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

摘要:

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。

Abstract:

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.
