This paper aims to find out the nutrition characteristics and fertilizer absorption rule of Castor in arid red soil districts under the subtropical climate of Yunnan province, and establish a corresponding fertilizing technology under the condition. It choose the variety TCO-202 of Castor (Ricinus communis L.) as test material to observe and record the dry matter accumulation of each organ as root, stem, foliage and inflorescence, which are in the five critical growth stages as seedling stage、 bud stage、 blooming stage、 filling stage、 maturation stage of Castor {Ricinus communis L. respectively, and measure out the fertilizer absorption amount of nitrogen, phosphorus and potassium.

本文以云南北亚热带气候下的红壤旱地为试验条件，选用蓖麻品种TCO-202为试验材料，通过对苗期、现蕾期、开花期、灌浆期、成熟期五个蓖麻生长关键时期根、茎、叶、花序各器官的干物质积累和氮、磷、钾吸肥量的测定，研究云南红壤上蓖麻的营养特性和吸肥规律；依据蓖麻的营养特性和吸肥规律，结合云南红壤氮、磷、钾的含量与利用效率，制定适合云南红壤上蓖麻栽培的施肥技术研究方案。

This paper studied the dynamic pattern of nutrient components of cluster leaf rosinweed at different growth periods.

测定串叶松香草在叶丛期、抽苔期、开花期和成熟期的营养成分含量，同时选择装有永久性瘤胃瘘管的小尾寒羊与杜泊羊杂交一代羊6只，测定各生育期常规营养的瘤胃降解动态。

Givennutrient components, rumen degradation characteristics and output, it's advisable that cluster leaf rosinweed be utilized between stem elongation to flowering stage.

综合考虑串叶松香草不同生育期的营养成分、瘤胃降解动态及产量，建议在抽苔期至开花期刈割利用为宜。

Based on the field experiments in 2000~2004, the yield of 2-year-old herbage was determined from the heading stage to the flowering stage and the relativities between the yield and 3 climate factors (including precipitation, sunlight and temperature) were analyzed by scatter diagram and linear regression method.

方法］通过2000~2004年的田间试验，在抽穗至开花期测定2龄牧草的产量，通过点聚图与线性回归法分析青海老芒麦草产量与3个气候因子的相关性。

Spraying KCL solution every other day for 15 days start from late flowering, results showed that nitrate content in the leafs and stems were markedly reduced, Nitrogen redistributed to silique and rapeseed were efficiently promoted, nitrate reductase activity in the leaf were markedly increased. The differences of the same species which under different treatment are more serious, and the differences of the different species which under the same treatment are more significant.

结果表明，喷施氯化钾溶液能有效降低开花期和收获期油菜茎叶硝酸盐含量，与喷施硫酸钾溶液和清水相比达到了显著水平；有效促进了氮素向角果和籽粒分配，显著增强了油菜角果初期叶片硝酸还原酶的活性；同一品种不同处理之间的差异比较显著，品种之间处理后的差异也比较明显。

The main results are as follows:(1) Strong allelopathic effects of Solidago canadensis in flower period were observed, with facilitating effect on growth of crop seedling under treatment with 25 mg?

结果表明：(1)处于开花期的加拿大一枝黄花存在明显的化感作用，在25mg？

The effects maceration extract from Solidago canadensis in flower period on seed germination and grow of three crops including Capsicum annuum, Lycoperiscum esculetum and Braxxica chinensis var.

测定了入侵杂草加拿大一枝黄花开花期的茎、叶和花序水浸提液对辣椒、番茄、长梗白菜Brassica chinensis var。

Different treatments have remarkable effect on green area of stem, leaf and spike and their proportion.

不同处理对穗、茎和叶器官的面积及其比例，也产生显著影响；在不同栽培条件下，开花期非叶光合器官占总绿色面积的比例在61.33%~62.69%之间。

In order to understand nitrogen accumulation and distribution in sweet maize variety with high fresh ear and kernel yield, explain the genotypic differences of N accumulation and distribution at different growth-phases and their effects on yield formation and N utilization efficiency, 22 sweet maize (Zea mays L . saccharata Sturt ) varieties released in recent years in China were planted and their N accumulation and distribution amount at jointing stage, silking stage and fresh stage under the same nitrogen level were studied.

为了解甜玉米高产品种氮素积累和分配的规律，阐明不同生育阶段氮素积累和分配的基因型差异，及其对产量形成及氮素利用效率的作用，分析了22个甜玉米品种在同一施氮水平下拔节期、开花期和鲜食期的植株氮素积累量和分配量。

Heterosis for fructan accumulation and content,tissue nitrogen accumulation and content in various growth stages of six hybrids was studied at the University of Sydeny, Plant Breeding Institute, Narrabri in 1996 season.

果糖积累的杂种优势与籽粒产量、籽粒氮产量和含量优势一般无显著相关关系；开花期和灌浆末期植株果糖含量的杂种优势正相关于籽粒产量优势，负相关于籽粒氮含量优势。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.
