[目的]研究秋闲田秣食豆的高产栽培技术。[方法]采用正交试验与软件PASW Statistics 18的LSD法,对秋闲田秣食豆播种行距、种植密度与氮、磷、钾等5个影响因子进行比较试验。[结果]密度、行距与钾肥对秋闲田秣食豆生物产量具有重要影响。明确了秋闲田秣食豆高产配套栽培技术的优化方案:留苗密度75万株/hm2,并以氮肥(N)300 kg/hm2、磷肥(P2O5)112.5 kg/hm2、钾肥K2O)375 kg/hm2做基肥,播种方式以50 cm的行距进行条播。该方案的鲜草产量、干草产量分别为6 661.672 723.64 kg/hm2,较产草量位居第二的优良组合的鲜重、干重分别增产24.17%、27.63%。[结论]为秋闲田栽培秣食豆的生产实践提了供理论依据和技术支撑。
[Objective] The research aimed to study the high-yielding cultivation techniques of harvest beans in autumn. [Method] Using LSD method of orthogonal test and software PASW Statistics 18, five influencing factors of sowing row spacing, planting densities, nitrogen, phosphorus and potassium in autumn fallow fields were comparatively tested. [Result] The density, row spacing and potassium fertilizer had an important effect on the bioavailability of beans in autumn. The optimal plan of high-yielding cultivation techniques of beans in autumn was established: the density of retained seedlings was 750,000 plants / hm2, and the nitrogenous fertilizer (N) 300 kg / hm2, P2O5 112.5 kg / hm2 and potassium fertilizer K2O 375 kg / hm2 to do basal, sowing way to 50 cm spacing for broadcast. The fresh grass yield and hay yield of the program were 6666.62723.64 kg / hm2, respectively, which were 24.17% and 27.63% of the fresh weight and dry weight of the fine combination with the second highest yield respectively. [Conclusion] This paper provided theoretical basis and technical support for the production practice of cultivating mung beans in autumn.
