棉花种植方式和密度效应研究 总被引:3,自引:0,他引:3
以JX013为材料,在湖南浏阳研究了不同种植密度(18000、36000、54000株/hm2)、不同种植方式(直播、漂浮育苗移栽、营养钵育苗移栽)对棉花生长发育及产量、品质的影响。结果表明:在同一种植方式中,生育期随密度的增加而延长,株高、果枝数、单株成铃数随密度增高而降低,单位面积总铃数、籽棉产量随密度增高而增加;在同一密度下,生育期以直播棉最短,株高、果枝数、单位面积总铃数、籽棉产量以直播棉最大;不同处理对棉花铃重、衣分、衣指、子指、纤维品质影响不显著。 相似文献

秸秆还田对水稻病虫害及产量影响研究 总被引:2,自引:0,他引:2
试验研究了秸秆还田对水稻病虫害发生的影响。结果表明,秸秆还田对水稻有一定的增产作用,但同时秸秆还田也会加重水稻病虫害的危害程度,生产上需综合考虑秸秆还田数量、年限、种植品种等因素,以达到增产同时不加重病害发生。 相似文献

以超级稻盐丰47为试材。采用小区对比试验方法,研究不同播量对滨海稻区水稻生育及产量的影响。结果表明,水稻秧苗的株高、叶面积指数与播量呈正相关,而叶龄、茎基宽、带蘖率、百株干重与播量呈负相关,并且随着叶龄的增加,各处理间的相对差异逐渐加大。抽穗期至成熟期干物质产量占籽粒产量的百分比、单位面积的颖花量及水稻产量随着播量的降低而增加。 相似文献

In pesticide application, it can be obtained by using appropriate nozzles and sprayers to reduce spray drift and pesticide residues. In this study, a field trail was conducted to determine the spray drift and pesticide residue of imidacloprid on wheat, using three types of flat fan nozzles from the LECHLER Company (LU120-02, AD120-02, IDK120-02) and two types of sprayers (guided-baffle shield sprayer (GBSS) and conventional sprayer (CS)). The spray drift (measured with both airborne and sediment samplers) and terminal residues on wheat were analyzed by liquid chromatography triple-quadrupole mass spectrometry. The results show that both the sediment drift and airborne spray profile were greatest for the LU120-02 nozzle, intermediate for the IDK120-02 nozzle, and lowest for the AD120-02 nozzle. The shielded sprayer gave one third of the drift recorded by airborne samplers and one half of the drift recorded by sediment samplers, compared with results from the CS. Airborne spray drift decreased with increasing height. The imidacloprid residues on wheat grain from different application methods were all below the maximum residue limit (MRL) suggested by EU (0.1 mg/kg) or China (0.05 mg/kg) and no imidacloprid residue was detected on wheat straw. Considering the factors on environment protection, food safety, and biological efficacy, the AD120-02 nozzle and GBSS performed better compared with other nozzles and sprayers. The combination of AD120-02 nozzle with a GBSS is likely to be the optimum application method on wheat. 相似文献
