From 1959 to 1963,investigations have been made on the planting experiences of ChenYueng-kang——the well known rice specialist,in obtaining higher production of late rice.In these five years,out of 23 high productive sites cultivated by him,21 sites having rangedfrom 456-628 kg per mou(1/15 hectare).The practical cultivation method has been carriedout in a state farm since 1962,and also applied on the Peoples Commune fields in 248places for demonstration in Su-chou distriet of Kiangsu province since 1963,and it showedsignificant increase of production ranging from 11-23%.After transplanting,technical performance in various growing stages has to be planned inline with the high yield object,with which the help of technique by controlling the growth anddevelopment of rice and the proper fluctuation of the leaf-shade in order to obtain an“idealplant”for highest production.In the period of tillering,leaf-shade is required for dark greenin color(leaf-shade in dark color for the 1st time)but the number of plants,length of culmsand leaf-area index have to be controlled within a certain limit in order to maintain a steadygrowth.For instance,for the variety“Lao Lai Ching”,the total number of plants per Chinesemou(666 m~2)may be limited in 300 thousands,the length of culms is 67 cms.at the end oftillering stage and 130-133 cms.when ripening,and the leaf-area index is 2 approximately atthe climax of tillering stage(about one month after transplanting).After draining,theleaves then become again lighter in color for yellowish green.At the same time,the leaves becomeupright.On this base,the fertilizer is applied,and the leaves appeared to be dark for thesecond time.Henceforth,again it turns into light colored before the ear-(?)rimordia formation.It is also important that the plants look both flourishing and tough or stout.The plants thenbecome“row clesed”(i.e.leaves of adjacent rows overlap each other)10 days after the ear-primordia formation.The optimum highest leaf-area index is about 6—7.During the begin-ning of ear formation,fertilizer is again applied in accordance with the state of plants toavoid early decayed.The leaf-shade turns into dark green for the third time.Before heading,it gradually turns lighter and becomes yellowish green for the third time.Before ripening,the culm is fresh and the grain is yellow,without any lodging and outburst of blast disease.In this report,some explanation is given for controlling the growth of the plants aimingat an“ideal plant”in various growing periods.The function played by the initial technicalperformances is also analyzed.It is shown that the fluctuation pattern of leaf-shade has todo with the change of nitrogen and carbohydrate content which effect directly to the growthof organs and therefore the formation of grains.According to analysis,it is also pointed out that the regulation of the fluctuation of leaf-shade may be.used as one of the criteria for controlling the metabolic activity between carbonand nitrogen.But it should be proceed together in a controlled manner for an“ideal plant”growth,which may be successful in ap(?)lying a sufficient amount of fertilizer and can bethoroughly utilized by the plants without causing any lodging and outburst of blast disease.
