. Single variety of sugarcane, degraded species and low yield per unit area are still the bottleneck problems affecting the development of sugarcane industry. At present, in sugarcane production, cultivated land is only used for sugarcane planting, and the three-dimensional planting an...

Problems solved by technology

[0004] Although the above two patents disclose an ecological model of combining sugarcane cultivation and breeding, the sugarcane-chicken breeding model is relatively simple, and it still requires more material and cost to maintain the operation of this model, and it will also produce relatively large amounts of food. For example, when sugarcane is harvested, a large amount of sugarcane tails will be produced. If the tails are not treated, a large amount of sugarcane tails will have a negative impact on the environment of the sugarcane field. If they are simply burned into carbon or crushed and buried Into the soil, the economic benefit is extremely low

Therefore, the ecological model disclosed in the above two patents is more suitable for small-scale sugarcane fields, and the benefits for large-scale sugarcane fields are not high; moreover, the continuous cropping of sugarcane in this model is likely to cause soil fertility to decline and serious pests and diseases
