不同花生品种耐酸性低钙能力比较

Comparision on Acid and Low Calcium Resistance Ability of Different Peanut Varieties

[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。

[ 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-seod weight, kernel rate index were determined. [ Restdt] 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-seod weight root length, kernel rate among varieties, effect of the acid and low calcium dryland on peanut had the interspecific differ- ences. [ ConclusionJ 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 iow calcium varieties, medium resistance to acid and low calcium varieties and low resistance to acid and low calcium varieties.
