种衣剂拌种对小麦病虫害的防治效果   总被引：6，自引：0，他引：6  

王海燕  张忠山 《华北农学报》1994,9(2):115-119

研究表明，种衣剂拌种比不拌种的晚出苗１－２天，但出苗整齐，麦苗矮壮；种衣剂拌种可明显推迟小麦白粉病的始发期，并减低其在田间的流行速率和强度，抽穗开花期防效仍在９０％以上；对小麦秆黑粉、条锈病、纹枯病和地下害也有一定防效；种衣剂拌种比不抖种的小麦穗粒数增加７．７－１３．９位，千粒重提高３－７ｇ，每公顷增产达１５．３－４４．９％；以种衣剂１４号（２２％）的效果最好，种衣剂１４号（８％）次之。  相似文献

磷酸铁盐涂层: 控制黄铁矿氧化的新手段     

HUANG Xiao  V. P. EVANGELOU 《土壤圈》1997,7(2):103-110

A novel coating technique was develped for controlling pyrite oxidation .The technique involved leaching pyrite particles with a solution containing low concentrations of phosphate and hydrogen peroxide.During the leaching rpocess,the iron released from pyrite by hydrogen proxide was precipitated by phosphate as a ferric phosphate coating .This coating was shown to be able to effectively prevent pyirte from oxidation and it could be established at the expense of only surface portions of pyrite.The emergence of this technique could provide a unique potential route for abating acid mine draingage and reclaiming sulfide-containing degraded mining land.  相似文献   

Combined effects of sodium chlorite dip treatment and chitosan coatings on the quality of fresh-cut d’Anjou pears     

Zhenlei XiaoYangchao Luo  Yaguang LuoQin Wang 《Postharvest Biology and Technology》2011,62(3):319-326

This study evaluated the effects of sodium chlorite (SC) alone and its sequential treatment with edible coatings on browning inhibition and quality maintenance of fresh-cut d’Anjou pears. Edible coatings were prepared from chitosan (CH) and its water-soluble derivative carboxymethyl chitosan (CMCH), separately. Pear wedges were immersed in SC solution, followed by coating with CH or CMCH solutions. The samples were packed in unsealed bags and stored at 4 °C for subsequent color, firmness, and weight loss measurement. The effects of the SC and coating treatments on polyphenol oxidase (PPO) inhibition and microbial inactivation were also evaluated. Results indicated that SC exhibited significant (P < 0.05) inhibition of browning and PPO activity. The SC treatment was also strongly effective in inactivating Escherichia coli O157:H7 on pear slices. Coating SC-treated pear slices with CH adversely affected the quality of pear slices by accelerating the discoloration of cut surfaces and increasing the PPO activity. On the contrary, coating SC-treated samples with CMCH significantly prevented the browning reaction and inhibited PPO activity. In addition, SC and CH/CMCH coatings maintained tissue firmness and did not affect weight loss. Our study may provide a scientific basis for the use of SC + CMCH treatment as an alternative preservation treatment for fresh-cut fruits and vegetables.  相似文献   

不同浓度蜂蜡涂膜剂对台湾青枣保鲜效果的影响   总被引：1，自引：0，他引：1
