Effects of Fertilization of Astragalus smicus and Chemical Fertilizer on Early Rice Cultivation Benefits
摘要
Abstract
Objective] The aim was to determine the appropriate application ratio between Astragalus smicus and chemical fertilizer in early rice production.[Method] With Zhuliangyou 4026 as the test variety, setting up 7 treatments, blank as control, effects of Astragalus smicus and chemical fertilizer on early rice yield and economic benefits were studied , the optimal ratio between Astragalus smicus and chemical fertilizer was selected.[Result] The growth traits of each treatment were better than those of the control group.The plant height and ear length was highest in treatment of 80% chemical fertilizer+20%Astragalus smicus, as 87.1 and 20.9 cm respectively;yield was highest in 60%chemical fertilizer+40%Astragalus smicus, up to 8 052.0 kg/hm2 , yield in 80%chemical fertilizer+20%Astragalus smicus took the second place, output value up to 7 953.0 kg/hm2, yield increasing rate were 31.67%and 30.05%;economic benefit was maximum in 60%chemical fertilizer+40%Astraga-lus smicus, up to 17 715.0 yuan/hm2, profit up to 16 239.0 yuan/hm2 increased by 2 785.5yuan/hm2 compared with CK;nutrient accumulation was maximum in 80% chemical fertilizer+20% Astragalus smicus, N, P2 O5 , K2 O were 183.0, 79.5, 241.5 kg/hm2 respectively.[ Conclu-sion] 60% chemical fertilizer and 40% Astragalus smicus had the best effect, which is conductive to improving early rice yield and income.关键词
