how to identify contaminated vegetables
1, full of vegetables with warm water to soak for 20 minutes,
supra shoes discount, and thoroughly washed 3 times.
crops affected by chemical pollution is divided into two categories: class used hormone auxin; fertilizer or soil in the possession of toxic components. Studies have shown that by chemical or toxic ingredients in the contaminated soil, the crops will be deformed.
3, curly leaves, like lettuce and other vegetables, should wash the leaves fully flat.
March of this year, the old He bought a handful of melon seedlings ganchang. Guayang Zaijin vegetable, the remaining one no place to species. He could not bear to throw the old, planted in Yuanba before it had grapes in the dirt pile.
pollution, experts recommend not to eat
the three major causes of conjecture】 【
how old the Experts say the best time to uncover the truth has been missed. Outstanding achievements in the pedicle, the understanding of flower pollination, the fruit forming process can be understood. But once the end of Results pedicle results pollination, pollination, whether there are other fruits and pollen cross, it is not known.
4, can be peeled and eaten as vegetables peeled.
. Showing the envy of every other people, and surprised eyes, how old is happy like a child, take the initiative to explain the origins of Guayang.
2, with Taomi Shui vegetables,
jordan 10, can reduce pesticide residues on vegetables. However, the first one or two Taomi Shui is best to use,
adidas zx 700 68岁白叟考上中心美院 成该校年纪最大, because the surface of rice potassium, the first two Taomi Shui of a weak acid,
cheap shoes website, then converted to alkaline - acidic pesticides only in the loss of certain toxic substances will .
when other Guayang Garland, flowering, fruiting, the kinds of soil where the grapes are quite different Guayang - Guayang wrap the vine after vine, vine leaves kept soaring, Results out of the
melon is very thick, thin and long if the melon is the case, the only reasonable explanation is that plant genetic gene variation. Probability of occurrence of the mutation is small, but can not be ruled out.

College of Horticulture, Landscape Architecture, Southwest University experts said Mr. Song Ming, strange,
3, see season. Eight more vegetables and pesticides applied, should be careful to buy. May to October, is the largest seasonal vegetables of pesticides applied. At this point, more vegetables with pesticide eggplant, beans, cabbage, cauliflower, bamboo dishes, chili, cucumber, cabbage. May to October, with pesticides in food are less pumpkin, zucchini, garland chrysanthemum,

change of position long good time
stop growing, when fruition if he was prepared to
melon, and he do not know.
1, see the individual. Where individuals or deformity unusually large tomato, pumpkin, melon and other fruits and vegetables, may have used growth hormone, it is best not to buy. Observation is to see people often say
south area Guang Yang Zhen Yuan Ba, a new six villages, a 73-year-old villager He Guorong thing so mixed: a melon seedlings bear a Peel, has always maintained about 20 cm in diameter, look like a wooden club.
2, see shapes and colors. Such as special large leek leaf hypertrophy,

michael jordan shoes, but also than the average width of a leek leaf width times, the process may be used in the cultivation of hormones. Vegetables such as cabbage leaves, abnormal leaf color, green will be presented the usual dark green; soybeans and other beans, may also be used if the green abnormal hormone.
hi, the The worry is that,
market, some grow unusually long or large eggplant or loofah , claims to be breeding in space. Unfortunately, the so-called space breeding business selling mostly a gimmick, even if the space is really melon breeding, farmer bought a handful of Guayang, only one went to space, which is too outrageous.
