Two tricks to prevent and cure
In recent years, aphid pests have occurred in large numbers throughout the country. After autumn crops are harvested, they are often transferred to vegetable fields to injure cabbage, radish, carrots, spinach and other late autumn vegetables. Its prevention and control methods are:
To poison bait, firstly dissolve 90% crystal trichlorfon into 30 times liquid with warm water of 60°C to 70°C, take 1 kg of liquid, and spray evenly on 30-50 kg sauteed wheat bran or cake flour (mixed When you want to fully add water, usually 1 to 1.5 times the weight of the bait, mix well and spread it in the vegetable field, 3 to 5 kilograms per mu, the effect is good.
The grass trapping uses the habit of grasshoppers plucked under the thin layer of haystacks. The small haystacks with a thickness of 10-20 cm are evenly placed on the field in rows of 5 meters and 3 meters long. The grass will be collected and killed the next day; Putting some poison baits under the haystack or using a wooden stick with a diameter of 3 to 5 centimeters will make it better. This method is not convenient for large-scale promotion, but it is suitable for application in vegetable fields.
Colorful Mottled Waxy Corn is generally white, yellow, red, purple and black, with white, yellow and Black Waxy Corn being the basic colours. The purple gene of a purple-white cross naturally becomes purple if it "beats" the white gene, and vice versa, so if the two make a tie, we see white and purple corn. Purple can turn into red and Fresh Black Corn, or as we often say, "red is purple and black is purple". Of these Mottled Waxy Corn, the most common Yellow Waxy Corn is the most nutritious, as it is rich in carotenoids.
