jointing stage

Identification of young ear's low temperature sensitive phase after jointing stage of winter wheat

冬小麦拔节后幼穗低温敏感期的鉴定

When the nitrogen applied at the base, the jointing stage and the large bell of 1:3:1 fertilizer, the corn anti-aging was strongest. 2.

当氮肥分别在基施、拔节期与大喇叭口期1：3：1施用时，玉米抗衰老能力最强。

Test observation was carried out between jointing stage and tasseling stage of maize.

试验于玉米长至拔节抽雄期时观测玉米冠层温度。

After jointing stage, the differences are significant narrowing, and have little to do with the content of pollen-shedding.

拔节期后，差异明显缩小，且与吐丝散粉期含量变化不大。

The wheat infected by WBD did not show the symptom during the winter time and with the coming of the jointing stage it will display the symptom when the wheat start to turn green during the spring time in April and May.

受WBD侵染的小麦一般冬前不表现症状，春季4、5月小麦返青后随着拔节期来临病害开始显症。

The surface soil temperature in bared belt was 2-5 ° C higher than that in inter rows after jointing stage.

拔节后预留行地表温度比麦行高2~5°C。

Effects of 2,4-D Butylate Sprayed at the Jointing Stage on Agronomic Characters of Three Wheat Varieties

拔节期喷施2,4-D丁酯对3个小麦品种农艺性状的影响

At jointing stage, the vertical and horizontal distribution of corn root cultivated in light loam was the most extensive, followed by loam and light clay.

拔节期，玉米根系的垂直和水平分布在轻壤土中范围最广，轻粘土中最小。

The SPS and SS content in the summer maize stems increased from jointing stage to great bell mouth stage, and reduced from great bell mouth stage to heading stage.

夏玉米茎秆中SPS、SS活性从拔节期到大喇叭口期增大，大喇叭口期到抽雄期再逐渐减小。
