采用塑料软盘育秧,小苗带土抛秧栽培,是近年来水稻生产上新兴起的一种栽秧方式,它集省工、节本、高产、高效等诸多优点于一体,在我国的稻作生产上具有广阔的应用前景。生产上使用的塑料育秧软盘规格为长50厘米、宽30厘米、每盘有468个孔钵,目前市售价每个0.60元。若每亩栽秧2.5万穴,则需盘60个,每个盘可重复使用3—4次,故每亩秧盘成本为9—12元。采用塑料软盘育秧,不仅秧苗素质好,具有明显的增产效果,而且可省去70—90％的秧田,并可免掉人工拔秧、插秧等环节,所以每亩可节约开支40元以上。其栽培技术要点如下: 一、选用抗倒品种。抛秧稻比插秧稻扎根浅,容易倒伏,因而必须选用株高适中,茎秆粗壮的抗倒品种。二、培育适龄壮秧。 1.钵土的准备。取肥沃、无杂草种子及碎石、杂
The use of plastic floppy seedling, seedlings with soil throwing seedling cultivation, rice production in recent years is a new way of planting seedlings, which set the provincial workers, section, high yield, high efficiency and many other advantages in one of the rice production in China Has a broad application prospects. The production of plastic seedling raising floppy disk specifications for the length of 50 cm, 30 cm wide, 468 per dish mortar, the current market price of 0.60 yuan each. If planting 25,000 acre per acre, you need to plate 60, each plate can be reused 3-4 times, so the cost per acre plate 9-12 yuan. The use of plastic floppy seedling, not only good quality seedlings, with a significant increase in yield, and can save 70-90% of the seedling, and can be exempt from artificial poplar, transplanting and other sectors, so the cost per acre can save 40 yuan or more. The cultivation techniques are as follows: First, the choice of anti-down varieties. Throwing rice than rice transplanting shallow root, easy to lodging, which must be selected moderate height stalks stalwart varieties. Second, nurturing age-strong seedling. 1. bowl soil preparation. Take fertile, no weed seeds and gravel, miscellaneous
