四、整地与插秧1.耕翻耕翻地以秋翻不耙、晒垡为宜,新开的水田、草甸地、洼地和盐碱地均应进行秋翻,不能进行秋翻的地块应抢早进行春翻,以晒垡提高地温。耕翻深度以12—16厘米为宜,盐碱地还可深一些。水田旋耕不仅作业质量好,而且省工、省水,可节约泡田用水约20%,也很适合小井种稻。2.整地经秋翻的新开水田,应在垡块化冻7—8厘米或在垡块化到一半以上时,用圆盘耙把垡块耙碎,然后筑池埂,灌水泡田5—7天再进行水耙。春翻的地块应及时进行耙地并应及早灌水泡田进行水耙。由于小井的出水量有限,灌水泡田应提前进行,泡好一块,耙一块。
Four, land preparation and transplanting Rice plowing, plowing and tillage to autumn turning rake, sunning appropriate, the newly opened paddy fields, meadows, depressions and saline-alkali land should be carried out autumn turn, can not be autumn turn plots should be robbed As early as the spring turn, to improve the ground temperature sun. Plowing depth to 12-16 cm is appropriate, saline-alkali can be deeper. Rotary paddy field not only good job quality, and provincial workers, water, water savings of about 20% of the field, but also very suitable for small wells rice. 2. The whole land open fall paddy fields should be frozen in the block 7-8 cm or in the block into more than half, with a disc harrow block rake broken, and then build ponds, irrigation foam field 5- 7 days to re-water rake. Spring turn the plot should be promptly harrowed and should be irrigated early field of water rakes. As a result of a limited amount of wells, irrigation bubble fields should be carried out in advance, soak a piece of rake.
