Right now, the disinfection of soil in strawberry greenhouse is almost near the end, and the next strawberry planting season is about to begin. Strawberry growers must be aware of the need to pay attention in the planting process in order to improve the survival rate of planting.
Traditional soil cultivation
â—† The land where the strawberry was first planted;
Mu uses 2 tons of organic fertilizer, 40 kg of calcium sulfate and 10 kg of potassium sulfate. Continuous cultivation of strawberries for more than 3 years to detect soil nutrients can be reduced depending on the amount of basic fertilizer.
â—†Application of Biological Bacterial Fertilizer
The type of the main bacteria should be distinguished. It is advisable to apply it in advance and apply it before the application of hydrazine. It is best not to concentrate the bacteria in the phytoseinum by the bacteria that use the oxygen-absorbing mechanism.
Substrate cultivation
Due to the strong water permeability of the matrix in the substrate cultivation, granule fertilizers and fast-dissolving fertilizers are generally not recommended for use in basal fertilizers. Slow-release coated fertilizers can be used. There are many types of fertilizers that strawberry growers can use selectively based on slow release rate and coating conditions.
â—† New substrate
In the early stage of use, 10-15 kg of high-quality commercial organic fertilizer can be incorporated into each cubic matrix. If the quality of organic fertilizer is not known, it is best not to mix it. There is no fertilizer in the matrix.
â—† Multiple-use matrix
It is best to add a new substrate and turn it upside down. If the matrix itself is very fine and poor water permeability, it is best to add the right amount of perlite. More than three years generally increase by 1/5.
It is best to add perlite after immersion in fresh water for substrate cultivation. Before the planting, be sure to thoroughly wash the matrix thoroughly, so that the matrix exudate is not cloudy.
Planting time
In 2017, there was more rain than in the same period in previous years. Strawberry growers had better push the planting time back and choose to plant between September 1 and 10, so the survival rate is high. The best choice for colonization is after 3 pm, and it will enter the cool time of night after planting, which is more conducive to strawberry seedlings. Try to avoid planting in the morning, because the high temperature at noon and afternoon immediately after planting is not conducive to slow seedlings. Try not to use shade nets unless the sun is full. Shade nets must be removed at night.
Seedling treatment
â—† bare root seedlings
Bare root seedlings cooling and disinfection
Please do not plant new seedlings directly. It is best to place the strawberry seedlings on the open ground without soil. Rinse the strawberry seedlings with a pipe for about 5 minutes, especially the roots. On the one hand, reduce the pathogenic microorganisms attached to the seedlings. Strawberry seedlings to add water. The standard is that the leaves cannot carry mud, and the washed seedlings are immediately moved to a place without wind and shade and covered with a moisturizing quilt to prevent heating.
When planting, the strawberry seedlings were soaked in the 3000 times solution of 25% azoxystrobin for 2 minutes below the rhizome, and finally the strawberry seedlings were all put into the liquid medicine.
Seedlings rejuvenate
If the newly obtained strawberry seedlings are too fine or have wilted or are already hot, it is best to rinse the seedlings and then simply perform a prosthesis. If the seedlings are selected, they can be sun-dried in the morning and slightly shaded in the afternoon. The high-lying plots do not contain water. Implantation tanks with matrix, the strawberry seedlings can be loosely placed, the leaves should not be too close, if necessary, can be used to isolate the bamboo shoots to prevent heat. From the bottom of the water injection to the seedling roots above the Ministry can be, and then do not easily water, each watering is best carried out around 5 o'clock in the morning, all using the bottom of flooding, watering from the top is prohibited. After a period of three days, new roots can be produced and plants can be planted in the greenhouse.
Planting
Different strawberry seedlings are also different in finishing strawberry plants. The first is the root system. For the appropriate short cut of the root system, keep the length of the root system at 16 to 18 cm. Followed by the leaves, it is best to lose one-third of the entire leaf when planting, so that the leaves can stand upright.
Here, it is emphasized that in principle strawberries should not be easily wounded. In particular, the petiole and stolons of the rhizomes should not be easily removed. If they get in the way, petiole and stolons of 15 cm should be kept.
â—† Matrix seedlings
Matrix seedlings were divided into matrix strawberry seedlings and substrate plug seedlings. These seedlings have the advantages of slow seedlings, etc., but it is easy to grow prematurely or to significantly cut off. Before planting, the strawberry root matrix should be properly loosened and the roots should be properly shed. However, do not shake down all the substrates. This will lose the advantages of saplings. Longer roots can be appropriately shortened, and the strawberry pods can be quickly colonized in the liquid during planting.
Kinds of seeds before the investigation of pests and diseases
The most important thing for strawberry seedlings with bare root or sapling seedlings is to check whether the strawberry seedlings have residual powdery mildew or spider mite symptoms before planting. According to the remaining lesions in the disinfection process by adding the appropriate agent for protection. The sapling seedlings focus on the control of red and white spiders. It is recommended that plants that are infested with red spiders are best treated with oxazophthalonitrile suspensions.
Strawberry colonization
Planting options After 3 pm, it is best to plant the strawberry seedlings diagonally upwards and planting the ditch after confirming the arching position. The roots of the strawberry planted after pouring the planting water will be exposed to 1 cm, and will be exposed again in the next morning. The roots of the centimeter are covered and watered. The first day's exposure to 1 cm of the root system was to allow the roots of the newly planted strawberry to breathe oxygen. This method can greatly improve the survival rate of strawberries, and does not bury the core to prevent bud blight and weak seedlings.
In the cultivation process, the trough is used to cultivate the trough. A 15 cm deep trough is cut under the trough, one side of which is upright. The strawberry seedlings are laid on the same scale as the green onions, and the soil is buried in the strawberry seed. Two-thirds of the roots of the seedlings were slightly compacted and watered. Irrigation with slow filling, natural infiltration is appropriate. Strawberry seedlings do not require erect planting. The next day covered the rest of the root system, so that the survival rate of strawberry colonization was high.
Seedling management
Do not do anything other than watering during this time, including making up seedlings. The best way to make up the seedlings is to plant surplus seedlings in the nutrient bowl during the planting process. When the strawberries are planted for 20 days, they can be used together to make up the seedlings. Do not fill seedlings every day to water, otherwise it is easy to appear powdery mildew.
Do not spray any foliar fertilizers during the period of seedling easing. All fertilizers or pesticides have a certain burn effect on the foliage. After the new seedlings are released, the leaves are sprayed with fertilizer.
The planting water after planting is soaked with a large water sinking method. After pouring the water, it is best to inject hymexazol initially to prevent fusarium wilt.
Post-emergence management
â—† It is very important to go to the old leaves after easing the seedlings after easing them. To early weaken the growth of strawberries, serious will cause dead seedlings; to go late, the old leaves will inhibit the occurrence of new leaves, is not conducive to plant growth. Therefore, when you go to the old leaves, you must follow the development of two new leaves to remove them, and you cannot remove too much at once. Otherwise, the wounds are too much and too much, and the bleeding fluid weakens the growth of the strawberries and affects the differentiation of flower buds in strawberries.
â—† After the seedlings grow slowly, the control of the strawberry seedlings should be controlled after the seedlings are slowly growing, especially the sapling seedlings, which grow quickly and easily, and are prone to many lateral shoots. Do not use hormones to treat strawberry seedlings. It is best to spray amino acid potassium or cool the leaves.
