红花是早稻主要肥源之一,提高红花鲜草产最,对夺取早稻高产有很大意义。据我们几年的试验表明,红花根外喷施微量元素和尿素,鲜草产量显著提高。1967年我们在本所沙土田上做了红花草喷施硼、钼肥试验,惊蛰边每亩红花田用硼酸、钼酸铵各 Safflower is one of the main fertilizer sources for early rice. It is of great significance to increase the production of safflower fresh grass and to capture the high yield of early rice. According to our years of experiments show that safflower roots sprayed with trace elements and urea, fresh grass yield increased significantly. In 1967 we made safflower grass spraying boron and molybdenum fertilizers on the sandy land of our institute, boric acid and ammonium molybdate
