Last week we discussed how to grow vegetables in partial sun. This week we learn how to protect vegetables from too much sun.
上周，我们讨论了如何在局部的阳光下种植蔬菜。这周，我们将要学习如何避免植物过度受到光照。
Curtis Swift is an extension agent at Colorado State University. He says shading plants from intense sunlight in hot weather can increase production. Plants can suffer damage when their temperature rises above thirty-two degrees Celsius.
柯蒂斯·斯威夫特是科罗拉多州立大学的推广员，他表示在酷热的天气，遮蔽植物可以增加产量。温度超过32度时，有损植物生长。
CURTIS SWIFT: "Tomatoes, peppers, eggplants, and okra and other members of that family drop flower buds and young fruit when the plant temperatures exceed thirty-two degrees C."
斯威夫特：“西红柿、辣椒、茄子、秋葵以及这一科的其他植物在温度超过32摄氏度时，花蕾和幼果会掉落。”
Plants can get sunburn. Yellow spots may appear on their leaves and fruit. These areas can become thin and white as plant tissue is affected.
植物也会晒伤，叶子和果实上会出现黄色斑点。植物组织受影响后，这些部位会变得又白又薄。
Curtis Swift says shade can help correct these problems.
而遮盖植物可以避免这些问题。

He suggests shading plants with bed sheets, shade cloth or brush -- in other words, sticks and branches. Cut them about a meter long and stand them in the ground on the south and west sides of plants.
他建议用床单、遮阳布遮蔽植物。或者是用灌木丛，换句话说，也就是枝条。把枝条砍成一米长，插到植物南面和西面的土壤中。
