After a decade of drought, the county of Gansu Province in Gansu Province has, after exploring and researching in recent years, creatively walked out of a dry farming road. There are three main methods: The first choice is to promote adaptive planting and industrial structure. The county has adopted a layout suitable for natural resource allocation and regionalization of crops, selected crops with strong drought resistance, high economic returns, and regionally significant crops, conducted comprehensive measures for specialized planting, and achieved higher economic benefits. In 2001, the county planted 160.88 million hectares of Chinese herbal medicines and planted 58 varieties, mainly including red (yellow) alfalfa and Codonopsis pilosula, which showed great advantages in drought resistance. Among them, 70% of per capita income in Shouyang Town comes from the Chinese herbal medicine industry. In order to make full use of the precipitation in July-September, Minxi vigorously promoted the cultivation of artichokes. In 2001, the county's artichokes reached 31,300 hectares, and the varieties developed towards diversification, forming two characteristic bases of high-starch type and processing type. This has gradually increased the commodity rate of artichokes, which has become the mainstay of farmers' income increase, and has greatly improved. In western Yunnan, agricultural production has the ability to resist nature. Secondly, it is necessary to strengthen adaptive dry farming that can improve the benefits of precipitation utilization without irrigation. The county uses membrane side furrow sowing, from 1998 to 2000, a total of 12,700 hectares were completed, of which the average yield of grain crops was 2104.5 kg, 35.4% higher than the open field. The mulch film coverage rate is 50%, and the soil conservation effect is achieved by inhibiting soil moisture evaporation and current collection. According to the determination, the dryland mulch-side wheat can increase the natural precipitation utilization rate from 20% to 60%, and the winter and spring in Fuxi County have frequent and ineffective rainfall, which can effectively relieve the winter and winter rapeseed overwintering drought. A dual-purpose membrane is a technique for increasing the revenue and reducing expenditure and pollution of wheat and winter rape seeded directly on the old membrane by using a hole seeder after the corn film is harvested. In 2001, the county promoted 133.33 hectares in the three townships of Santai, Yongji and Heping. The test results showed that the output per hectare was 2460 kg, and the yield was increased by 15% in the open, and various working hours such as mulching and farming, film coating, and digging of corn roots could be saved. 100 kilograms has a considerable effect on the fertility of the soil and the ability to increase soil moisture and water storage capacity. Under the existing conditions, full use of Sanshui (sky water, ground water, and groundwater) has been developed rapidly in Qianxi County in the past two years. The county has built 45710 eye water cellars, which can be nearly 1. 20,000 hectares of food crops and cash crops are subject to limited supplementary irrigation. About 50 cubic meters of rainwater is stored in a water storage pit, which can supplement 0.13 hectares of crops with natural rainfall. Application in Daejeon shows that growing corn can increase production by 18%-20%. In addition, the application of high-tech products - soil water retention agent. It can quickly absorb the excess water in the soil and release it slowly to meet the needs of the plant growth process and become a “small reservoir†when crops are arid. In 2001, the county mainly promoted the application of anti-drought and water-retaining agents in the cultivation of artichokes, spreading an area of ​​0.28 million hectares. The results showed that the emergence period could be 6-7 days ahead of time, and the emergence rate was increased by 10.2% compared with the control, which enabled the aphid to safely pass through the water shortage season in western Yunnan and increase the yield by 10%.
