一、湖北省长江以北地区留蓄再生稻以处暑前收割头禾较为可靠,霜降前可望全部黄熟,不影响种麦。 二、头谷留椿高度,早割者宜较低,以争取多发泥荪,增加产量;迟割者宜较高,争取较多秆孙,以求早熟。 三、割口宜在节上寸许,太近易伤休眠芽,太远则影响其萌发。 四、“稈青子黄”为头禾收割适期,过份枯黄收割将影响休眠芽的活力,不利其萌发;这对肥田留蓄再生稻尤当注意。 五、如能适时收割头禾,割后不必进行灌蔸;且田面保持湿润即可,不必长期保蓄浅水。
First, the area north of the Yangtze River in Hubei Province to retain regenerative rice to summer before harvest head Wo more reliable, expected to be all before the Huangshuang frost, does not affect the wheat. Second, the height of the head Valley tortoise, early cut those who should be lower in order to fight more muddy sun, increase production; late cut who should be higher, for more stalks, in order to premature. Third, the cut should be in the section inch Xu, too easy to hurt dormant buds too far affect their germination. Fourth, “stem green child yellow” for the first crop harvest Hei, excessive yellowish harvest will affect the vitality of dormant buds, unfavorable to its germination; Fifth, if timely harvest He Wo, after cutting do not have to carry irrigation; and the field can keep moist, do not have to save long-term shallow water.
