Field tube technology for vegetable production after rain
Sustained rainy weather caused a certain impact on the growth and development of vegetables. When the weather is fine, anaerobic respiration occurs due to a long period of time when the roots are flooded, causing the plants to lose water, wilt, and even die. In order to minimize losses, the following remedial measures are proposed: Fresh Single Packed Mottled Waxy Corn
Waxy corn is generally in the majority of Yellow/Purple/Mottled, which is relatively high in protein content, rich in vitamin A, vitamin B1 and other nutrients.Waxy corn starch content up to 70%~75%, that almost is amylopectin.Amylopectin makes waxy corn more chewy.But, it's high in polysaccharide, so diabetics better eat less.
Mottled corn when you buy corn in the market, you may see some multi-color corn, is mottled corn. There may be some friends think colored corn is genetically modified or dyed, in fact, mottled corn is actually a natural hybrid formed, its nutritional value is extremely rich. Mottled Corn Kernels are full and shiny. They don't taste as sweet as sweet corn, but they have a special aromatic taste that makes them taste just as good as regular corn.

First, the drainage of the ditch, repairing the shed film to open the three ditch in good time, keeping the ditch open, so that no water accumulates in the shed, and can use the pump to drain water on some low-lying, slow-moving plots in time to ensure that there is no product in the plot. water. The damaged part of the film should be promptly repaired to ensure the normal production of Qiuyan cuisine.
Second, timely supplement of fat seedlings due to waterlogging affected by the serious loss of fertilizer in the field, coupled with the roots of vegetable growth after flooding decreased vitality, poor ability to absorb fertilizer and water, to seize the opportunity of timely recovery after the sunny rain. The first is to take up the soil. For different plots, it is necessary to flexibly determine the amount of fertilizer to be applied, and the fields affected by severe crops, serious fertilizer loss, and large seedlings should be properly supplemented, and the crops that are lighter, have less fertilizer and water loss, and have smaller seedlings should be lighter. Make up. Generally, about 5-10 kilograms of urea can be applied per acre, and 10-15 kilograms of superphosphate can be mixed. Leaf vegetables are dominated by nitrogen fertilizers, and they are less frequently used; they are used in combination with nitrogen, phosphorus, and potassium fertilizers for melons, solanaceous vegetables, and legumes. The second is to adopt foliar spray fertilizer to prevent premature aging of crops. Mu with 0.3-0.5% potassium dihydrogen phosphate and 1% urea mixed solution, foliar spray, timely nutrition, promote growth and development, spraying once every 7-10 days, generally even spray 2-3 times.
Third, timely prevention and control of pests and weeds Continuous rainy weather is very conducive to a major outbreak of diseases, solanaceous vegetables, legumes and vegetables in the rainy season or good weather, spray one to two sterilization, multi-bacterial The fungicide such as thiophene and thiophanate-methyl can prevent bacteria from invading from the wound; if insecticides are found, insecticides should be sprayed, but the use of 5 pesticides such as methamidophos is strictly prohibited; to keep the garden clean, weeds and diseased plants should be removed.
IV. Replanting and replanting as early as possible Some crops with severe or severe disasters will be seized and favorable opportunities will be seized. Market gaps will be seized, and a batch of Chinese cabbage, leeks, spinach, and quail with a long growing period will be broadcast live. Fresh vegetables such as spinach spine and edible fungus, or replanting cabbage and radish with a growth period of about 60 days, can both enrich the market supply and increase the income of vegetable farmers; they can sow autumn cabbage and autumn radishes when they are looted in old vegetable production areas. Cucumber, beans, celery and other high-yield and high-efficiency crops. There are three points to be made when making changes: First, early sowing, the sooner the better, the full planting, and the autumn supplement; the second is the increase of density to cover the night; the third is to select the short growth period. , Do a good job of cohesion, prevent the impact of the squat.
