【摘要】 越冬栽培的番茄通过再生整枝方式,产量可达10995kg/667m2 ,其越冬后再生番茄比对照处理增产46.6%,其增产因素主要是增加了穗数、花数、果数,而单果重与对照相近。再生整枝后植株对N、P、K、Mg、Fe、Cu元素的吸收增加,特别是植株体内的N、P、K含量分别超过对照59.1%,37.5%,61.8%。更多还原

【Abstract】 The tomato fruit yield of 10995 kg/667 m~2 was obtained by re-growth pruning of over-winter cultivated plants. Re-growth pruning of over-winter cultivated tomato plants increased fruit yield by 46.6% which was mainly due to increases in the numbers of spicas, flowers, and fruits. However, re-growth pruning of over-winter cultivated tomato plants did not increase fruit weight. Re-growth pruning increased the uptakes of N, P, K, Mg, Fe, and Cu. Re-growth pruning increased the contents of N, P, and K in the plants by 59.1%, 37.5%, and 61.8%, respectively.更多还原
