摘要：

Fumigation of field soil with chloropicrin alone or followed by methyl bromide, each at 220 kg .cntdot. ha-1, released 20-30 ppm .**GRAPHIC**. which persisted for 75 days; such fumigation also doubled the amount of bicarbonate-extractable phosphate 28 days after fumigation. Soil fumigation increased both the vegetative and grain yields as well as increasing the content of N in the grain and the content of K and Cl in the tops at ear emergence. Root growth and the phosphate uptake activity of the roots were increased by soil fumigation.
