| 1. | In this paper , a new cultivation practice ( super - sparse - cultivation associated with maximum - tiller seedling , sscmts ) of hybrid rice was proposed and its high - yielding mechanism was studied
摘要以5个杂交中稻品种为材料，对作者提出的“杂交中稻超多蘖壮秧超稀高产栽培技术”的高产原理及技术进行了5年的研究。 |
| 2. | The effects of different tillering position and number on heading date of the hybrid rice shanyou 63 were studied under the condition of potted artificially controlled by the removal of tillers on specific nodes
摘要以汕优63为材料，研究了在盆钵栽培条件下人工去蘖形成不同节位、不同数量分蘖的处理对抽穗期的影响。 |
| 3. | The vegetative tiller can produce more buds than the reproductive tiller on hordeum brevisubulatum population , and the age structure of bud from either vegetative tiller or reproductive tiller is an increasing model
野大麦种群营养蘖分蘖节的营养繁殖力比生殖蘖强，营养蘖和生殖蘖上芽的组成亦均为明显的增长型年龄结构。 |
| 4. | The reproductive tiller is obviously higher than the vegetative , and there is little difference among all of age classes reproductive tiller at height and biomass , but the vegetative tiller is decreasing with the increasing age class
生殖蘖明显高于营养蘖，但各龄生殖蘖的高度和生产力差异不明显，营养蘖随着龄级的增加而明显下降。 |
| 5. | Many spikelets and good grain - filling were the direct factors for the high yield of sscmts in hybrid rice , and those high - yielding factors relied on high quality seedlings , sturdy individuals , high quality population and vigorous later growth
“两超”栽培高素质的“超多蘖壮秧”和本田期健壮的个体生长是其穗足、穗大粒多的前提，而其高质量的群体结构和明显的后期生长优势是其籽粒灌浆结实良好和单穗重提高的物质保证。 |
| 6. | The results showed that yield structure of the middling population treatment were the most excellent as a whole and its grain yield was the highest among the three treatments , while the dynamic of tiller and its formation into panicles , root - bleeding intensity / spikeltes , lai and its structure , dry matter accumulation and transportation were the most reasonable too
结果表明，中等群体处理的产量结构最优，在三处理中稻谷产量最高，其茎蘖消长与成穗、颖花伤流量、叶面积系数与结构以及干物质积累与转运总体上最为合理。 |
| 7. | Bud is produced in both rhizome and tiller - node , rhizome can produce more buds than tiller - node on hordeum brevisubulatum , arundinella hirta , calamagrostis epigeios , c . rigidula and hierochloe glabra populations . both 1st age rhizome and tiller - node of 1st age tiller are mainly two contributors in importing of bud bank
根茎和分蘖节是芽的主要产生部位，牛鞭草、野古草、拂子茅、硬拂子茅和光稃茅香种群根茎的营养繁殖力比分蘖节强， 1龄根茎和1龄分蘖株分蘖节是芽库输入的主要贡献者。 |
| 8. | Based on visual rice growth models ( vrgm ) and with rice tillering as examples , the back - propagation artificial neural networks ( bp ) and radial basis function networks ( rbf ) were established to simulate the rice growth and to compare with statistical model and dynamic model
3 、在研制可视水稻生长模型的基础上，进一步利用人工神经网络bp模型和rbf模型，对水稻生长进行了模拟与仿真。并以水稻群体茎蘖动态为例，与水稻群体分蘖的统计模型和动力学模型进行了比较。 |
| 9. | Tillering and earbearing characteristics of wheat varit ies “ miannong 4 " and “ miannon 3 " were studied under three densities . the results indicated that t he two varieties had medium tillering speeds and tillering numbers ， and their t illering number under medium density was 3 . 7 tillers per plant ， which is less th a n that of “ mianyang 11 " ， a popular wheat variety in sichuan in 1980s . their perc en tage of earbearing was about 55 % ， which is also lower than that of “ mianyang 11 "
在3种密度下对绵农4号、绵农3号的分蘖及成穗特性进行了初步研究，结果表明：绵农4号、绵农3号的分蘖速度和分蘖力皆为中等，中等密度条件下，有效分蘖期每天可形成0 . 15蘖，各期总蘖数为3 . 7左右，低于绵阳11号；与绵阳11号分蘖速度的差异主要在有效分蘖期；绵农4号、绵农3号的成穗率为55 %左右，低于绵阳11号；但分蘖和主穗的差异较小，分蘖穗重占主穗重的80 %左右，茎蘖穗重变异系数15 %左右，穗子大小均匀一致，小穗相对较少，小穗较大，这些性状都优于绵阳11号。 |
