早稻测土配方施肥3414肥效试验初报 总被引:17,自引:3,他引:17
在柳江县成团镇白露村开展水稻田间"3414"肥效试验,研究县域不同土壤类型早稻最佳施肥量。结果表明:在土壤有效养分含量丰缺程度为中N、低P、低K的田块上开展肥效试验,14个处理中以每公顷施N 180kg、P 60 kg、K 202.5 kg处理(N2P2K2)的水稻产量最高,为6628.5kg/hm2;用二次回归分析,得出每公顷最佳施肥量为氮肥施140 kg,磷肥45 kg,钾肥155 kg。N、P、K比例为1∶0.32∶1.1。但根据当地农业生产实际和施肥经验,建议推荐早稻每公顷施肥量为氮肥140 kg,磷肥45 kg,钾肥135 kg。 相似文献

An optimized industry processing technology of peanut tofu and the novel prediction model for suitable peanut varieties 下载免费PDF全文
CHEN Bing-yu LI Qi-zhai HU Hui MENG Shi Faisal SHAH WANG Qiang LIU Hong-zhi 《农业科学学报》2020,19(9):2340-2351
Peanut protein is easily digested and absorbed by the human body, and peanut tofu does not contain flatulence factors and beany flour. However, at present, there is no industrial preparation process of peanut tofu, whereas the quality of tofu prepared by different peanut varieties is quite different. This study established an industrial feasible production process of peanut tofu and optimized the key process that regulates its quality. Compared with the existing method, the production time is reduced by 53.80%, therefore the daily production output is increased by 183.33%. The chemical properties of 26 peanut varieties and the quality characteristics of tofu prepared from these 26 varieties were determined. The peanut varieties were classified based on the quality characteristics of tofu using the hierarchical cluster analysis(HCA) method, out of which 7 varieties were screened out which were suitable for preparing peanut tofu. An evaluation standard was founded based on peanut tofu qualities. Six chemical trait indexes were correlated with peanut tofu qualities(P0.05). A logistic regressive model was developed to predict suitable peanut varieties and this prediction model was verified. This study may help broaden the peanut protein utilization, and provide guidance for breeding experts to select certain varieties for product specific cultivation of peanut. 相似文献
