The rice direct-seeding technology enjoys peasant's welcome because of the advantage with reduction labour intensity and saving production cost.According to incompletely statistics, the area of the present Direct-seeding Rice of China has surpassed 2,000,000 ha (hectare).Make the rule of technology with industrialization and marketing development according to external rice, taking live is one of the important directions of China's rice cropping from now on.Developed countries such as America and Europe and Australia are after the seventies in 20th century, and under the drive of industrialization and urbanization, live modes are almost all adopted in the paddy rice plantation.At present, China's direct seading rice area also increases year by year.Can predict, along with the raising of China's Rice Production large-scale degree and the variation of rural laborer's structure, one of live main planting type that will become China paddy rice.
Along with the popularization of rice direct-seeding technology, soil is ploughed number of times and is obviously reduced, and it is also more and more shallow to plough the degree of depth, makes to drop in the procreation of can surviving of a small amount of weeds rice in field.Direct sowing rice field provides same control environment then for conventional japonica rice and weeds rice, and emergence rate of weeds rice and survival rate are improved greatly, makes weeds rice large tracts of land break out.In China, province (autonomous region, municipality directly under the Central Government) rice fields such as Heilungkiang, Jilin, Liaoning, the Inner Mongol, Hebei, Jiangsu, Anhui, Zhejiang, Hubei, Hunan, Jiangxi, Guangdong, Guangxi, Yunnan, Sichuan and Chongqing all have the weeds rice to take place.According to statistics, the loss that one of the living rice of the Jin of China Heilongjiang Province Lv descends and causes because of quality, at least 3 hundred million ~ 400,000,000 yuans of every year.Leizhou City, Guangdong nineteen ninety finds that direct sowing rice field takes place by the weeds rice, the littoral rice district large tracts of land generation of crossing a river in the south in towns such as Nan Xing town, this city, Song Zhu, Yang Jia in 1995 ~ 1999 years. the generation area reaches 0.8 ten thousand hm
2, the underproduction 70% ~ 80% that the general underproduction 20% ~ 30%. is serious, indivedual fields are lost and are received.
Since on the weeds rice form with physiology on all more similar with cultivated rice, limited the validity of selective chemical weed killer herbicide, further deepened the harm of weeds rice.The third careless amine is the chloroacetyl amine weed killer herbicide, suppresses weed growth through the synthetic of impede protein matter, and photosynthesis and respiration are had remote-effects.It has good preventive effect to the weeds rice, but simultaneously rice seedling is had very big poisoning.Now use Pretilachlor (Soft, Pretilachlor + antidote CGA12307) to control weeds rice, although this increase rice seedlings to Pretilachlor security, but because of weedy rice has absorbed understanding agents, making its anti-only about 50% efficient.
Be directed to the problem of the third careless amine to rice safety property, Cao Yongsong etc. (number of patent application: 96118409.4) and Huang Xiangyou etc. 200710068374.7) etc. (number of patent application: more than ten patent all has and relates to.Though above-mentioned patent can improve the safety of rice seedling to the third careless amine, for the controlling weeds rice, improved the drug resistance of weeds rice simultaneously to the third careless amine, make that control efficiency reduces greatly.Do not see at present the special direct seading rice seed soaking agent that can improve rice seedling as yet to the safety of the third careless amine.
