冬萝卜播期早晚,不仅影响产量与品质,也影响它的耐藏性。石河子地区的群众,一般认为七月中旬播种较为适宜。我们于一九六四年以露八分品种验证了这个经验。 1.不同播期生殖生长的变化 萝卜生殖生长的变化,从形态上看,包括花芽分化和未熟抽苔两个方面。花芽分化对肉质根的形成、产品质量影响不大。未熟抽苔则对产量、品质都是不利的。所以,生殖生长的状况,是确定播期的重要指标。
Winter radish sowing sooner or later, not only affect the yield and quality, but also affect its storage resistance. Shihezi area masses, generally believed that sowing in mid-July is more appropriate. We validated this experience in 1964 in the form of a tentacle. 1. Different sowing reproductive growth changes Radish reproductive growth changes, from the morphological point of view, including flower bud differentiation and immature bolting two aspects. Flower bud differentiation on the formation of fleshy roots, product quality has little effect. Unpublished bolting on the yield, quality are unfavorable. Therefore, the status of reproductive growth is to determine an important indicator of sowing date.
