摘要
Objective] The alm was to study the high-yield cuItivation technique of fodder soybean（Glycine max （L.） Merr.） in autumn idIe Iand. [Methods] Such five in-fIuencing factors as Iine spacing, pIanting density, nitrogen （N）, phosphorus （P） and potassium （K） of fodder soybean seeding in autumn idIe Iand were compared using orthogonal experiment method and LSD method of PASW 18 statistics software. [Results] The resuIts showed that density, Iine spacing and K2O had important ef-fects on bioIogical yield of fodder soybean in autumn idIe Iand. Moreover, the opti-mum proposal for high-yield matching cuItivation technique of fodder soybean in au-tumn idIe Iand was determined as foI ows： pIanting density was 75 ＆#215;104 pIants/hm2;300 kg/hm2 N, 112.5 kg/hm2 P2O5 and 375 kg/hm2 K2O were viewed as basic fertiIiz-ers; the seedIing styIe was sowing in driI with the Iine spacing of 50 cm. In the proposal, fresh and hay grass yields were 6 661.67 and 2 723.64 kg/hm2, respec-tiveIy, which increased by 24.17% and 27.63% respectiveIy compared to the second fine combination. [Conclusions] The resuIts provided a theoretical basis and technical support for the production of fodder soybean in autumn idIe Iand.
[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。
