查询词典 maize

The roots of spring-sown maize and summer-sown maize could touch with each other in relay-planting system, which made the roots competed for water and nutrition. Thus, more of the water and nitrogen in those soil layers were used, which led to the decrease of water and nitrogen in those soil layers.

玉米根系数量和TTC还原总量在剖面分布上均发生交叉，春、夏玉米间存在养分与水分的竞争，使根系所达到的区域土壤养分和水分利用量增加，从而使相应土层土壤全氮含量和水分含量下降。

In detail, the lost percentages of N2 applied at the stage of spring maize sowing and two nitrogen level applied at pre-tasselling stage of spring-sown maize exceeded 40%, among them the lost percentage of N1 applied at pre-tasselling stage was highest.

同时，春玉米播种时底施N2和春玉米大口期追施的N1、N2氮的损失率均大于40％，其中春玉米大口期追施的N1时的损失率最高。

The results showed that, no matter mono-cropping and relay-planting, the grain SS activity of spring-sown maize and normal summer-sown maize were decreased at the early stage after anthesis, but after 40 DAA the decrease speed were slow and could maintain a high activity for a long time, which were benefit to the sucrose formation, accumulation and transportation.

结果表明，不管单作还是套作条件下增施氮肥前期春玉米和普通夏玉米籽粒SS活性略有降低，但花后40天后其活性降低慢，能长时间维持较高的值，利于蔗糖的合成、积累和转移。

Relay-planted with the same spring-sown maize, the quantity of nitrogen absorption of late maturity summer-sown maize was highest, but their nitrogen use efficiency was lowest, which because most the nitrogen absorbed were left in organs except grain.

与同一春玉米品种套作时，夏玉米为晚熟品种的吸氮量均较高，但其氮利用效率却较低，所吸收的氮更多的滞留在籽粒以外的植株器官中，向籽粒中转移的较少。

3 Effects on paste properties and starch contents It showed that relayed with different maturity summer-sown maize, the paste properties and starch content and its compositions of the spring-sown maize could not be affected obviously.

2.3 春、夏玉米淀粉含量、组成及糊化特性差异套作对春玉米淀粉含量、组成及糊化特性影响较小，但却显著影响与之套作的夏玉米的淀粉含量、组成及糊化特性。

2 Effect on yield and quality The results indicate that relay-cropping with summer-sown different maturity maize cultivars, there are no obvious effects on biomass, grain yield, and nutritive values (crude protein yield, crude fiber yield, crude fat yield) of the same spring-sown maize cultivars.

2.2 产量及营养价值差异研究结果表明，套作对春玉米生物产量和营养价值影响不显著；但能显著影响夏玉米的生物产量和营养价值。

But relay-cropping with spring-sown different maturity maize cultivars can obviously affect the biomass, grain yield, and nutritive values of the same summer-sown maize cultivars.

当夏玉米为同一品种时，夏玉米生物产量和营养价值表现为：与春玉米LD14套作＞与春玉米YD22套作＞与春玉米YD13套作。

4 Rhizosphere effects on starch paste properties There were no obviously rhizosphere effects on the paste time and temperature of spring-sown maize and summer-sown maize.

相同氮水平下，低氮时根际作用对春玉米Peak、Trough、Breakdown、Visco、Setback均为负效应；高氮时除Breakdown外均为正效应。

But the rhizosphere effects on spring-sown maize and summer-sown maize were quit different. At level of N1 and N2, rhizosphere effects had decreased the dry matter, grain yield, crud protein yield and crud fibre yield, while increased the grain starch content and the ratio of amylopectin to amylase.

两个氮水平下，根际作用对春玉米生物产量、籽粒产量、粗蛋白产量、粗纤维产量表现负效应，而对籽粒淀粉含量、直链淀粉含量、支链淀粉含量及支/直则为正效应。
