have a lot of people think, and now so many out-of-season fruit, and fruit has become a greater and more beautiful than ever, I am afraid this is the use of illegal farmers "plant hormones" result. These fruits look beautiful, to eat up there is a lack of aroma, and not enough sweet. Their low nutritional value, should not reach the normal products. Some people even question the use of plant hormones in fruit, are not now a lot of kids mature earlier one of the reasons for it?
heard about such problems, one can not help some sad. It should be consumer demand for their own reflection, but now have shifted to the duty-of-season fruit and body, to the peasant who, it is not fair.
To answer this question, but also from the place talking about the most fundamental: What is a plant hormone, why should deal with these substances fruit.
plants and animals, and their life activities, has a number of chemical substances required to regulate and control. Research has already found that there are five major types of natural plant hormone, auxin, respectively, are categories, gibberellin, cytokinin, abscisic acid and ethylene. Proportion of their different growth and development will bring about change. For example, auxin promote long roots, stems and leaves of gibberellin to promote long, cytokinin to promote the occurrence of bud and fruit development, ABA promotion of aging and stress resistance, ethylene to promote ripening. These hormones are a natural material, exist in any of the plants. Simulation of these hormones and their chemical substances, have long been used in agricultural production which. For example, using growth hormone to promote root development category, allowing transplanting of fruit seedlings survived more easily; by gibberellin treatment, you can not let the fruit seeds; be able to release if ethephon to ethylene treatment, allowing the Green yellowing ripe bananas this ...... these are the normal operation of agriculture, the world is true.
currently used plant hormone substances or "plant growth regulators" are approved for use in formal National Product, and its toxicity and residue are consistent with the requirements. Under the guidance of agronomist at the use of these products, not "wrongful." These things can contribute to fruit development, and that they should not become the reason for harmful. In fact, the growth of active substances because of these very sensitive role, farmers can not be over-use, because the use of a slight increase, it will bring the production on the adverse effects of barriers such as plant growth, or abnormal fruit growth.
However, people often feel that the quality of fruit is now not so satisfactory. Some fruits, great head, but the flavor is not good, people suspected to be the use of the "swelling agent." Some of the fruit looks very pretty, but does not taste sweet, it is suspected to be the use of the "ripening agent." In fact, such a situation arise, and should not blame the farmers, the consumers can only blame themselves.
first talk about ripening agent. It is well known that after the ripe fruit will soften, 23 days on a broken, but will rot away after the bump, it is difficult to store and transport. From a distance in order to put a large number of fruit shipped from, is bound to seven at the time ripe for picking. To the sale of places, in order to be able to sell, but also it can be consumed to achieve the status, it is necessary, such as the use of ethephon ripening. This is in order to meet the long-distance transport and storage is bound to take necessary measures to be able to blame the farmers吗? Who let the town people of non-eat-season fruits, non-eating distant fruit? Natural eating only fully ripe fruit aroma and taste, but went to Hainan Island go bananas and mangoes, for the vast majority of people, it is very difficult to do. However, put the cooked bananas and mangoes shipped to Beijing, who have the ability to do this? Yunlai blue banana, if it is not ripening agent, is said to eat bananas directly吗?
now that we need to violate the laws of nature, autumn winter to eat the fruit, now that want to enjoy the fruits other than 2000 kilometers, it is not to dream and to be quarter of the local quality is as good as anything. This is not the fault of farmers, nor are ripening agent mistake, consumers should be able to understand.
repeat expansion Say agents, it is merely brought up the promotion of fruit growth regulator, but have grown up over the decline in quality will inevitably bring about. I know some examples, some farmers do not want to use the growth regulator, they think these things is very expensive, will increase the cost of the product. But no way, if they do not, the fruit vendors on the price they are unwilling to make good use of the fruit, because fruit size is not big enough. Finally, those "conservative" farmers will be very tragic, and finally had to take the "advanced" technology. Similarly, if they do not want to find ways to help fruit color pretty enough, consumers will not be willing to buy, then the farmers can only lose.
U.S. farmers is poor. They use a variety of pesticides or growth regulators are all in order to defend the fruits of their labor, or those who can accept the purchase. They are not intentionally harmed others, and those who sell agricultural businessmen Farmer pharmaceutical, often want a very high price. Some people say that why the peasant to eat their own sophisticated natural products, pesticides and chemical fertilizers, do not eat the product? That is because they themselves engaged in production and have to eat ripe fruit of natural conditions, and they do not like the city people demanding the appearance of color quality, they know what kind of fruit is really good fruit!
