旱育稀植是我县今年重点推广的水稻增产增收新技术。为了制定一套最适合我县的水稻旱育稀植实用技术规程，我什1对水稻旱育秧直接栽人大田的增产效果，以及大田的适宜栽插密度进行了试验研究。试验表明在同等栽培条件下，杂交水稻采用旱育秧直栽大田技术，一般可比常规水育秧增 Drought and sparse planting is my county this year to promote rice production and income of new technologies. In order to formulate a set of practical technical regulations that are most suitable for rice cultivation and sparse planting in our county, we conducted a pilot study on the yield-increasing effects of direct cultivation of rice dry seedlings on field and field planting density. Experiments show that under the same cultivation conditions, the hybrid rice with direct cultivation of dry nursery seedling field technology, generally than conventional watering seedlings
