How to prevent deformed Chinese yam? Please provide guidance methods
During the cultivation of Chinese yam, due to the influence of adverse environmental conditions, cultivation measures, management methods and other factors, changes occur in the internal tissue structure of Chinese yam during its growth process, thereby producing various bizarre shapes, such as branching at the upper end of the tuber, branching at the lower end, snake shape, flat head shape, foot shape, gourd shape, pockmarked shape, etc. These are collectively called deformed Chinese yam. The preventive measures are as follows:
1. Remove foreign objects in the trench. When manually digging the Chinese yam trench, it should be done before winter. Through the erosion of winter and spring rain and snow and freezing weathering, the soil clods are fully weathered and crushed. Fill the trench as the soil thaws from weathering, and when filling the trench, carefully remove stones, bricks, gravel and other hard objects from the soil, and do not fill large clods of soil into the trench.
2. Plant according to technical regulations. Do not apply seed fertilizer in the planting trench. When applying poisonous soil or poisonous bait to control underground pests, do not blindly increase the dosage. You can spray the soil surface with 800-fold diluted Xin Gaozhi Mo (new high-fat film) to reduce the amount of pesticide, keep warm and prevent freezing, prevent soil compaction, and suffocate and isolate sources of pests and diseases.
3. Apply fully decomposed organic fertilizer, such as human excrement and urine, compost, barnyard manure and high-quality miscellaneous soil fertilizer. Take advantage of the favorable opportunity of high temperatures in summer and autumn, which make fermentation and decomposition easy, to compost in advance. When the leaves begin to expand, spray the foliage with Yaocai Gendaling. This causes the products of leaf photosynthesis (nutrients) to be transported to the root system, improves the nutrient conversion rate and soil loosening capacity, enables the rhizome to expand rapidly, and greatly increases the medicinal content.
