近两年来,广陆矮4号作连晚栽培面积有所扩大,它有早熟、省肥、省专用秧田、产量较高的优点,并有利于扩种早稻,有利于后作春粮播种。但是,往往因气候条件和施肥管理方面不当,容易发生早衰,影响产量的提高。去年我们在晚稻生长后期,对广陆矮4号进行施粒肥试验,结果很好,有防早衰作用,增产显著。结果如下: In the recent two years, Guanglu Dwarf 4 has been expanded for even-late-night cultivation. It has the advantages of early maturing, provincial fertilization and provincial seedling production, and has the advantages of higher yield, expansion of early rice and post-spring spring sowing. However, often due to improper climatic conditions and fertilization management, premature aging is liable to occur, affecting the increase of output. Last year we were late in the late rice growth, Guanglu dwarf No. 4 granulation test, the results are good, with the role of anti-premature aging, a significant yield increase. The result is as follows:
