What are the key points for attention in transplanting strawberries? Doing these well can improve the survival rate.

In the past two days, many strawberry growers have been busy raising seedlings and transplanting, so what are the key points worth paying attention to? Let's talk about the small details of the seedling period. Mastering these can improve the survival rate.

Reasonable micro-control

If the seedlings are highly tender and prosperous, micro-control should be carried out 5-10 days before seedling emergence, because the survival rate of high-tender seedlings is low, and if there is a high temperature during planting, such seedlings will easily die in the sun, so thriving seedlings need to be microcontrolled to improve the survival rate after transplantation. Prochloraz (10g) was used to control the growth. At this time, it can only be micro-control, not overuse.

Rational use of marriage medicine

It can be used in combination with tebuconazole (tebuconazole) 5-10 days before seedling emergence. Prochloraz) 10g. If the seedlings are not thriving, then 70% thiophanate wettable powder 1000 times, or 70% chlorothalonil wettable powder 600x, 25% carbendazim wettable powder 400x can be sprayed and sterilized; 4.5% cypermethrin EC 1500 times, 8% medium guarantee 2000 times solution, comprehensive control of anthrax, root rot and beet armyworm, red spiders, aphids and other diseases and pests.

Rational watering

In order to rise the seedling smoothly, the soil of the seedling field should be loose and moist; if the soil is dry at the seedling stage, a small amount of water should be irrigated in advance and the seedling should be raised after the soil of the seedling bed is moist. The seedling depth should not be less than 15 cm to ensure the integrity of the seedling root system. If the seedling is too shallow and root injury is too much, planting is not easy to survive. After planting nearby after coming out of the nursery, the seedlings should be brought with soil, so that the survival rate is the highest after planting. If it is to be transported over a long distance, attention should be paid to packing and cooling. The roots of seedlings are wrapped in woven bags, and attention should be paid to avoid the loss of water in strawberry roots and prevent root aging.

Prevent the disease from entering through the wound

When digging seedlings, take the stem base by hand, do not push too hard, handle it gently, and do not pinch the heart of the seedling. At the same time, try not to cut off the main root, create as few wounds as possible in the process of planting, and do not tidy up strawberry seedlings within 15 days after planting to avoid root injury and bacterial infection.

Finishing and grading of strawberry seedlings

The strawberry seedlings should be sorted out and graded before planting, the big and small seedlings should be separated, the strong seedlings should be kept, and the weak and diseased seedlings should be eliminated. If the seedlings cannot be stored in a cool and ventilated place along with the planting, they should not be piled up to prevent strawberry seedlings from being killed by excessive heat. To spread out to store, can ensure good heat dissipation.

Each seedling retains 4-5 healthy leaves, and the old and diseased leaves can be cut off with scissors, leaving only one petiole. When finishing seedlings, it is not suitable to break off the excess leaves by hand, otherwise it is easy to cause wounds in the basal stem and be infected with root rot, Fusarium wilt and other diseases.

Transplanting with soil

If transplanting with soil is the best, if it can not transplant with soil, it is the bare root seedling purchased, then the root length retains 13-16cm when planting, and it is easy to nest the root if the root is not stretched. If it is too short and harms too many capillaries, it is not conducive to slow down the seedling. After receiving the purchased seedlings, it is necessary to slow the seedlings and then transplant them. It is best to make preparations for planting seedlings, including making beds, covering beds, shading and personnel arrangements, and then carry out the work of raising seedlings, and the production seedlings should be planted as soon as possible.

Medicament dipping in root

Dipping the medicine in the root can prevent a variety of strawberry diseases. Soak the roots of strawberry seedlings in 70% methyl topiramate wettable powder plus carbendazim plus carbendazim for 1-3 minutes. It is important to avoid soaking the leaves. Wait for the natural drain before planting. Note that the prepared solution is soaked only once and can not be reused to avoid cross-infection of the disease.
