Early Indica “Guanglu Dwarf No. 4” is Guangdong Provincial Academy of Agricultural Sciences with the “Square Dwarf 3784” and “land Choi” hybrid breeding selected into. Introduced in 1969 my field trial, 1.35 acres of this inserted single breeding fields, 695 kg per mu, the performance of stalk straw, high yield. Since 1970, Tongxiang County seed base team to further expand the model trials; three years to expand the planting results, showing stable yield, high yield, the general green manure even for the early rice per mu 700-800 kg, compared to the short leg Nantes, Pioneer 1 5- 10%, in the foot fat, close planting conditions, a greater yield increase. My field planted 29.2 acres in 1970, under the cultivation conditions of a small plug, the average yield of 685 pounds per mu; 1971 129.3 acres
