Tieli Rice Throwing Techniques And Weed Control Effect Study

Heilongjiang tieli grow rice has more than half a century of history, cultivation methods experienced a sow, live, dry density, ultra-high density and so fourth change, either cultivation methods, high-quality, high-throughput is our main problem at present in the production of ordinary seedling transplanting of seedlings on long, mechanical damage, seedling quality is not high on early growth of rice caused reproductive process delayed, late rice panicle rate is low, Spike, on high-yield rice obtained. In contrast, potted seedlings transplanted and inseminate technology can effectively avoid mechanical damage, slow-fast, seedling quality high, low section-spike tiller, rate, saving costs and many other features. Throwing rice as throwing into early, seedling small, high-transmittance, field and field the entire ground water early, early irrigation water discussion, more conducive to weed germination, growth and reproduction, easy formation weeds, as win high-yield rice throwing a major obstacle. For the sake of effective control of weeds, throwing rice production, cultivation, weed control, studies on rice throwing techniques have practical significance. Rice throwing technique has been widely used, but different weed species in regional Honda greater difference, by type of weed, design of experiments with different herbicides control efficiency analysis, rice seedling weed control technology.By tieli multipoint test show that the technology is better than rice save investment, than artificial planting rice province, provincial, provincial nursery; planting with shift, cold injury low ability, fat fast, growing Mong, population distribution is rational, photosynthetic efficiency high, panicle, high yield, workable, easy to learn, has a universal, high-yield, the goal of saving water, energy and formed a specific cultivation mode, has a strong practical and larger development space, and therefore very welcomed by the masses.Potted nursery seedlings and seedling, coupled with a bowl of perfect inseminate their defects, formed a complete cultivation mode, is the fusion of our ancestors ' traditional agricultural technology and foreign advanced technology suitable for my city of agricultural innovation techniques, is the city's traditional hand-intensive land use and modern mechanized agriculture combined development of a new form, fully embodies the scientific concept of development of agriculture is the realization of agricultural intensification of a specific procedure.Throwing related technologies introduction and promotion, for rice throwing in the area of application and extension is important. At present in order to achieve full series and automation machinery, we also need advanced technical and mechanical innovation efforts to make the gradual improvement of the production system. To further improve the guidance I, agricultural production, the city's food production levels promoted a new stair, cultivation techniques rise of a new phase. Because rice throwing back to seedling roots, shoots, field not Jianshui, the soil is moist State on weed especially Barnyard grass seed germination and growth of extremely favorable, weeds occur more than a normal number obviously transplant seedlings transplanted rice fields, and the peak occurs, ahead of weed growth field begomovirus time stretch, the harm to the rice. Agricultural weed control measures.â‘ the upland rotation, timely tillage, herbicide, ahead of evoked shovel Ridge Clearing Groove, net kind of impurity.â‘¡When throwing to strive to achieve a uniform, early fast fat, forming dense groups, suppressing weeds breeding.â‘¢use work in the fields of artificial uprooting weeds road. (2) chemical weeding. Weeds in the event of a serious need for chemical weed control in paddy field. Throwing before 5045 pharmacy closed early, throwing (throwing within 10 days after) application to control annual weeds; mid (tilling) application to control perennial weeds. Throwing up seedlings, throwing back 5-7 days is Honda intensive weed germination period, and grasp the opportunity to make a shallow layer of soil surface sealing application.
