摘要
闽紫1号是系统选育而成。早发性好,为早花型偏迟品种。植株较高大,茎秆粗壮,结荚花序数和结荚数都较多,分枝力中等。鲜草和种子产量都比光泽种和乐平种高。品质较优。其丰产栽培应适期早播,适当密植;早施磷钾肥;开好排灌沟,合理排灌;防治病虫害;留种田应增施硼、钼肥,喷施多效唑和适期收种等。
A new Chinese milk vetch (Astragalus sinicus) cultivar Mingzi No. 1 , which was bred by using systematic selection, has fast-growing, early blooming and late maturing characteristics. In comparison with the check plant, its fresh straw weight and seed yield increased 20% and about 30% respectively. Also Mingzi No. 1 gave better seed quality. The new cultivar suits to double crop system of rice. The high-yielding practices involve the suitable sowing period, density and early application of P, K fertilizer, well-arranged draining and irrigating ditches, the control of pests and diseases. In the fields for harvesting seeds, increasing B and Mo fertilizers and spraying palcobutrazol (MET) as well as suitable harvesting time are suggested.
