Abstract: | In this paper , the influences of chilling injury on wheat spike characters after jointing stage were studied under fertilization and irrigation regulation .The results showed that irrigation two times ( winter water and jointing water ) and one time ( only winter water ) increased the average grain number per spike by 25 .81%and 19 .89%respectively compared with no irrigation .The average grain number per spike could al-so increased by 6 .53%through application of organic fertilizer compared with no organic fertilizer . |
