直播能够增产水稻的栽培方法,主要有直播法和移植法。移植法在世界水稻主要产区被广泛地采用着,而直播法,人们过云一直认为直播茎基入土浅,易倒伏,分蘖节位多,杆细穗短粒少,产量比移植低,肯定不能增产。同时,秧苗面积大,杂草多,不易管理。因而,直播水稻一直没有得到广泛地采用。但是,近几年来,无数直播栽培实际结果告诉我们,这种看法是不够全面的。要知道,过去直播水稻没有配合一系列直播栽培技术,而是在浅耕、肥少,稀植的条件下,采用移植的管理方法管理直播水稻,因而不能发挥增产的优越性。基于此点,只要在目前大力推广水稻密植、深耕多肥的条件下,采
Direct-seeded can increase rice cultivation methods, mainly live and transplanting method. Transplantation method is widely used in the main rice producing areas in the world. In the direct seeding method, people always think that direct seeding stems are shallow and easy to lodging, there are many tillers, fewer stems and short grains, and the yield is lower than that of transplanting Can not increase production. At the same time, large area of seedlings, weeds and more difficult to manage. Thus, direct seeding rice has not been widely adopted. However, in recent years, the actual results of numerous direct-seeded cultivation tell us that this view is not comprehensive enough. To know that in the past direct-seeded rice did not cooperate with a series of direct seeding cultivation techniques, but in the shallow tillage, fertilizer less, thin planting conditions, the use of transplanting management of direct-seeded rice, which can not give play to the superiority of yield. Based on this point, as long as the current efforts to promote close planting rice, deep plowing more fertilizer conditions, mining
