种衣剂对花生产量及生长发育的影响

Effects of Seed Coating on the Yield,Growth and Development of Peanuts

为了探索种衣剂在花生上的应用效果,以闽花6号为供试材料,分别在龙海市港尾镇、隆教乡及白水镇3个试验点进行种衣剂对花生产量和生长发育影响的试验研究。结果表明:与不使用种衣剂(CK)对比,使用种衣剂处理的花生,出苗时间推迟2 d,出苗率提高6.38~7.63个百分点,百果重、千仁重、总分枝数、结果枝数、单株结果数和单株饱果数分别增加3.55%~8.42%、2.01%~4.42%、0.69~1.40条、1.4~2.73个和1.39~1.99个;饱果率和出仁率提高3.05~5.04个百分点和1.74~2.02个百分点;花生抗旱及抗病能力有所增强,叶斑病发病程度较轻;每667 m 2花生荚果产量和籽仁产量分别增加23.46%~28.49%、23.27%~27.82%,差异均达显著水平。

In order to explore the application effect of seed coating on peanut,by using Minhua No.6 as the test material,the effects of seed coating on the yield,growth and development of peanuts were studied in 3 test sites,namely Gangwei Town,Longjiao Township and Baishui Town of Longhai City.The results showed that:Compared with those treated without seed coating(CK),the emergence time of peanuts treated with seed coating was delayed by 2 days,and the emergence rate increased by 6.38-7.63 percentage points.The 100-pod weight,1000-kernel weight,number of total branches,fruiting branch number,fruiting number per plant and full pod number per plant respectively increased by 3.55%-8.42%,2.01%-4.42%,0.69-1.40,1.4-2.73 and 1.39-1.99.The rate of full pod and the yield of kernel respectively increased by 3.05-5.04 percentage points and 1.74-2.02 percentage points.The abilities of drought resistance and disease resistance of peanuts were enhanced,and the degree of leaf spot disease was not heavy.The pod yield and seed kernel yield of peanuts per 667 m 2 respectively increased by 23.46%-28.49%and 23.27%-27.82%,with significant differences.
