三浆期保墒是播种保全苗的基础,是能否拿全苗的重要前提。整地的最佳时间短,特别是在今年春季我省干旱特别严重,旱像已成定局,土壤墒情差的情况下,我们要抓住暖流,及时进行连续作业,才能满足整地保墒的要求。所谓“三浆期”就是顶浆期、返浆期、临界浆期。“三浆期”保墒,是我国劳动人民在长期的生产实践中积累总结出来的行之有效的一种科学方法。就是针对“三浆期”土壤中水分活动规律,通过顶凌耙地、顶浆打垄、除净根茬、播后镇压等措施,达到保持住土壤墒情的目
Three paddy soil moisture is the basis for planting seedlings, is an important prerequisite to take the whole seedlings. The best time for site preparation is short. Especially in the spring this year, the drought in our province is particularly serious. Dry weather is a foregone conclusion and soil moisture is poor. We should seize the warm current and conduct continuous operations in time to meet the requirements of soil preparation and soil conservation. The so-called “three pulp period” is the apron, back to pulp, critical pulp. The “three pulp period” preserving soil moisture is a well-established scientific method that has been summed up by our working people in the long-term production practice. Is aimed at the “three pulp stage” soil water activity in the law, through the top Ling rake, apron to fight the ridge, in addition to net stubble, after sowing and other measures to suppress soil moisture to maintain the project
