Climate control cannot be seen as separate from the crop, for which one tries to create optimal conditions. Crop condition concerns a complex of properties which determinate the capacity of the crop to deliver good production over an extended period.

2.plasticulture
【n.】using plastic materials in agricultural applications.
3. polyethylene
【n.】 [化]
聚乙烯
A polymerized ethylene resin, used especially for containers, kitchenware and tubing, or in form of films and sheets for packaging.
塑料覆盖栽培也被称作第二次绿色革命，因为它已经 使世界范围内几乎所有的国家都显著提高了其粮食产 量。 As the Green Revolution expanded the production of agronomic crops, Plasticulture has provided yet another revolution. While more silent, plasticulture has enabled countries throughout the world to greatly extend their food production capability.
设施园艺作物栽培中，生产者对于环境管理的重点是根据作物的 特性和作物对环境的要求，尽可能创造出作物生育所需的最佳综 合环境条件。
In greenhouse culture, the key of environment management for productors is creating the optimum comprehensive environment base on crop properties and environmental demands as far as possible.
Natural mulches such as leaves, straw, sawdust, peat moss and compost have been used for centuries to control weeds and hold moisture in the soil. More over, plastic mulches also raise soil temperature and increase soil nutrient supplying. Today, as in 1959, Japan uses mostly polyvinylchloride (PVC) film for row covers. In other countries, polyethylene predominates.

As the Green Revolution expanded the production of agronomic crops, plasticulture has provided yet another revolution. While more silent, plasticulture has enabled countries throughout the world to greatly extend their food prodiction capability. It is only in the last fifty years that synthetic materials have altered the methods and benefits of mulching.


One example of quality improvement through climate control is the recently developed concept of DIF temperature.
气候控制不能看成是与作物相隔离的，因为温室气 候控制就是要试图创造作物理想的生长条件。 Climate control cannot be seen as separate from the crop, for which one tries to create optimal conditions.

The use of climate control can influence the most important above-ground growth factors. These factors are light, CO2 concentration, temperature and air humidity. As a result of evaporation, photosynthesis and respiration, the crop influences the mass balance of CO2 and water vapor pressure of the air, as well as the energy balance.
“作物状况”关系在较长一段时期内作物体内物质生 产和同化产物运输能力的综合特性。
Crop condition concerns a complex of properties which determinate the capacity of the crop to deliver good production over an extended period.
Lesson 1 Early Development and Status of Plasticulture
1.green Revolution
【n.】
绿色革命
A significant increase in agricutural productivity resulting from the introduction of high-yield varieties of grains, the use of pesticides, and improved management techniques.
塑料不仅可用于温室透明覆盖，也可以取代无土栽培 种植床的水泥硬化地面，或做成塑料袋填装无土基质， 进行无土栽培生产。 Plastics not only can be used as glazing cover of greenhouse, can also in place of the concrete in lining the growing beds , or be made to be plastic bag for packing growing media to soilless culture.
