Can small arched beans be watered When are the long beans watered in the greenhouse

1. Small arched beans can be watered.

2. Watering to keep the soil moist can promote the growth of beans.

3. Don't water too much, so as not to hurt the roots.

Beans should not be fertilized more in the early stage, to prevent too much fertilizer and water, cause growth, affect flowering and poding, after surviving watering 1 time of decaying manure, when the plant flowers and podding, generally top dressing 2 3 times, 5 15kg of urea per 667 square meters, or 750 1000kg of manure and urine of rotting acquaintances, to promote plant growth, more flowering, more pods. During the peak harvest period of the pods, fertilizer and water should be increased, and if there is a lack of fertilizer and water at this time, the flowers and pods will fall, and the growth of stems and vines will decline. After topping, the flowers can also be turned over to extend the harvest period.

After the vine is drawn, it is necessary to set up the frame in time, and the vine should be drawn in time after the frame is erected, and the vine should be carried out in the afternoon on a sunny day, not in the rainy day or in the morning, in case it breaks. Reasonable pruning, so that the stems and vines are evenly distributed, and the utilization rate of light energy is improved. The main vine and side vine pod-setting were used to increase the number of inflorescences and their podding rate, prolong the harvest period and increase the yield.

To this end, the side vines should be selected appropriately, the side vines with weak growth and late occurrence of the first inflorescence should be removed, and the side vines with strong growth and early occurrence of the first inflorescence should be selected, among which the side vines that grow above the middle of the main vine should be left with 4 5 leaves after the first inflorescence is extracted to increase the number of inflorescences and promote the good development of inflorescences; The main vine grows to the top of the scaffolding, and the vine can also be topped when it is about 2m long; Promotes the formation of secondary flower buds on each inflorescence and facilitates the harvesting of pods.

When beans bloom, do they need to be watered? Today we are going to talk about whether it can be watered or not.

Summary. Hello, dear! Yes. But watering is not very good at this time. One is to reduce the temperature, which is not suitable for the growth of beans, and the other is to increase the humidity, which is easy to cause diseases.

Hello, dear! Yes. But at this time watering is not as good as space lead. One is to reduce the loss and eliminate the low temperature posture, which is not suitable for the growth of beans, and the other is to increase the humidity, which is easy to cause diseases.

Okay in the afternoon. Watering of greenhouse beans on cloudy days, less or no watering. Because the greenhouse is cloudy, it may rain, and the soil in the shed is moist.

Spring bean carob greenhouse to promote cultivation is generally sown in the first half of March, germination sowing, live broadcast can be, plant row spacing of 20 cm 40 cm, each hole sowing seeds 3 4 grains, seeds sown covered with mulch, and covered with greenhouse film insulation, until the emergence of seedlings. Water management at the seedling stage is based on the principle of control. After the seedbed is watered, it can no longer be watered; Nutrient bowl seedlings can be watered appropriately when the soil is dry.

In particular, do not water for 7 days and 10 days before planting to make the seedlings robust and sophisticated. The seedling age in early spring is generally 25 days to 30 days, and the standard for strong seedlings is that the primary leaves and true leaves are large, dark green, and the internodes and petioles are short. At noon on a sunny day when planting, the ditch is first opened to irrigate the wax, and the seedlings are planted after the water seeps into the mountain; Or open a ditch to plant seedlings and then irrigate.

No matter which planting method, the amount of irrigation should not be too large, and the wet soil mound shall prevail, so as not to reduce the ground temperature, and cover it with dry soil after planting. The distance between the holes is 40 cm and 50 cm, and the vines are hung with plastic ropes.

It is recommended that you do not water too early, and you can choose the afternoon time slot.

Hello, dear, I'm glad to answer for you that you need to water once after guessing the crack planting beans, watering at the seedling stage is generally watering when the soil surface is dry, about 3-5 days to water once. However, the maintenance environment is different, and the water evaporation rate is also different, and the specific watering frequency must be reasonably adjusted. It should not be watered frequently, and the soil should not be too wet, otherwise the seedlings will grow easily, or the seedlings will drown.

During the fruiting period, watering is usually carried out weekly.

1. Seedling raising, most of the previous production of beans using live broadcasting, in recent years, greenhouse production is in the late winter and early spring, the temperature is low, due to the cold resistance of the beans is relatively weak, the selection of seedling transplanting method is more appropriate, on the basis of fully protecting the root system from cold damage to ensure that the seedlings are strong; Generally, it is sown from late November to early to mid-December, and the seedlings are raised in a nutrient way or a nutrient bowl, and a small arch shed is added to protect against cold and moisture after sowing. Reasonable control of temperature, both to avoid the seedling stage"Red root"phenomenon, and to prevent it from growing. The seedling age is about 23 days.

2. Post-planting management. 5-7 days before planting to cool the seedlings, night temperature 8, 15-18 during the day, ground temperature 11, when the seedlings grow to two leaves and one heart, the calendar seedling age reaches about 35 days can be planted. The whole seedling period is not watered and not top dressing, so it must be watered with water on the bottom of the foot, if the seedling leaves are yellow, you can use the left and right potassium dihydrogen phosphate solution or urea solution for foliar spray.

In mid-January, the beans began to stretch the vines, at this time began to chase the pod fertilizer, about 50 kg of cake fertilizer per mu, you can also chase the thin manure, you should also water the pod water, can not water too much, and then insert the frame, because the growth of the bean seedlings is in a low temperature, weak light environment, photosynthesis is hindered, and the nutrition of the plant itself is limited, so it must not be too dense when planting, in order to prevent the leaves from blocking each other. Generally, 70 cm and 50 cm ridges are planted, the plant spacing is about 30 cm, watered after planting, and then hoeed and then covered with full mulch.

3. Field management during the peak pod-setting period. In addition to absorbing a large amount of phosphorus and potassium fertilizer, an appropriate amount of nitrogen fertilizer is also needed, strengthening covering, heat preservation, strengthening lighting, and often wiping the shed film to make it transmit well. The first draft is like the secondary topdressing with the proportion of pure nitrogen, phosphorus pentoxide and potassium oxide content is 24:

At 11:40, properly ventilate 2 hours after application, chase 1 fertilizer and water 1 time for every harvest after clearing. By the end of April and the beginning of May is the peak period of the transfer of beans from the main vine pods, at this time has entered the stage of high temperature and high humidity, due to the aggravation of diseases and pests, the fall of flowers and pods is serious, the growth of beans in the later stage of plant senescence is fast, the root system is aging, in order to prolong the pods, the potassium dihydrogen phosphate can be sprayed for foliar fertilization.

After the beans are stretched out, they should be set up in time to lead the vines, and they should be beaten and smeared in time, so as to avoid blocking the sunlight between the leaves as much as possible, and pluck the tops in time when the plant is tall to promote pods.

Pumping period management:

Soybean seedlings have vines extracted, to carry out large soil, combined with fertilization, 30 kg of phosphate fertilizer plus 10 kg of urea per mu, evenly applied on both sides of the ridge, with furrow soil will be fertilizer and weeds covered, pay attention to fertilizer and soil do not touch bean stem.

If possible, 2000 kg of manure can be applied per mu and soil can be cultivated on the edge of the ridge.

After cultivating the soil, it is drenched with thiamine mixture, and 1 kg of copper sulfate and 2 kg of carbon amine are added to 1000 kg of water per mu.

Introduction to beans: Vigna unguiculata, also known as cowpeas, is a vegetable that is abundant in summer. It is a cultivated species that can form elongated pods in cowpea species, and is an annual winding herbaceous plant.

Also known as carob, carob, bean, wakabean. Contains various vitamins and minerals, etc. The flesh of the tender bean pods is thick, crisp and tender when fried, and it can also be scalded and then served cold or marinated.

The pods are long and tube-like, brittle and soft, and are commonly found in white beans, green beans, and purple beans. When buying beans, it is generally better to have uniform thickness of bean strips, bright color, transparent and shiny, and full grains, while beans with cracks, wrinkled skin, too thin and no seeds, and insect marks on the epidermis are not suitable for buying. Beans have a good nutritional content and are the meat among vegetables.

Yes, at this time, you should use compound fertilizer with slightly higher phosphate content.

The three major elements needed by plants, nitrogen (N), phosphorus (P), potassium (K), potassium fertilizer is to make fruits, rhizomes, swell, stout, peel coloring, easy to bear fruit, phosphate fertilizer is to make plants bloom more, sprout more, promote flower bud differentiation, nitrogen fertilizer is to make the leaves dark green, that is, long leaves.

Fertilization must remember to apply thin fertilizer frequently, a single amount is not too much, but you can apply it several times, generally once every 10 days or so, and keep the soil moist after application

The judgment of watering after the bean seedlings are unearthed is mainly based on whether the soil is short of water:

1) If the soil is very dry, then you can water it immediately, a small amount is enough;

2) If the soil is moist and there is no shortage of water, you can wait until two leaves have been left before watering.
