行距对小麦产量和品质的影响

Effects of Row space on Grain Yield and Quality of Wheat

在高肥条件下就6种行距对小麦籽粒产量和蛋白质、赖氨酸含量,以及对单位面积蛋白质产量的研究表明,试验条件下的行距23.3厘米和26.7厘米的籽粒产量和蛋白质产量最高,行距过大过小均使之下降。籽粒产量和营养品质的变化呈现出相反的趋势。行距对产量的影响大于对籽粒营养品质的影响。在生产实践中选择行距时应主要考虑产量高低。在某种行距下籽粒产量越高,蛋白质产量也越高。

The effects of 6 row space on grain yield and contents and lysine and protein yield of wheat the high-yield condition have been researched. Under the experemeut condition it has been obtained that 23.3cm row space got highest grain yield and 26.7cm row space got highest protein yield, that over-wide or over-narrow r-w space all make them lower, that the effects of row space on the grain yield is larger that on the nutritive quality, that yield should be first considered in practice when row space is arranged, that under centain row space, the higher grain yield, the higher protein yield.
