直播稻相对于移栽水稻而言,省去了育苗移栽环节,具有简化节本的特点。但在稻麦两熟种植制度下,直播稻生育期相应缩短。因此,直播稻品种要求生育期短、苗期早生快发、株型紧凑、耐密植、抗倒能力强。一、整地麦收后及时灭茬耕整田块,施足底肥,耙细、整平。开沟做畦,以利灌水和排除积水,做到排灌两便。直播稻一般要求种植在水稻田,不同于旱稻种植。二、播种麦收后宜抢时早播。沿黄稻区在6月15日前 Direct-seeded rice relative to the transplanted rice, eliminating the need for transplanting seedlings, with the characteristics of simplified section. However, under the system of rice and wheat double cropping, the growth period of direct seeding rice is correspondingly shortened. Therefore, direct seeding rice varieties require short growth period, early seedling quick hair, compact plant type, close planting, lodging ability. First, cut wheat field immediately after harvest closed stubble field, Shi enough fertilizer, rake thin, leveling. Trench ditch to facilitate irrigation and eliminate stagnant water, irrigation and drainage to do both. Direct-seeded rice is generally required to be planted in paddy fields, unlike dry rice. Second, sowing wheat harvest should seize the early broadcast. Along the yellow rice area before June 15
