The fact that most of the new crops were of tropical or semi-tropical origin meant that in the Arab world they were summer, not winter, crops: sorghum, annual cotton, eggplants, watermelons and often rice are examples.

大多数作物起源于热带或亚热带这个事实表明在阿拉伯世界里它们是夏季作物，而不是冬季作物，例如高粱、一年生棉花、茄子、西瓜和大多的水稻。

The soil environment of solar greenhouse deteriorate with the growing ages increased and this causes the obstacle matters in soil of succession planting cucumber, mainly perform as soil physicochemical properties worsening, soil hypo-salinization, soil acidification. To solve these problems, corn and spring onion as catch crops were planted in summer after cucumber harvest that based on having no effect on cucumber production in solar greenhouse.. The experiment researched the effect of different catch crops on cucumber yield and soil physicochemical properties.

针对日光温室黄瓜生产中存在土壤理化性状劣化、土壤板结、盐渍化、酸化等土壤退化问题，在保证黄瓜产量的前提下，夏季休闲期选择玉米、大葱作为填闲作物，以农民传统的常规休闲作为参比对象，研究玉米、大葱对保护地土壤理化性状以及对黄瓜产量的影响。

According to the request of adopting advanced technology, the main designing has such contents as below:⑴ Designing the two-fluid nozzle that is based on the theory of air-atomize spraying.⑵ Designing and choosing the type of the axial fan that is used to supply assisted airflow to waft droplets that comes from nozzle.⑶ Designing the swaying outfit that can rotate the spray assembly at a speed and inside a angle in order to satisfy the spray request of different crops, different planting states and improve the uniformity of distribution, the deposition of droplet. Here, we select TYV type reduction gear motor to adjust the swaying speed and use course switch to adjust the swaying angle.⑷ Designing the lift outfit that can adjust the height of the spray assembly to satisfy the request of the crops of different tallness, different spraying range. Here, we select cylinder as the main component that can be used as kickstand and controlled easily.⑸ Designing the switch of the power supply that is put out of the greenhouse in order to prevent worker from poisoning. After the mist sprayer being made, the experiment is made to test the function of the greenhouse mist sprayer fully.
