1.宁夏灌区7月初已进入盛夏,多数年份有暴风骤雨,有时并伴随青干,在此期以前,即在小麦成熟前15天左右灌麦黄水,不仅能促进灌浆进程,而且可以改善田间小气候,增加土壤湿度,增强对青干的抗性,达到增产的目的。 2.在伴有青干天气出现的情况下,采用硼酸浸种,以及喷施硼酸、草灰水、石油助长剂、硫酸铜等五个处理具有增产效果,其穗粒重或籽粒重都有不同程度的增重作用。 3.在化学处理的方法上,生育期间喷洒比浸种处理的效果好,表现籽粒灌浆速度日增重较多,灌浆日期增加,停止灌浆期推迟,达到提高经济系数与籽粒增重的目的。 4.在化学处理喷施的条件下,对墨卡品种的麦穗发育有一定的增粒作用,特别对顶部一、二小穗在不同处理间可多结实0.3～1.2粒。
1. Ningxia irrigation area has entered into early summer in early July, with heavy rains in most years and sometimes accompanied with greening. Prior to this period, irrigating yellowish water about 15 days before wheat maturation can not only promote the filling process, but also improve the microclimate in the field , Increase soil moisture, enhance the resistance to green stems, to achieve the purpose of increasing production. With the emergence of dry weather, the use of boric acid soaking, and spraying boric acid, grass and gray water, petroleum boosters, copper sulfate treatment of five have the effect of increasing yield, grain weight or grain weight has varying degrees The role of weight gain. 3. In the chemical treatment method, spraying during the growth period is better than the soaking treatment, which shows that the grain filling rate increases more daily, the filling date increases and the stopping filling period postpones, so as to improve the economic coefficient and grain weight gain. Under the conditions of chemical treatment spraying, there was certain granulation effect on the development of wheat varieties of Moke, especially for the first and second spikelets can be 0.3 to 1.2 grains in different treatments.
