水稻的人工杂交法就是利用各种水稻不同的生态类型,等于将这些类型的优良特性,在杂交中有意识的加以结合,来创造新的产量更高的品种,以期使它们最大限度地适应于现代农业生产的各种条件。水稻的有性杂交法,国内外一般也都采用下列三种方法来实验,现各分述介绍如下: (一)水稻有性杂交法上应用的工具 (1)普通温度计1根;(2)暖水瓶(内盛45℃温开水)1个;(3)干净软毛笔1枝;(4)小剪刀1把;(5)小镊子1把;(6)干净白纸1张;(7)玻璃纸袋(长15厘米×濶3厘米)若干个;(8)纸牌(长8厘米×濶4厘米)若干个。
The artificial hybridization method of rice is to utilize different ecological types of rice, which is equal to combining these excellent characteristics with the conscious in hybridization to create new varieties with higher yield, in order to make them adapt to modern Various conditions of agricultural production. Sex hybridization of rice, both at home and abroad are generally also used the following three methods to experiment, are described below are described below: (a) hybrid rice method of application of tools (1) a common thermometer; (2) A thermos bottle (filled with warm water at 45 ℃) 1; (3) a clean soft brush 1; (4) a pair of small scissors; (5) a small tweezers; (6) a clean white paper; Paper bags (length 15 cm × 濶 3 cm) number; (8) Solitaire (length 8 cm × 4 cm).
