[0005] (2) Soil nutrient imbalance: the root system of yam penetrates deep into the soil and has a strong ability to absorb relevant nutrients in the soil. Heavy cropping makes the root system of yam selectively absorb, resulting in an imbalance of nutrient supply and easily causing nutrient deficiency
At the same time, nutrient imbalance can also cause soil compaction and damage to physical structure
[0006] (3) Self-toxicity phenomenon: In addition, many crops will produce self-toxicity after repeated cropping, and this phenomenon may also be one of the reasons for the reduction in production of yam under repeated cropping
[0013] Due to the above reasons, yam growers have to carry out 6-10 years of crop rotation and stubble rotation. my country has a large population and little land, and land resources suitable for planting yam are in short supply. Crop rotation and stubble rotation have brought great difficulties to the specialized and intensive production of yam With the development of the market economy, this contradiction has become increasingly prominent

Abstract

The invention relates to a Chinese yam planting method for preventing reduction of continuous cropping yield, which includes the steps: first, soaking yam seedlings in thiophanate methyl solution to obtain pretreated yam seedlings; second, planting the pretreated yam seedlings obtained in the step 1 in a ready plot, scattering strong rooting agent, spraying hymexazol, and irrigating roots with matrine; and third, performing field management and harvesting Chinese yam. By seedling soaking and soil sterilization, disease occurrence is greatly reduced for Chinese yam, yield and quality of Chinese yam are increased, the shortcoming that Chinese yam planting needs rotation of crops is overcome, rapid development of the yam industry can be promoted, and evident economic benefit and bright application prospect are achieved.

Description

technical field [0001] The invention relates to a yam planting method for preventing heavy cropping and yield reduction, and belongs to the technical field of crop production. Background technique [0002] The main reasons for crop yield reduction of plants involve many factors such as soil physical structure, soil nutrients, diseases and insect pests, etc. Chinese yam is a sensitive crop for heavy cropping, and heavy cropping can lead to weak growth, low resistance, premature aging, no swelling of tubers, and decreased yield and quality of yam. In the second year of heavy cropping, the production reduction rate can reach 30% to 70%, and even severe cases may even eliminate production. [0003] So far, there is still a lack of systematic research on the reasons for the reduction in the yield of yam cropping. Preliminary analysis suggests that the main reasons for the reduction in yield of yam cropping are: [0004] (1) Diseases caused by repeated cropping: continuous croppi...
