Variety Screening And Cultivation Techniques Of Peanut In Xinyi City

Peanut is one of the main crops in Xinyi City in recent years, and the economic benefits of planting peanuts is higher than that of other crops. So peanuts become important economic crops in structural adjustment of Xinyi city. With the growth of population and the continuous improvement of people’s living standard, the crop of production and quality requirement are also getting higher and higher. Thus, peanut Yield and quality have higher requirement. The goal of this thesis is to study new peanut varieties and cultivation techniques, and further promote Xinyi peanut increase production and variety optimization. We screen the main cultivated peanut varieties and several new varieties, totally12varieties, by field experiment, analysis of peanut yield, and characters of high yield varieties. Finally, Yuanza0025were selected to carry out experimental observation. The main results are as follows:1. Selection planting peanut varieties.1) Yield:the highest is Yuanza0025, this vultivar has more fruit number, bigger fruit, and yield has599kg/mu, this is significantly higher than other tested varieties; followed by Xu9614, Wei41-10, Xuhua13;2) the rate of out-jen:the highest is Huayu23,71.38%;3) resistance:Yuanza0025, Xu9614, Wei41-10and Xuhua13have better resitance than others.2. Research of peanut cultivation technology. The results show that:1) Density:15×40cm is best than the other treatments, followed by15×50cm and15×30cm;2) Sowing date:the appropriate date is19-22th, April;3) Fertilizer:Fertilizer impact on yield of peanut yield from high to low is biological organic fertilizer, slow-release fertilizer, peanut special fertilizer, compound fertilizer and urea;4) Fertilizer Formula:the best economic benefits of the fertilizering compost is2500kg/mu, and apply the high fertility fields in Xinyi. Based on the fertilizering compost of2500kg/mu, urea, calcium and potassium chloride are necessary for high yield;5) Soaking seed:multi-effect spirit of peanut seed, peanut seedlings have resistance to many diseases (root and stem rot and so on) by treatment of "duoxiaoling", and this could produce higher yield and better quality.
