According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

根据多年的生产实践，从科学育苗、栽培管理、售前处理和病虫害防治等方面综合总结了叶子花的规模化矮化促成生产技术措施：选择泥炭土、蛭石和黄沙按3：2：1比例混合均匀的扦插基质，采用半木质化当年生枝条，剪成5~10cm长的2~3叶节一段，沾染1%自制生根粉的扦插育苗较组培育苗成本低，成活率高；结合修剪用2~5g/L的多效唑进行叶面喷洒能有效控制生长，矮化植株；选择2.5~4.0的丁酰肼叶面喷洒和每天保持不多于11h的短日照处理，能有效促进开花；销售前全株喷洒脱50mg/L NAA可延长花期20天左右；整个生产过程加强肥水管理、温湿度控制和环境清洁能有效防治病虫害发生。

Harmless-pear production in the early 1970s in the 20th century on by some countries, the importance pome fruit production on the environment and inputs to the implementation of strict control and monitoring, to investigate the cultivation of scientific ISO Technical Specification, formulated in line with the reality of their own sets of regulations and systems to ensure that producers, the interests of consumers and the environment for sustainable development.

无公害梨果生产早在20世纪70年代就受到了一些经济发达国家的重视，对梨果生产的环境和投入品实行严格的控制和监测，探讨出科学的标准化栽培技术规程，制定了符合本国实际的成套管理法规和制度，以确保生产者、消费者的利益和环境的可持续发展。

So it needs improving or alternating urgently. Some good germplasms for rootstocks for citrus have been picked out and introdcted into. Some somatic hybrids used as rootstocks have been selected through somatoplasm fusion. Some methods in early identification on stability of inherence and copatiblity and dwarf are explored, and they need improving. Rootstocks having some virtues have been selected, but they cannot take the leading place of trifoliate orange. The research method that the rootstocks are only compared with each other should be altered into that the rootstocks and given control measures or environmental conductions are connected to make the rootstocks compared with each other.

在砧木选择研究进展上，中国调查出和引进了一些优良的柑橘砧木种质资源，通过体细胞融合选育出一些可作为柑橘砧木的柑橘体细胞杂种资源；在柑橘砧木资源的遗传稳定性、嫁接亲和性和矮化性等早期鉴定上，探索出一些有待完善的鉴定方法；在砧木选择上，选出一些具有某些优点的砧木，但尚不能冲击枳砧的主导地位，并且选择研究方法有必要把现行单纯的砧木比较改为与砧木种类、栽培技术或环境条件相结合进行比较。

Some technological measures to improve the quality of seedling in establishment cultivation, including the technology of seed treatment, the control of environment condition and the use of plant growth regulators to prevent spindling, were discussed in this paper.

In 2003, the wineries and wine growers in California developed "Code of Sustainable Winegrowing Practices". This code promotes farming and winemaking practices that are sensitive to the environment and responsive to the needs and interest of society in general.

2003年，加州的酒商和葡萄的栽培者制定了"可持续葡萄种植和葡萄酒酿造工艺代码"，这个规定耕作和酿造实践对环境非常的敏感，需要全社会对耕作和酿造工艺的关注。

In addition, the specific POD band (Rf = 0.67) of C. hytivus and C. hystrix was detected in each individual of population, which indicated this band could be a good biochemical marker for monitoring the flow of germ plasm from C.

另外， 新种与野生种的特征性POD酶带(Rf=0.67)在群体内各单株内都有表达，这表明该带可作为一个稳定的生化标记在监控新种的遗传物质向栽培黄瓜的流动中发挥作用。

According to the study result of species selection,12 species of Eucaly-ptus and Acacia were introduced in 1993 in Yuanmou of Yunnan Province Through observing and analysing for more than 2 years and comparing the adaptability and rapidly-growing ability with Leucaena lecocephala introduced successfully before the authors found that Eucalyptus camaldulensis,A auriculiformis ,A caciamangium were the optimal afforestation species in dry-hot river valley of Yuamou This had certain significance to guide...
