谷子施肥技术研究

[目的]探讨谷子施肥技术,为谷子高产栽培提供理论依据。[方法]以吉谷1号为供试品种,通过大田随机区组试验,采用A(N70%底肥和30%追肥)和B(N 30%底肥和70%追肥)2种施肥方法和N与P、K(作底肥)不同的施肥量,研究施肥与谷子产量的关系。[结果]在2种施肥方式下,随着N肥施用量的增加,谷子产量有明显增加的趋势,施N 100与50 kg/hm2和150与50 kg/hm2产量差异极显著,施N 150 kg/hm2与100 kg/hm2的产量差异显著;施P肥量由35 kg/hm2增加到70 kg/hm2时,谷子单产提高7.26%,差异达到显著水平;施K肥量由30 kg/hm2增加到60 kg/hm2时,谷子单产提高8.07%,差异也达到显著水平。[结论]就A与B 2种施肥方式相比,B施肥方式产量明显高于A施肥方式。

Study on Fertilization Technology of Millet

[Objective] The study aimed to discuss the fertilization technology on millet and provide the theoretical base for high yield cultivation on millet.[Method] In the field randomized block experiment with Jigu 1 as tested variety,the relationship between fertilization and millet yield was studied by using 2 fertilization modes as A with N 70% base fertilizer and 30% topdressing fertilizer and B with N 30% base fertilizer and topdressing 70% fertilizer and by applying N,P and k fertilizer(P and K as basic fertilizer) with different amount.[Result] Under 2 fertilization modes,the millet yield was increased obviously along with the increment of N application rate.The difference of the yield was extremely significant between applying N 100 and 50 kg/hm2 and also between applying N 150 and 50 kg/hm2 and the difference of the yield was significant between applying N 150 and 100 kg/hm2.When P application rate was increased from 35 to 70 kg/hm2 the millet yield was increased by 7.26%,with their yield difference at significant level and when K application rate was increased from 30 to 60 kg/hm2 the millet yield was increased by 8.07%,with their yield difference also at significant level.[Conclusion] In the comparison on the effects of 2 fertilization modes of A and B,the yield of millet with B fertilization mode was better than that with A fertilization mode.
