1986-1988年9个试点的春花生试验表明:花生始花后25-30天喷施25-100ppm pp_(333)溶液或300-500ppm粉锈宁溶液可分别增产7.0%和10.0%左右。中等以上肥力,植株生长旺盛的田块增产;地力低,植株生长差的田块无效。这两种药剂之所以增产,是由于抑制主茎及分枝营养生长,将光合产物集中分配到荚果;同时,粉锈宁还可增加后期青叶数,形成较多光合产物。试验药剂成本低,增产增收。 The spring peanut experiments of 9 pilot plots from 1986 to 1988 showed that spraying 25-100ppm pp_ (333) solution or 300-500ppm triadimencinil solution could increase the yield by 7.0% and 10.0%, respectively. Middle above fertility, strong growth of plants yield plots; low fertility, poor plant growth plots invalid. The reason why the two agents increase production is due to the inhibition of the main stems and branches of vegetative growth, the photosynthate will be distributed to the pod; At the same time, the triadimefon may also increase the number of late leaflets to form more photosynthetic products. Experimental reagents low cost, increase production and income.

传统的应用题教学是小学数学教学的重要部分,新课标把其改为“用数学”和“解决问题”,不再单独编写,而是分散在数与代数、空间与图形、统计与概率、实践与综合运用等四个领域的教学过程中。如何搞好“解决问题”教学呢?笔者认为要抓好以下几个关键环节。    一、观察主题图,收集信息    收集信息是解决问题的第一步,也是必需的环节。新教材中“解决问题”的呈现信息方式是多样化的:有以主题情境图方式呈现的,也有以

音乐教学中的美育教学主要是通过艺术形象去感染儿童的心灵,启迪儿童的心智,从而去美化儿童的内心世界,培养健康的心理品质。我们在培养学生感受音乐、表现音乐等能力的同时,还要利用音乐的美育教学,适时激发学生的思想情绪,充分调动其积极的因素,因势利导,使其自觉树立一种生活的信念,即对美好未来的追求,由此可见,把美育融于音乐教学之中是多么的重要。    一、在教学中认识美    法国作曲家圣桑说:“音乐不是
