How many days can I eat a green leafy medicine cucumber?

It is not recommended to eat it again.

Cucumbers prefer to be warm, and the suitable temperature for growing is between 25 and 32. It can be watered appropriately during the growing period, every three days and every seven days during flowering. There is not much requirement for light, it is enough to receive light normally, and it can grow normally in full sunlight.

Sufficient basal fertilizer needs to be applied before planting, and top dressing needs to be continued several times during the growth period.

First, the maintenance method.

1. Temperature: cucumbers like a warm growth environment, the normal growth temperature is between 20 degrees and 32 degrees, low temperature can not be lower than 15 degrees, to avoid frostbite, high temperature should also be noted, try not to exceed 35 degrees, otherwise it is easy to be burned branches and leaves, so cucumbers will also be dehydrated, so winter breeding needs to be in the greenhouse.

2. Watering: cucumbers during the growth period need enough water, which can promote the growth and development of seedlings, watering almost every three days, and not watering more during flowering, to prevent excessive watering and frequent flowering of plants, so try to wait until the ground is all dry before watering, almost once every seven days.

3. Light: Cucumber does not have too high requirements for light, but it cannot stay in a dark environment all the time, it can accept full sunshine. There is no specific standard for a few hours of light every day, and strong light can be avoided in summer, and the gherkins that have just grown in the heart can be dried and wilted.

4. Fertilization: Before planting, it is necessary to apply sufficient base fertilizer, which can help the growth of seedlings, and at the same time can be topdressed many times during the growth period, mainly based on water-soluble fertilizer for fertile leaves, of course, animal manure is also available, which can improve the yield, increase the immunity of plants, and reduce the occurrence of some pests and diseases.

Second, breeding skills.

1. Reproduction: sowing is the main way of reproduction, can be planted in a large area, sowing can be carried out in the spring, the temperature at this time is also just right, after sowing to water thoroughly. Then, in order to prevent water loss, you can cover it with a layer of plastic wrap and press it gently afterwards to help the seeds grow.

2. Pruning: During the growth period of cucumbers, the branches and leaves may gradually age, and they can be cut off directly, because the aging branches and leaves do not have any effect, in order to prevent the loss of nutrients, they can be cut.

Sprayed green pages to prevent scratches, it is best to eat it after a week, and wait for the effect to decompose before you can do it.

Cucumbers may turn yellow soon after they grow for several reasons:

Lack of light causes the leaves to not fully synthesize chlorophyll, resulting in yellowing. Celery is pure and resistant.

Watering too much or too little can lead to a lack of oxygen or water in the root system, affecting nutrient uptake, resulting in yellowing.

Improper fertilization leads to an imbalance in soil pH, which affects nutrient absorption and thus turns yellow.

Pests and diseases, such as downy mildew, gray mold, powdery mildew, viral diseases, root-knot nematodes, whiteflies, etc., cause damage to the leaves or loss of nutrients, resulting in yellowing.

What pesticides can be used to solve the problem depends on the specific cause. In general, the following measures can be taken:

Adjust the light conditions to ensure that the cucumbers have 6-8 hours of sufficient sunlight every day.

Adjust the frequency and amount of watering to keep the soil moist but not too wet to avoid standing water and drought. Disgusted spring.

Adjust the method and amount of fertilization, maintain moderate soil fertility, and avoid over-fertilization and lack of fertilizer. Organic fertilizer or compound fertilizer can be used as the main fertilizer, and trace elements such as nitrogen, phosphorus, and potassium can be appropriately applied.

To control pests and diseases, choose the corresponding pesticide spraying according to different pests and diseases. For example:

Downy mildew: It can be sprayed with 500 times of 75% chlorothalonil wettable powder or 500 times of 58% methyl frost and manganese-zinc wettable powder.

Botrytis cinerea: 50% promethein wettable powder 1500 times liquid spray or Cerax wettable powder 600 times liquid spray can be used for pants.

Powdery mildew: 20% tetrafluorine can be used. Pyrazole ester or 15% powder rust 1000 times liquid spray.

Viral disease: can be sprayed with 20% Virus Buster 500 times liquid or 20% Virus A500 solution.

Bacterial angular spot disease: can be sprayed with 5000 times of neophytomycin or 500 times of 30% copper succinate (DT fungicidal) wettable powder.

Root-knot nematodes: Insect mite gram emulsifiable concentrate per square meter can be mixed with 6 liters of water to disinfect the soil or sprinkled with 4-6 kg of Millel 3% granules per mu.

White whitefly: can be sprayed with 10% imidaxcarb 400-600 times liquid or 10% parametrix emulsifiable concentrate 1000 times.

OK. When using insecticides to spray cucumber seedlings and other plants, the meteorological timing is very important, it is necessary to avoid high temperature, rain and snow, strong winds, etc., and it is best to choose the timing of stable airflow and suitable temperature, which can not only ensure good insecticidal effect, but also avoid plant damage, and also benefit the health of operators.

Therefore, it is a good choice to apply pesticides to cucumber leaves on cloudy days.
