When the temperature is low, what should I pay attention to when planting strawberries?

The temperature is getting lower and lower, and the growth of strawberries has entered a new period-flowering period is also a key period to determine the yield and benefit. Many friends don't know how to manage this time, which often comes from misunderstanding. Today we will look at the actual production and how to get rid of these misunderstandings. Please criticize if you have anything. It's getting colder and colder. How to avoid strawberry management from one misunderstanding to another?

First of all, it's better for Pelica.

The more potassium, the more strawberry fruits? In fact, although strawberry needs phosphorus and potassium fertilizer, nitrogen fertilizer is as important as other trace elements. Too much potassium can easily lead to too thin stalk and premature, too long and too fast fruit. Reduce output and quality.

Strawberry is a continuous flowering crop. Some fruits belong to the genus, some are young fruits, and some people have just blossomed, even in flower shops. Therefore, when applying fertilizer, the characteristics of strawberry in different fertilizer demand periods and fertilizer demand should be considered. Even the amount of potassium fertilizer used in flowers does not exceed 32.

In addition, calcium and potassium will have antagonistic effects. Therefore, the long-term fruit and fruit expansion need to start adding calcium-magnesium pig fertilizer to the leaves, which can improve the absorption efficiency of calcium fertilizer, increase the sweetness of strawberries, improve the hardness of fruits and improve the anti-adhesion of strawberries.

Secondly, in order to prevent diseases, there are more and more insects.

Will flow out, but because of the large-scale shed movies, the microclimate in the shed has changed a lot, especially the increase of humidity, which also provides conditions for diseases. We are good friends of raspberry. In order to ensure the prevention and treatment of diseases, we often enter this misunderstanding, increasing the dosage of drugs or reducing the interval between drugs, which is considered to be an immediate effect, but we are often willing to infringe drugs.

Prevention, comprehensive prevention strategies should be adopted in the process of pest control, because we have thorough prevention in plastic film and greenhouse, and pests are harmful to greenhouse. At present, strawberries are gradually entering the flowering period, especially in flowers, and it is possible to spray drugs on the leaves. At this time, drugs will cause many abnormalities, which will affect pollinated bees, so we must take precautions.

After covering the big shuttle film, many diseases are related to humidity, such as gray mold and white powder. This product can reduce the chance of blood damage, especially humidity, and reduce the chance of illness.

If there is a local pest in the shed, we can use watering to prevent it and find it at any time. If necessary, we can remove individual plants to remove the opening of the shed. If there are diseases and insect pests in flowers, smokers with rotten thyroid and sulfur smell can be used. It's getting colder and colder. How to avoid strawberry management from one misunderstanding to another?

Third, there are too many accounts receivable.

A year later, strawberries just came into the market. At first, the price was so high. How can you shake hands when you see strawberry flowers and small fruits in the shed? This is a shortcoming, and you must be full of contradictions. In fact, strawberry flower is a quaternion with four or more branches, the first level is the largest, the second level is the largest, and the third level is the third. The higher the level, the less fruit. The higher the fruit, the longer the fruit. It only plays a competitive role in nutritional components and has no economic value. If these high numbers are inactive, plants will be burdened prematurely for decades, leading to premature rest. Many people have no time to eat fruit. Plants are spring, and fruits are worthless.

So the growth of the upper part and plants occurred, and the plants were to be captured. Generally speaking, the top flower quilt stores 6-8 fruits, and the horizontal flower stores 3-6 fruits. Deformity, fruit, small fruit and weak bud will prevent nutrient waste. Plants can keep more and grow weaker. In addition, the inflorescence after fruit selection will be removed in time to promote the birth of new inflorescences.

Fourth, in order to increase ventilation and light transmission, there are too many.

At flowering stage, in order to improve ventilation and light transmission, promote fruit changes and prevent diseases, although leaves can increase ventilation and light transmission, they also reduce the photosynthetic area, which means that the nutrients made by leaves are reduced, but there are not enough nutrients for fruit expansion and supply.

At this time, there should not be too many leaves, and they should be removed according to the growth of plants and leaves. The leaves are thick, the plants are normal, the leaves can make sounds, and there are no pests and diseased leaves, which is in line with the ventilation and transmission conditions, because these leaves still help the plants, and each plant maintains effective functional leaves of 8- 12. In addition, you can also use high-type greenhouse film or high-type greenhouse film used by plants using carbon dioxide gas or clean the film in time to increase photosynthetic efficiency.

The fifth is deduction.

Many times our friends see other people's conflicts, so I think I'm going to deduct the greenhouse movie. In fact, you don't have to follow suit. According to the actual situation, determine the bending film, premature film bending will affect the temperature. The subsequent flower bud differentiation and normal growth and development of strawberry, although high temperature can accelerate strawberry, it will affect the further flower bud differentiation, which will reduce strawberry and make it feel weak.

Deduction time generally follows the principle of weak and long deduction and strong seedling. The temperature varies in different regions, starting from 10 in the north and from 1 1 to1in the south. When the temperature drops to 4 degrees? At 6℃, the first frost is more suitable at a place far from leax.
