Analysis of Cotton Production Misconceptions and Ways to Increase Yield Through Plant Protection (Part 5)
For more than a decade, with the widespread promotion of genetically modified insect-resistant cotton, cotton bollworm is no longer enough to make cotton farmers turn pale at the mention of pests. However, Fusarium wilt and Verticillium wilt have always been the "tightening band" giving cotton farmers headaches, aphids and red spider mites "stir up trouble" every year, cotton stink bugs and tobacco whiteflies have become increasingly rampant in recent years, and together with cotton bollworm suddenly breaking out in certain years, pesticide control of cotton is still an unavoidable matter.

Technical measures for snow and freeze protection of mulberry trees, tea trees and fruit trees
I. Fruit: (1) Citrus: Before freezing, spray an anti-transpirant insulation agent on the tree canopy, and light smoke in the orchard to improve the freeze protection effect. For citrus affected by freezing injury, promptly remove curled, frost-killed leaves and withered shoot tips, bandage branches damaged by snow pressure, prune and shape branches broken by pressure, treat wounds with a wound protectant, promptly spray foliar fertilizer, and strengthen fertilizer and water management. For lightly frozen trees, apply 0.5% urea as a foliar topdressing 2-3 times; for severely frozen trees, it is advisable to apply light fertilizer multiple times in split applications.

After spring tea is picked, the tea plant branches and stems need even more protection
Whether or not tea plants are managed after the spring tea harvest makes a big difference, because after the spring tea harvest the plant body has already consumed a large amount of nutrients. If management cannot keep up at this time, it will not only affect the yield and quality of summer and autumn tea, but also affect the yield and quality of next year's spring tea. Based on our farm's practical experience, the following key points should be carried out after the spring tea harvest: 1. Reasonable topdressing. According to measurements, producing every 50 kg of dry tea requires absorbing about 2.5-3 kg of nitrogen, 0.9-1.2 kg of phosphorus, and 1.1-1.5 kg of potassium from the soil. Between the tea plants, 30 cm

Key points of seedling protection techniques for newly planted early-sprouting tea: improving the survival rate of tea seedlings
In recent years, Chun'an County has accelerated the pace of developing clonal early-sprouting tea. By early 2007, Chun'an County had planted 53,000 mu of clonal early-sprouting tea (1 mu = 667 sq m, the same below), of which 38,000 mu were in production, and another 15,000 mu still needed strengthened drought resistance and seedling protection, with management aimed at improving the survival rate. Especially for tea gardens planted last winter and this spring, the following seedling protection measures must be effectively adopted. 1. Mulch with grass at the right time. Mulching with grass can preserve water and lower temperature, and loosen the soil; it is a key drought-resistance technique. Cutting grass
