Cotton pre-sowing preparation
First, soil preparation and fertilization: on the basis of ploughing and freezing in winter, base fertilizer is applied in spring, with 3 cubic meters of commonly effective organic manure and 30 kg of available ternary compound fertilizer per mu, and then ploughed, raked and leveled. After rain, it is necessary to rake again to absorb and preserve soil moisture, and enough moisture to be planted. Second, seed preparation: (1) Variety selection. Disease-resistant and insect-resistant hybrid cotton varieties are selected, such as Yuza 35, Zhongmian 47, Zhongmian 48 and so on. (2) seed selection. Select the seeds with high purity, full grains, maturity and high germination rate. (3) seed drying.

High-yielding cultivation techniques of double cropping no-tillage and direct seeding of oil and rice
Zhejiang Province has a more developed economy and high labor value. at the same time, with the rise of diesel prices, the ploughing fee of cultivated land machinery increases, and the cost of grain and oil production increases year by year. For this reason, the experiment, demonstration and popularization of no-tillage and direct seeding high-yield cultivation techniques of oil and rice double cropping in Zhejiang Province have reduced the cost of grain and oil production and improved the planting benefit. According to the investigation, no-tillage direct seeding rape per mu is 62.5 yuan more cost-effective than transplanting rape, and no-tillage direct seeding late rice per mu is 70.24 yuan more cost-effective than ploughing and transplanting late rice.
