Eight points of summer and autumn pepper breeding
In the late summer and early fall, the temperature is high, and the light brings a certain degree of difficulty to the nursery. The vegetable farmers' friends pay attention to the operation procedures, do the nursery skill, manage the science, and take the following measures to ensure that the pepper grows.
Seed treatment: After selecting good varieties, the seeds are first dried for 4 hours, then disinfected by trisodium phosphate solution, and then soaked in fresh water for about 8 hours. Let cool after removing and prepare for germination.
Germination at room temperature: Now the room temperature is usually around 30°C, which is the suitable temperature for germination. Soak the soaked seeds in cotton cloth and moisten with a plastic film. The seeds are flushed with clear water every half-day, and then germinated again for about 60-70 hours. The seed is best when the shoot length is about 3 mm; if it cannot be sown in time, the seed should be kept under the condition of about 8°C, and the seeding conditions should be created as soon as possible.
Preparation of plug tray: Use special nursery medium, vegetable farmers friends can according to their needs, calculate the number of nursery plugs and nursery medium required. The nursery medium is mixed with an appropriate amount of phosphorus and potassium compound fertilizer, special biological micro-fertilizer and other trace elements, etc. After mixing with water, the plug tray is leveled and sowed.
Preventing high temperatures: After sowing, the plug tray is irrigated and sprayed with Prok then covered with plastic film. At this time, we should pay attention to shade and cool down, prevent steamed seeds from affecting sprouting. At this time, the temperature should be controlled below 30°C during the day and below 18°C ​​during the night. When the emergence is about 80%, the plastic film can be peeled off. With the growth of the seedlings, the time for covering the shade net can be shortened, which is more conducive to the growth of seedlings.
Prevent drought: After sowing seedlings, always pay attention to the humidity of the seedbed, do not get too wet or too dry. Many vegetable farmers are afraid that the seedlings will be too long and they will control the watering and cause the plugs to be overly arid. At this time, the capillary roots are damaged due to water loss and drought, affecting the absorption afterwards. The ability to form weak seedlings is susceptible to illness. Therefore, it is advisable to water it properly when it is watering.
Prevention of seedlings and apprentices: The main reason for summer pepper seedlings is mainly because of the high night temperature, strong respiration, and excessive nutrient consumption. Then, nitrogen fertilizer and moisture are sufficient to cause seedlings to become leggy. In addition, the seedlings shaded each other too much and affected the photosynthesis. Therefore, the prevention of seedlings should pay attention to the prevention of excessive night temperature, plug wet too much; and then apply less nitrogen fertilizer; the third is when the seedling grow to a certain size, the inter-pull spacing to increase ventilation Transmit light, strengthen photosynthesis to avoid seedlings growers.
Prevention of rainstorm damage: If the seedbed is set in a shed, usually a membrane or two-mesh cover method is used. When there is heavy rain, the shed film can be pulled down and buried well to prevent the rain from showering on the seedlings and the rain-borne germs.
Prevention of pests and diseases: At this stage, because the external environment is more conducive to the occurrence of pests, pest control should also be strengthened. For example, in the nursery shed, set up a tight insect net; use the tendency of pests to set up the yellow plate to induce trapping whiteflies, and use blue plates to trap and kill the thrips; if necessary, use chemical control.
The variety of beans, rich in nutrition, often eat beans are good for the body. Can reduce adipose content, increase immunity, reduce the chance of getting ill.
Red bean can be heart, diuresis, alcohol, detoxification, heart disease, kidney disease, edema has a certain effect. Red bean also has more dietary fiber, have good
The functions of nourishing bowel to relieve bowel movements, lowering blood pressure, lowering blood lipids, regulating blood sugar, anticancer and losing weight.
Mung bean tastes sweet and cool, has the function of clearing heat and detoxifying, can help human body excrete toxin, can reduce cholesterol, protect liver, fight allergy.
Soy can fill the spleen, promote metabolism, diarrhea, abdominal distension and other symptoms of supplementary food therapy, hypertension, coronary heart disease, arteriosclerosis, obesity, diabetes and other patients, but also help delay aging.
White kidney bean contains saponins and various globulin, which can improve human immunity and prevent respiratory diseases. Black beans can promote kidney to eliminate toxins, a strong kidney nourishing kidney, activating blood and moisturizing effect.
Beans contain a lot of phytic acid, which will affect the absorption of trace elements such as iron and zinc. The phytic acid content of bean sprouts made from beans will be greatly reduced, and the utilization rate of iron, zinc and calcium can be greatly improved, so that the five zang get better tonic.
