1、protected (structure) horticulture is defined as a cultivation method taking u of heat即兴演讲题目
keeping ,chilling prevention or cooling and rainproof facilities to prevent the crops production from being influenced or riously done by natural asons and to artificially create a microclimate
environment suitable for growing horticultural crops in cold or hot weather hat actually unfavorable to the crop development .it is also termed as out-of-ason culture ,ason-off culture or forcing
culture .becau of the ason in which horticultural crops are planted is hand for their growing in
open field.
2、Windbreak、cold –frame 、hot-frame、 plastic-clad tunnel and greenhou could provide a variety给某人打电话的英文
of vegetable eding for open field or protected culture or protect eding of cold tolerant vegetable living through the winter ,for early planting and acquirement of early mature products.
3、In respect of structure type, the largest horticultural structure area in our country consists of plastic
tunnels and lean to hous, especially the energy-sawing solar greenhou, which has become the
dominant greenhou type in the country. Prently the development of large greenhou or multi-
span hou has been initiated.

4、In horticultural crop cultivation under structure the key point of environment management for
托福考试内容growers is to create optimal complex of environmental conditions for crop growth and development, as possibly as they can, according to properties and environmental demand of crop.

1、most soil amendments are consisted of the increasing of organic matters ,addition of specific
nutritional elements and ph adjustment
allen什么意思2、the soil is an important constitute of the land loamy soil must consist of soul particles with proper
ratio ,with equilibrium of nutrients ,in which contains some organic matter ,and with considerable
moisture

Lesson6 part A
1、sink demand of horticultural crops extremely affects photosynthetic ,for example ,leaf photosynthesis
noticeably decrea when potato tubers are removed during their growth short-term respon may be stomato clo effect ,but this cannot explain common continuous effects ,sometime when the sou
烦恼的英文rce-sink ratio increas significantly ,some old leaves can renew their photosynthesis functions ,on the other hand ,rapidly growing sinks sometimes compete with leaves for mobilizable nitrogen and this results in abscission of leaves and lower photosynthesis capacity.英语副词
2、It is not clear yet that how the sink demand affect photosynthesis of leaves .the simplest explanation
is that photosynthesis accumulated in leaves restrain photosynthesis . however trials for examining
this hypothesis usually obtained the opposite results .furthermore ,in practice ,photosynthates emly not accumulate beside chloroplasts in mesophyll cells .thus ,more rearch work should be done on source-sink relationship to improve yields of horticultural crops
Lesson7 part A所望
1、the development of horticultural crops product organs consist of maturity 、full ripeness and
nescence stages .maturity includes physiological ripeness and horticultural ripeness the former
means that in the last growth stage ,mature organs become full ripening and the later means the be
st growth stage of horticultural crops for harvest ,such as leaf vegetables ,when they are reaped ,they are not physiological ripe ,and flower crops are harvested when thy flower.
Full ripeness is the develop stage after fruit mature some fruits can get full ripeness in trees ,while some must ripen after parated from trees .after full ripen the flesh mealiness aroma strength proper acidity and sugar ,nescence is a stopping terminating process of living activity. In this stage,
product organs quality of horticultural crops become bad and completely leaves their economical
value in the end
Lesson8 part A
1、hormone produced by ed influence fruit tting ,fruit growth and the balance of hormones in plant
2、Stone fruits can no t t their fruits when their embryos develop abnormally. pome fruits can t
without eds ,but flesh cells grow slowly
3、Gibberellins was produced after pollination with ed development gibberellins promotes synthesis
of auxin , therefore ,promotes fruit tting .the fruit t and fruit growth is similar between the ovule not pollinated treated by gibberellins and tho which has ed
4、Gibberellins produced by apple eds apparently restrain flower differentiation and result in alternate
fruiting .alternate fruiting is not normal in pear and many stone fruits .it is becau the early
occurrence of gibberellins synthesis peak which is not concurrent with flower differentiation
initiation.
Lesson13 part A
1、pruning of fruit trees is a practice involves the heading back cuts and the thinning cuts of branches
for good framework ,for regulating contradiction between growth and fruiting ,for maintaining the equilibrium between vegetative growth and propagative growth and for good sunlight exposure, to fruit early to achieve high yield and to get commodity with high quality
2、the pruning methods are best determined by the characteristics of fruit species and cultivars ,the
climate the soil condition and the crop developing stages and growth status .in order to get the best result ,it is uful to combine pruning with other cultural practices like fertilization ,irrigation, etc 3、Reinvigoration of trees is better performed annually, which can keep fruit from stimulating excessive
sprouts .remove dead branches, sprouts and some crossing shoots. Secondly, large branches should be thinned out gradually to open tree chamber and to improve distribution of sunlight in order to
simulate fruiting.
Lesson15 part A
1、temperature is an critical element in biological ,chemical and physiological process of all plant
species
2、Temperature regulates the rate of chemical reactions ,leading to the adjustment of plant growth rate.
3、As a important contributing factor to climate .temperature play an important role in adaptability and
growth ,date of plant thus the horticultural crop types which can be cultured in a specific area rely on temperature
4、Most plants can live and grow in the range of 0 to 50℃ .however low-temperature nsitivity limit
the successful cultivated regions of plants
Lesson16 part A
1、sprinkler irrigation is often ud in maintaining and flower beds which has the specialty the uniform
water amount in its coverage .however, water waste occur when sprinkler is not limited in the area need irrigation .in addition ,evaporation result in some water loss too
