Walnut and konjak interplanting cultivation method

Abstract

The invention provides a walnut and konjak interplanting cultivation method; in a walnut growth period, a low shading level will cause land and lighting waste; konjak has the features of enjoying moisture, coolness, weak light and shading conditions, and is afraid of ponding and high temperature; the land capable of growing konjak gradually degreases every year, so the walnut and konjak interplanting cultivation method can be used to improve land utilization rate, thus reducing walnut fruit tree management and konjak plantation labor cost, and short term (1-8years) and long term (8-20years) economical benefits are considered; walnut tree leaves have anti biomass capable of providing sterilization efficacy, so soft rot pathogen harming the konjak growth in the soil can be eliminated, thus reducing konjak infection probability.

Description

technical field [0001] The invention relates to the field of agriculture and forestry, in particular to a cultivation method for walnut and konjac intercropping. Background technique [0002] Soaked walnuts bear fruit late, and the growth period is generally 5 to 8 years. Three-year-old walnut trees can harvest about 2.5 kg of dried walnut fruits, five-year-old fruit trees can harvest about 5-10 kg of dried walnut fruits, and eight-year-old fruit trees can harvest about 250 kg of dried walnut fruits. period has no economic benefit. During the growth period of 5 to 8 years, the shading degree of walnut fruit trees is between 5% and 75%. Due to the reasons for shading and the need for protection of the rhizosphere of walnut trees, it is not suitable for planting high-stem crops. waste, and soil loosening, weeding, and water and fertilizer management require more labor input, and about 8 labors are needed per year.

Problems solved by technology

[0002] Soaked walnuts bear fruit late, and the growth period is generally 5 to 8 years. Three-year-old walnut trees can harvest about 2.5 kg of dried walnut fruits, five-year-old fruit trees can harvest about 5-10 kg of dried walnut fruits, and eight-year-old fruit trees can harvest about 250 kg of dried walnut fruits. no economic benefit

During the growth period of 5 to 8 years, the shading degree of walnut fruit trees is between 5% and 75%. Due to the reasons for shading and the need for protection of the rhizosphere of walnut trees, it is not suitable for planting high-stem crops. waste, and soil loosening, weeding, and water and fertilizer management require more labor input, about 8 labors per year

At the same time, due to the serious occurrence of konjac continuous cropping diseases, it is not suitable for continuous cropping. Even if crop rotation is used, the interval required for crop rotation is relatively long, and the rotation period is 5 to 10 years. Therefore, the land suitable for planting konjac is limited, and the planting cycle is two years. That is to say, "big relocation" will cause instability in the planting base

In addition, in the commonly used cultivation methods of konjac, the seed taro is easily injured and rotted in the links of harvesting, sorting, transportation, storage, and sowing, and even the spread of germs in these processes leads to frequent outbreaks of soft rot. The loss is generally 30% to 50%, and it can reach 80% in severe cases, or even no harvest. At present, there is no effective control method

The lack of suitable konjac planting land and the loss caused by the outbreak of soft rot have seriously restricted the development of konjac industry
