Opinions on the Occurrence of Sclerotinia Rot in Rapeseed and Its Control Techniques
This year's rapeseed growth is characterized by an earlier growth period than last year and a growth vigor close to last year's. The occurrence characteristics of rapeseed sclerotinia rot this year differ from previous years. Based on a comprehensive analysis of multiple factors including field inoculum sources, rapeseed growth vigor, varietal disease resistance and climatic conditions during the susceptible growth period, the natural occurrence level is a moderate-to-severe epidemic. ...

Detailed Explanation of Key Techniques for High-Yield Organic Chestnut Cultivation
Carrying out winter pruning of chestnut trees in the full-bearing period is an effective measure to extend the full-bearing period and prevent the occurrence of alternate bearing. 1. Pruning timing: The winter pruning period for chestnuts is best from half a month after leaf fall to half a month before spring bud break the following year, that is, from mid-December to early February of the next year, but when encountering ice...

Key Management Techniques for Water Spinach in Solar Greenhouses
After water spinach seedlings are transplanted or direct-seeded seedlings emerge, intertillage and soil loosening should be carried out several times to raise soil temperature, promote root development, and thoroughly remove field weeds. Water spinach requires relatively little water during the seedling stage, so irrigation can be done moderately. After harvesting begins, the soil should be kept moist. After the first harvest, apply 15 kg of urea or diammonium phosphate per mu...

Key Management Techniques for Persimmon Trees Before and After Flowering
Management of persimmon trees before and after flowering. Persimmon trees are light-loving crops, and in dense planting cultivation, attention should be paid to solving ventilation and light penetration, which is the main measure for high-yield management. Persimmon trees bear fruit from axillary buds, so thinning out vigorous growing branches and strengthening nutrient accumulation in branches and trunks are very important. Before flowering, emphasis should be placed on applying amino acids to the trunk to promote flower bud differentiation, overcome alternate...
