Using the large-plow furrowing method for clear-cut regeneration of black locust
1. Preparatory work. Large-plow furrowing means using a tractor to pull a large plow to furrow in a clear-cut black locust (Robinia pseudoacacia) site. A tractor with relatively high horsepower must be used. An ordinary iron plow for plowing farmland is sufficient, but a single plow is required. First clear branches and large stones from the site. 2. Plot selection. Large-plow furrowing requires concentrated, contiguous plots, a slope of less than 25 degrees, and a soil layer of more than 30 cm. 3. Technical requirements. The black locust root system is relatively shallow, the main root is not obvious, and the lateral roots are well developed. The main lateral roots are mostly distributed in the surface layer at a soil depth of 20-30 cm.

How to scientifically control the first generation of the second-brood striped stem borer in single-season rice
Control recommendations 1. For early-sown and early-transplanted single-season rice fields, carry out a full control treatment once from June 20-25, targeting mainly stem borers and small brown planthoppers, and also controlling early-occurring leaf folders and rice thrips. Use 5% fipronil (Regent) suspension concentrate at 40-50 ml/mu, diluted in 30 kg of water for spraying. 2. For fields where rice stripe disease has occurred, on the basis of pulling out and removing diseased plants, promptly apply chemicals to control small brown planthoppers. Use 40% chlorpyrifos (Xinnongbao, Saiben) at 100 ml/mu, diluted in 30 kg of water for spraying, and repeat the treatment after an interval of 5-7 days.

An introduction to the characteristics of General Wild Stone Cliff Tea
Wild Stone Cliff Tea grows and reproduces naturally on high mountain stone cliffs at an altitude of over 800 m. Because its requirements for the growing environment are extremely strict, it still cannot be cultivated in low mountain areas. It absorbs the clouds and mist of the high mountains, bathes in the radiance of the sun and moon, and takes in the spiritual energy of heaven and earth, free from any pollution. It is picked only around Qingming and Guyu each year, and its yield is extremely limited, making it a rare type of tea. This product uses the fresh leaves of high mountain wild Stone Cliff Tea as its raw material and is finely made by applying modern processing technology combined with traditional craftsmanship. After brewing, the liquor is clear and green, the brewed leaves show a white frost, the aroma is unique, with a rich water chestnut fragrance
