Make the hormone truth to investigate to plants: The standard of measurement is lacked and supervised to fall into awkwardly

Make the hormone truth to investigate to plants: The standard of measurement is lacked and supervised to fall into awkwardly
" explosion water-melon " " contraceptive cucumber " " accelerate the ripening banana " Continue " food additive " After the disturbance, the question great waves of food security recur, about " plant growth regulator " Right and wrong,become nearly one period that the public opinions pay close attention to focus.
In fact, as far back as sixty or seventy times of last century, our province has already applied plant growth regulator to the production of crops such as the grain, melon dish, perform meritorious deeds never to be obliterated in regulating the growth of crop, raising the crops output. But why be in today, plant hormone universally condemned instead? Hormone of plant is true " One hundred hurts and not has a profit " (used at the end of a question)? Lian Ri will come, the staff reporter deepens the field, visits agricultural expert, supervision department, attempt, reduce plant, grow true features to regulate hormone.
The cucumber and tomato and grape may all be used
Because this time " The hormone disturbance of the plant " The initial one " The troublemaker " It is " explosion water-melon " ,So, the reporter locks primary interview goal the water-melon.
Earth under the beginning of June the Jin Dynasty, it is no longer the world of the vegetable canopy. In the field, various crops are growing up strong and sturdy. But is influenced by climate, the melon one just enters to sit in the real estate water-melon in the Jin Dynasty at this moment, still blooming on most rice shoots, a few water-melons of result are only as big as apple too.
In give it is round to be that Chinese cabbage spray insecticide vegetable grower this year no several mu of water-melons will be planted too in the Mr. Lies. Though emphasize and has not used by oneself constantly " Water-melon expand pharmaceutical " ,But he admit frankly peripheral peasant useful hormone accelerate the ripening water-melon situation that expand really.
He tells reporters, probably have 100- 110 days in growth period of the water-melon, as the water-melon got four 2.5 kilograms of in weight one time ago long, gush out this kind of growth hormone to the side of the melon with outboard body with the sprayer. "A dozen, the water-melon grows fast. " Generally speaking, each water-melon can be 1 kilogram long much, and can go on the market ahead of time. It is often higher to advance the listing price, in this way the profit is larger. Mr. Li says, seldom hit and expand the water-melon of pharmaceutical, its time when is preserved is longer, and the water-melons that used and expanded pharmaceuticals to grow up in a large amount, once leave the melon seedling, must sell quickly, " can not sell within three days, inside may be rotten " .
In fact, not only the water-melon, the other vegetables of melon and fruit are but also using plants to grow and regulate hormone extensively. A fruit grower who plants grape claims, on the previous day listed on grape, many fruit growers can use water to dilute and expand pharmaceuticals too, dip in in expanding pharmaceutical fruit that hang at tree, the grape can grow rapidly, increase the weight.
The peasants of some places are in growth of the cucumber, tomato, hot pepper, these vegetables, will use plant, grow, regulate hormone, purpose have two, first, in order to accelerate the ripening, two, in order to increase production.
The cereal crops is being used too Can restrain the wheat and lodge
Under the playing up of the media, people generally think plant growth regulator except increase production for peasants, let trade company make a profit, to consumer being to " have, one hundred hurt and have one profit " (used after an attribute). In fact, this kind of statement is not totally correct either.
While interviewing, a peasant who plant wheat tells reporters, plant the area of the wheat in the south in our province, meet such a predicament once, bear middle and later periods in wheat, it is improper because receive climate factor or culture measure, lead to the fact the wheat lodges by a large scale, it is ripe to influence the wheat seriously, so that drop in production in a large amount.
Before 1980, the scientific research personnel at that time found, before the wheat seeded, grew and regulated hormone with the plant - -Cycocel dresses seed, the wheat that these all sorts of sons grew out, can inhibit the wheat from lodging, in order to increase the wheat output, ensure the market supply to make great merit.
In addition, plant growth regulator performs meritorious deeds never to be obliterated in the fruit tree grows. For example apple tree, pear tree, peach, in the course of growing, a lot of unnecessary branch that grow vigorous in growth instead, influence important growth and rate of bearing fruit of fruit branch, will increase work load of fruit grower like this. Spray and delay pharmaceuticals, can inhibit the development of this kind of branch, raise the output of the fruit tree.
Hormone of plant is a little malicious It is safe that science uses
So agricultural the intersection of university and crop study Guo, doctoral supervisor of discipline, it seems while being firm while being flat in Shanxi, the plant has no fault to regulate hormone to grow, it is the person who uses it by mistake, for this reason put off easily by a slight risk, it is a method not scientific.
Professor Guo claims, hormone of plant is divided into two kinds: One kind is hormone that itself contains in the body of plant, one is plant growth regulator of the artificial synthesis. In the 1920's or 1930's in the 20th century, the mankind found plants there is micro- natural plant hormone in the body, for instance ethylene, gibberellin,etc., have function of controlling growth. By the forties, began the research of the artificial synthesis analog, developed " 2, 4 - D " successively " it is red to restrain buds" Wait, popularize gradually.
