When to water an apple orchard What is the amount of watering and where is the watering? What to loo

We can water between 80% when germination, don't water too much, it will cause the leaves and seedlings to rot, when flowering, they already have some water at the bottom of about 60% of the water, after bearing fruit, to maintain their daily moisture; Special attention is paid to the fact that we water them according to their daily weather conditions.

Germination stage: soil water content should reach 70-80% of field water holding capacity; Flowering period: The soil water content should reach 60-70% of the field water holding capacity. It should be based on the water requirements of apple trees at different phenological stages (refer to Part 1), climatic characteristics and soil moisture status.

The first time to water the apple orchard is in the spring, that is, in April and May, when the apple trees can be quickly resurrected, and the maximum amount of watering should be reached in the summer, with an average of 30 liters per tree per watering. It is important to note that the watering process should be adapted to the weather.

Apple is a very common fruit on the market, and it is also the first choice of many people, it is very nutritious, and it tastes sweet and sour. When it comes to the annual break, it is the season of apple picking, and the yield is generally very high, but apples need a lot of water in the process of planting, and it is necessary to reasonably grasp the watering period, and water regularly throughout the year. <>

In the process of planting apple trees, if it is spring and autumn, the climate is relatively suitable, and the rain is sufficient, so there is no need to water too much, generally watering once every two or three days, which can basically meet the water needs of the trees. In the summer, when the temperature rises and the land is relatively dry, it is necessary to water the trees many times so that they can have enough water, and they basically need to be watered every day. However, in the winter, the temperature is relatively low, so there is no need for manual watering, so it is about once a week or so, as long as you can make sure that the soil is moist.

Every year when the rainy season comes, everyone should remember that you must not water casually, because at this time, the apple trees are already very watery, and you can only dig drainage ditches. However, during the dry season, the apple trees should not be short of water, so a deep well can be dug next to it to water the trees and ensure the normal growth of the trees. Therefore, the watering period of apple trees is never fixed, it can only be changed according to the changes in the surrounding environment, and it is necessary to water reasonably according to the surrounding weather and temperature.

When watering apples, it is necessary to have the right amount of water to keep the soil at the roots of the apple tree moist so that the tree can grow and develop properly. If the upper layer of soil is only wet during watering, then the purpose of watering cannot be achieved at all, and multiple irrigation is required. At least 50 to 60 cm below the soil should be soaked each time you water.

Before watering, it is necessary to know the amount of water to be discharged and the amount of watering according to the local climatic conditions and the amount of recent rain.

In the growth period of the fruit, it is definitely necessary to water, pay attention to the germination period, pay attention to the fruit expansion period, these times all need to be watered.

It can be watered before and after the flowering period, it can also be watered at the germination stage, it can also be watered during the flower bud differentiation stage, and it can also be watered when it loses moisture; Watering first and then fertilizing, if the precipitation is uniform throughout the year, it is okay not to water, if there is no precipitation throughout the year, it is necessary to irrigate to meet the water requirements of apple trees, watering before budding, can reduce the damage of spring cold to flowers and fruits.

Apple trees should be watered more when they sprout, and apple trees should be watered less when they bloom, because too much watering is especially easy to cause fruit drop, and apple trees need to be watered more when they bear fruit, so that the apples can grow bigger.

Be sure to water a small amount and many times, do not water too much each time to prevent root rot, and also pay attention to ventilation, pay attention to the time of watering, and try not to choose noon watering.

During the planting period, it is necessary to water at 5 p.m. every day, and it also needs to be watered 3 or 4 times a week, so as to ensure the moisture of the land and also improve the growth rate of apples.

It is very suitable to choose to water once every two to three days, and in the summer, you can choose to water one to two days, because it absorbs quickly in summer.

At this time, we must carry out effective watering according to the needs of the jujube tree, pay attention to water-saving irrigation, and also protect moisture and prevent drought, and at the same time, we should also do a good job of timely drainage.

At this time, it is better to choose the morning and afternoon time slots to water the apple trees.

If the soil is dry at that time, be sure to water it in time, but don't water too much at once.

For example, fruit trees that have not been applied base fertilizer in autumn can be frozenly applied with base fertilizer immediately after freezing and melting in spring, and can also be applied to farm fertilizer in the farmhouse, and then fully wateredGive better nutrients to the growth and development of new roots, germination and flowering of apple trees in spring, so as to ensure that the fruit trees are withered, slow germination, dried flowers, and inferior fruit setting rate caused by insufficient nutrients. When the leaves of the apple tree are raised, the mites that have passed the winter eat and lay eggs in front of the flower buds, and the time when the top bud of the iphone is separated and slit happens to be the hatching period of the winter eggs, then it is necessary to do a good job in the prevention of mites, <>

Generally, the medicine is liquid or crystalline dimethoate, and 70% of the chemical fertilizers such as mites or sulfur suspension agents are sprayed when the flowers are outdated. You can use fertilizer such as pig manure to carry out fertilizer, 1 mu of land should be 3000kg or less, and then every 3 years to apply. If the irrigation method is applied, the chemical fertilizer at this time can be water-soluble organic fertilizer, and the nutrients are dissolved in water, and watered into the seedling base with water.

Water injection can choose the irrigation method, this irrigation method is more than 60% higher than the traditional infiltration irrigation comprehensive energy saving efficiency, the main data information is as follows: the traditional infiltration irrigation of an acre of land to consume 50 cubic meters, and sprinkler irrigation is only 5 square meters around, <>

But it's likely that more irrigation will have to be done. Circumcision of apple tree stems during flowering period can improve the fruit setting rate; Circumferential cutting of the tree stem in mid-June can promote flowering and increase the annual yield. It should be noted that the key to circumcision is that for 3 5-year-old trees, trees with low growth and development are generally not suitable for circumcision.

Circumferential cutting method: use a sharp knife to cut the roots of the tree tightly around the tree pole, temporarily block the sieve tube, and prevent nutrients from being transported downward, so as to improve the level of nutrient content of the branches, and then improve the fruit setting rate and promote the slow elimination of flowers.

In June, it is better to use light fertilizer to prepare potassium sulfate compound fertilizer around 20:10:20.

1 mu of fertilizer amount of 100-150 kg is the most suitable, in the trunk field projection around the ditch use, fertilizer immediately after sprinkling. Apple trees generally do not need to be circumcised, and the wounds are very susceptible to viruses and perishable roots. The key to circumcision is best when small fruits occur after flower failureBy temporarily cutting off the sieve tube in the roots, it can block the transport of photosynthetic nutrients to the stem and increase the fruit setting rate.

Since more liquid fertilizer is necessary during the fruiting period, fertilizer and watering should be applied after circumcision.

It needs to be watered at least once a week to ensure the normal growth of the apple tree. The advantage of watering is that it can provide water-filled water, which can make the soil here more fluffy and soft, and can also make the soil more water, which can ensure the supply of nutrients, which may lead to some diseases in the soil, and may also cause too many earthworms to envy, which may cause damage to the roots, which may cause the roots to be soaked and rotten, which may affect the harvest.

In the case of apple trees, you can generally guess the sail every 7 or 10 days, so that you can water it once; There is also to adjust the watering according to the changes in the weather, and then to adjust the watering, watering, in fact, it will help the apple tree to sprout and blossom and bear fruit, and in this way, it will not affect the yield, but if Suihui teaches too much, it is easy to have rotten roots.

Generally, the second is that you need to water every three days, and the advantage of frequent watering should be that the growth will be better, but the disadvantage is that the fruit is not so big.

1. Water once every 2-3 days in spring and autumn. In the spring and autumn season, the climate is still more suitable, at this time, we don't water too much, generally choose 2-3 days to water once on it, such a water supply is enough.

2. It is best to water once a day in summer. In summer, the temperature is still relatively high, at this time we need to water more, so that the apple tree can absorb enough water, this we need to know, but also appropriate watering.

3. You can only water once a week in winter. In winter, the temperature is relatively low, at this time, we can not water more, generally watering once a week, when watering, make sure that the soil is moist.

4. Watering needs to be stopped during the rainy season. When the rainy season comes, we must not go to the banquet to water, at this time, the water is too much, we can not water, can only dig the Zhaoyin Canal to release water, so as to avoid the phenomenon of some rotten roots in the roots, guessing this is particularly important.

5. Find ways to water properly during drought. In times of drought, apple trees cannot lack water, we can dig deep wells to produce water, we can water less, at least to ensure their normal growth.

6. Choose the amount of watering according to the overall environment. Whether the environment is good or not is connected to the amount of watering, it is generally necessary to water in time according to the necessary factors such as weather and temperature, which we need to pay special attention to, so that it can be regarded as a real reasonable watering.
