Vegetables are not afraid of insects in the "mosquito net".
Hainanese love to eat leafy vegetables, especially small vegetables. In recent days of continuous heavy rain, I can buy a green leafy vegetable for the public, and the joy is no less than a jackpot. However, it is difficult for the vegetable growers to keep the leaf vegetables in the rainy days. Some vegetable farmers in Haikou have adopted insect-proof nets to grow vegetables. They have only blocked the insects, but they have no intention of inserting willows. Under the protection of insect-proof nets, leafy vegetables are protected from wind and rain, and the sale is intact.
On the morning of August 14th, in the village of Qunshan Village, the vegetable production and marketing professional cooperative of the provincial pollution-free agricultural products association in Lingshan Town, Haikou City, there was a “mosquito net†over the vegetable field of the vegetable farmer Liang Fagao. Below the “mosquito netâ€, it was green and green. And spinach.
"These acres of leafy vegetables can be sold to the market in a few days, and the sales volume should be very good." Liang Fugao said.
These "mosquito nets" in the vegetable field, the scientific name is called the insect net, it is a layer of mesh film. Standing in the vegetable field of Liang Fagao, the Hainan Daily reporter saw that the stone pillars of more than 1 meter were neatly arranged in the vegetable field. The top of the stone pillar was placed with steel bars horizontally, and the steel bar was covered with a layer of insect nets with dense holes. It is both ventilated and protected from the sun. "It can also prevent rain in the rainy season." Liang Faga introduced.
In the torrential rains of the past few days, the leafy vegetables planted by many vegetable farmers in Haikou are not the leaves being smashed by the rain or the roots being soaked by the accumulated water, causing heavy losses. The leaves in the Liangfa highland are intact, and the "power" is the insect net.
"The rain hits the elastic mesh surface and will be bounced back into small droplets and slowly spread out, which reduces the impact of rain on the delicate leaves." Liang Faga explained.
There is no such thing. In the years of exploration and experiment, Cheng Fangfang, president of the Provincial Pollution-free Agricultural Products Association, summed up a cost-effective rain-proof method, which is also used to prevent rain. "The cost of this insect-proof net greenhouse is less than 10,000 yuan per mu. It can be used for two years. After that, you can change the mesh. The cost of the mesh is about 700 yuan."
At present, in the villages of Qunshan Village and Cangdong Village and Shapo Village of Chengxi Town, there are nearly 200 acres of vegetable plots used in such greenhouses, and the typhoon has also withstood the test of heavy rain.
“But the current use rate of insect-proof net greenhouses is still low, even if it is only sloping land, it accounts for less than 10%, mainly because the cost per acre is too much for ordinary growers.†Cheng Fangyu said.
