The results show that from 2001 to 2016, average temperature tended to increase in the growth period of spring peanut in Dengzhou City, but the increasing trend was slow; precipitation showed a decreasing trend on the whole （it increased at the sowing and flowering stage）; sunshine duration reduced year by year （the decreasing trend was different at various growth stages）, but the decrease of sunshine duration was more obvious than that of precipitation. Based on the analysis of meteorological conditions and the growth rules of spring peanut, it is needed to scientifically choose varieties of spring peanut, plan suitable sowing patterns, apply and manage- fertilizer and water to reasonably realize sustainable high-yield of spring peanut based on its safe stable yield.展开更多

A member of the legume crops,it is rich in various nutrients and is one of the main oil crops for processing high-quality edible oil. Compared with other cash crops,planting peanuts can bring greater economic benefits to farmers. In this paper,we summarized techniques of cultivating spring peanut in open fields for years,and explored the problems and difficulties in the cultivation management process,in order to provide technical guidance for the farmers to carry out high-yield spring peanut production.展开更多
