Cultivation method suitable for circular harvesting of Guizhou mountain feed canna edulis ker

Abstract

The invention discloses a cultivation method suitable for circular harvesting of Guizhou mountain feed canna edulis ker. The cultivation method comprises the following steps: step 1, land selection; step 2, treatment of seed taros; step 3, sowing of the canna edulis ker for feeding; step 4, planting management; step 5, stubble reserving and harvesting; step 6, management after harvesting; and step 7, processing of the canna edulis ker for feeding. The method for planting the canna edulis ker as the forage grass is innovatively provided by batch planting of the canna edulis ker and circular harvesting of stems and leaves as main aspects, and the planting method has the following advantages that firstly, the planted canna edulis ker is large in biomass and rich in nutrient substances; secondly, the production potential of the canna edulis ker for feeding is fully exerted, and effective feed supply in the whole winter and spring can be realized; and thirdly, the problem of shortage of feed and silage in winter and spring during concentrated harvesting is relieved, the method can be suitable for economic structure adjustment in mountainous areas in Guizhou, and the problem that the economic benefit of traditional canna edulis ker tuber harvesting is not remarkable is effectively solved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method suitable for circular harvesting of forage plantain taro in Guizhou and mountain areas. Background technique [0002] With the rapid development of animal husbandry in Guizhou Province and the active promotion of the strategic adjustment of the planting industry structure in Guizhou Province, the demand for forage grass is large and the supply contradiction is serious. Due to the limitation of Guizhou's geographical environment, the production of natural pasture grass is low and the quality is poor, which has not been able to meet the needs of livestock feed. Demand, coupled with lagging grassland construction, has a large feed gap all year round, especially in winter and spring. Therefore, the "spring shortage" of forage material is one of the bottleneck problems that have long restricted the development of ecological animal husbandry in most areas o...

Problems solved by technology

[0002] With the rapid development of animal husbandry in Guizhou Province and the active promotion of the strategic adjustment of the planting industry structure in Guizhou Province, the demand for forage grass is large and the supply contradiction is serious. Due to the limitation of Guizhou's geographical environment, the production of natural pasture grass is low and the quality is poor, which has not been able to meet the needs of livestock feed. Demand, coupled with lagging grassland construction, has a large feed gap all year round, especially in winter and spring. Therefore, the "spring shortage" of forage feed is one of the bottlenecks that has long restricted the development of ecological animal husbandry in most areas of Guizhou; Guizhou's traditional characteristic economic crops have been used as feed in remote mountainous areas because of their wide adaptability, low planting technology requirements, high planting yield, and considerable feeding value. Harvesting tubers mainly, the cultivation of stems and leaves is less, and the utilization rate is not high; most of the existing planting techniques of canna taro are related to the harvesting and cultivation methods of canna tubers, and there is a lack of mature and perfect feed circular harvesting cultivation methods of canna stems and leaves , is not conducive to the popularization and application of forage canna taro, so it is particularly important to develop a circular harvesting cultivation method suitable for forage canna taro in mountainous areas of Guizhou
