摘要
[目的] 明确不同花生品种耐酸性低钙能力的差异,筛选适宜在酸性低钙旱地生长、荚果饱满的品种,为花生品种的有效利用提供参考.[方法] 酸性低钙旱地种植19个花生品种,测定各品种的单株结果数、单株饱果数、单株生产力、百果重、百仁重、出仁率等指标.[结果] 酸性低钙土壤作用下,桂花166的饱果率74.1%,单株生产力30.1 g,百果重140 g,百仁重58 g,出仁率64%,为参试品种中最高;不同品种的单株结果数、饱果率、单株生产力、百果重、百仁重、出仁率差异较大,酸性低钙土壤对花生的影响具有种间差异性.[结论] 19个花生品种耐酸性低钙能力存在显著差异,参试花生品种中有1个品种为高耐酸性低钙品种,11个品种为中耐酸性低钙品种,其余7个品种为酸性低钙敏感品种.
Abstract
[Objective] To define differences of acid and low calcium resistance ability of different peanut varieties,screen peanut varieties that were suitable to grow in the acid and low calcium dryland and with pod full,which provide reference for the utilization of peanut varieties.[Method] 19 peanut varieties were planted in the acid and low calcium dryland,the pod number of per plant,full-pod rate,productivity per plant,100-pod weight,100-seed weight,kernel rate index were determined.[Result]In the acid and low calcium dryland,the index of Guihua 166 including 74.1% of full-pod rate,30.1 g of productivity per plant,140 g of 100-pod weight,58 g of 100-seed weight,64% of kernel rate were the highest;There were significant difference of pod numbers of per plant,full-pod rate,plant productivity,100-pod weight,100-seed weight root length,kernel rate among varieties,effect of the acid and low calcium dryland on peanut had the interspecific differences.[Conclusion] The acid and low calcium resistance ability of 19 peanut varieties exists a significant difference.There were 1,11 and 7 peanut varieties belong to high resistance to acid and low calcium varieties,medium resistance to acid and low calcium varieties and low resistance to acid and low calcium varieties.
