1.科学管理分蘖始期至有效分蘖终止期,始终要浅水灌溉,水深3厘米左右。如是井灌,应设晒水池或延长水路,提高水温后灌溉。 2.喷施保蘖肥在分蘖末期6月25日—30日,秧苗如表现缺肥症状,主茎数仍未达到预期茎数,可适当喷施保蘖肥。一般占总氮量的10%,即每公顷施硫酸铵75公斤。如基肥、分蘖肥多,分蘖旺盛不必施保蘖肥。 3.除草此时在施除草剂的基础上,进行1—2次工人除草。
1. Scientific management From the beginning of tillering to the termination of effective tillering, always shallow water irrigation, water depth of about 3 cm. In the case of well irrigation, should be set up basins or extend the waterway to increase water temperature after irrigation. 2. Spraying tilting fertilizer at the end of tiller June 25 -30 days, such as the performance of seedlings lack of fertilizer symptoms, the number of main stem has not yet reached the expected number of stems, fertilizers may be appropriate to spray tillering. Generally 10% of the total nitrogen, that is, 75 kg of ammonium sulfate per hectare. Such as basal, tillering and more fat, strong tillers do not need to ensure tillering fertilizer. 3. Weeding at this time in the application of herbicides, based on 1-2 workers weeding.
