  herbicides
2-C-methylerythritol phosphate pathway of isoprenoid biosynthesis as a target in identifying new antibiotics, herbicides, and im
      
MEP-pathway of isoprenoid biosynthesis is a promising target in identifying new herbicides, immunomodulators, and other physiologically active compounds.
      
This process was considerably stimulated by illumination and suppressed by the herbicides DCMU (an inhibitor of the electron transfer between quinones QA and QB in PS II) and methyl viologen (an electron acceptor from PS I).

棉花采用密植化学除草不中耕是当前棉花栽培另一种方法。它比早播、稀植、中耕多次的播种期晚30—40天,但提早拔秆15天左右,前后作物可以不套种。为了发挥群体增产作用,每亩密度为15000—20000株。早打顶,每株留3—4个果枝,主攻伏挑。前期用除草剂灭草,中、后期以密植控草,整个生育期不中耕。经我省连续5年多点试验和大面积示范证实,它可以克服我省3—4月播种时,低温多雨,烂种死苗和深秋低温多雨烂桃或不吐絮等不良气候的影响,能一播全苗,提高棉花品质;能避开前期棉蚜、地老虎和后期第四代棉铃虫的为害;还能调节棉花与小麦、油菜等春收作物及插早稻争季节、争劳力、争土地的矛盾,从而提高了土地利用率,争取粮棉、油棉双丰收。在同一品种,土、肥、水相当的条件下,棉花采用密植与化学除草不中耕相结合,除草效果达75—95%,其产量,一般比当地早播、稀植、多次中耕的增产两成左右。高的每亩产皮棉150—200斤。省工50%左右,降低成本20—30%。

Herbicide Ronstar has strong properties of controlling weeds. The efficiency of controlling weeds by Ronstar is above 90%. No side effect on N-fixation activity and plant characteristics in peanut has been found.

本试验说明,恶草灵除草能力强,除草效果在90%以上,对花生固氮活性及植株性状无不良影响.苗前喷施25%恶草灵0.2~0.3斤/亩,还可免去中耕.每亩喷药花不了半个工,比常规中耕约节省8~10个工,而产量与常规中耕基本相同.如花期能拔大草一次,则产量更高些.

It has been proved that higher rice yield would be resulted in seed broadcast sowing in minimum tillage field than in conventional method tillage field. Through continuous experiment of six times in three years, the average yield of rice has increased 5.1-14.7%. Seed broadcast sowing always gives higher yield than seedling planting either in minimum tillage or in thorough tillage field, always with increased yield to 4.96-15.3%.

It has been proved that higher rice yield would be resulted in seed broadcast sowing in minimum tillage field than in conventional method tillage field. Through continuous experiment of six times in three years, the average yield of rice has increased 5.1-14.7%. Seed broadcast sowing always gives higher yield than seedling planting either in minimum tillage or in thorough tillage field, always with increased yield to 4.96-15.3%. Some of the yield increased reasons have been studied from the standpoint of the physiological and ecological factors. Control the amount of seeds used in boadcast sowing is a very important measure to save seeds and to prevent or reduce rice plant falling over, thus a comparatively higher yield might be obtained. The technique to use the different kinds of herbicides, such as butachlor.benthiocarb and MCPA on seed broadcast sowing is also important.By adopting the minimum tillage and seed broadcast sowing method in rice field, one can heighten the labourproductlvity and so get a better economic benefit.

连续三年六造的试验表明,在只耙不犁的少耕田撒播水稻比在按传统方法又犁又耙的全耕田撒播水稻产量较高,增产率为5.1~14.7%。而在少耕田或全耕田撒播稻的产量又比插植稻高,增产率为4.96~15.3%,并从一些生理生态特性分析了产量较高的原因。通过试验还明确了控制播种量是防止或减少撒播稻倒伏并获得较高产量的重要措施,以及掌握了除草剂去草胺,杀草丹和二甲四氯在撒播田的施用技术。而调查研究表明,用少耕撒播法生产水稻比用传统耕作法生产水稻提高了劳动生产率和具有较好的经济效益。
