为了筛选适合“中稻+再生稻”生产的水稻品种，在头季中稻生长前期按一季中稻生产方法进行田间管理，齐穗后15天左右施一次促芽肥。当谷粒黄熟度达到90%以上、且有70%的稻株倒二、三节芽伸长到2～3cm时，抢时收割头季，采取人工收割，留桩高度30cm，脱粒机不下田，尽量保护稻桩，收割后3～5天施肥一次。测得WZ-8再生稻产量为407.8 kg/667m2，“中稻+再生稻”产量为1186.9 kg/667m2，均为参试组合最高；其次是WZ-4，中稻产量和再生稻产量分别在600 kg/667m2和300 kg/667m2以上，总产为986.0 kg/667m2。结果表明：WZ-8的中稻、再生稻和“中稻+再生稻”产量均为最高，具有较大的“中稻+再生稻”生产潜力；其次是wz-4，也可作为本区域的“中稻+再生稻”品种。

This study was to select rice varieties adaptive to the semilate rice+ratoon rice production.The first rice crop at early grow ing stage was field-m anaged as same as semilate crop rice,fertilized once for sprout grow th about 15d after heading,m anual-harvested in time with 30 cm-high stubble left and threshers out of fields for rice stubble protection at over 90% of yellow mature grains and 70% of the rice plants’second and third node sprouts which elongated to 2 to 3 cm ,and fertilized once again 3 to 5d after harvesting.The results indicate thatthe ratoon rice yield of a variety WZ-8 is 407.8 kg/667m 2,and its sem ilate rice + ratoon rice yield is 1186.9 kg/667m 2,both of w hich are the highesteach in the test;and follow ed by WZ-4,its sem ilate rice yield and ratoon rice yield are more than 600 kg/667m2 and 300 kg/667m2, respectively,and its totalyield reaches 986.0 kg/667m 2.The sem ilate rice,ratoon rice or sem ilate rice + ratoon rice yield of the WZ-8 is the highest,with a higher potentialof sem ilate rice + ratoon rice production;and WZ-4 can also be used asasem ilate rice + ratoon rice variety in W anzhou region.
