水稻稀植、超稀植栽培高产生育模式及促控枝术的研究──Ⅰ．水稻早熟品种公顷9000公斤产量的营养生长模式

STUDIES ON HIGH YIELD GROWTH MODEL AND PROMOTE OR CONTROL TECHNIQUE OF RICE IN SPACED PLANTING CULTIVATION ──Ⅰ. VEGETATION GROWTH MODEL OF YIELD ABOVE 9000KG/HA OF EARLY VARIETIES OF RICE

本文报导了三种类型（穗数型、穗重型和中间型）的早熟粳稻品种（松前、通２４—１和通系１１２），在５种栽培条件下（３０．０ｃｍ×１３．３ｃｍ，３０．０ｃｍ×２０．０ｃｍ，３０．０ｃｍ×２６．６ｃｍ，４０．０ｃｍ×２０．０ｃｍ．５０．０ｃｍ＋３０．０ｃｍ×２０．０ｃｍ）公顷９０００公斤产量的营养生长模式（即：株高、叶龄、叶龄指数、茎数、生长量、鲜重、干重和叶面积指数），总结了不同栽培方式的水稻群体营养生长期的性状差异。

The vegetation growth model, e. g. hight of plant, leaf age, leaf index,stems,increment, fresh and dry weight, leaf area index,of 9000kg/ha yield of three early varieties (Ma tsumae, Tong 24-1 and Tongxi 112) with the types of spike number, ear wight and passage form of rice at five cultivation patterns (30. 3cm ×13. 3cm, 30. 0cm ×20. 0cm, 30. 0cm ×26. 6cm, 40. 0cm ×20. ocm, 50. 0cm +30. 0cm ×20. 0cm ) have been reported. And the charater difference of vegetation growth period of rice colony in different cultivation patterns is also summarized in this article.
