Improve the survival rate of strawberry planting and ensure that the whole seedling is the basis for high yield. The following measures can be taken:
1. Proper pruning removes old leaves and black roots from the seedlings before planting to reduce leaf area, reduce water transpiration, and promote new roots.
2. The drug solution is root-treated with a drug before the planting, which can promote the occurrence and growth of the root system and increase the survival rate of the plant. If you use 10 mg / kg of humic acid solution or 5 ~ 10 mg / kg of naphthalene acetic acid solution for 2 to 6 hours, have a good effect. Rooting with humic acid can restore the old root wounds to normal, and the new roots that are triggered are thick and short, and more secondary roots occur. In addition, plant growth regulators such as ATP rooting powder can also be used for root treatment of strawberries to promote root growth and development.
3. Choosing a favorable time for planting should be planted on a cloudy day, so as to avoid exposure of the seedlings to the sun, and because the air humidity is high, the leaf transpiration is small, the seedling period can be shortened, and the survival rate is improved. Planting in sunny days should be done in the morning or in the evening.
4. Transplanting soil with transplanted seedlings can reduce root damage, and planting a small number of excellent new varieties that can be planted at close range or survived, which can shorten the seedling stage and increase the survival rate. Soil-transplantation has a more significant effect on improving survival rate in areas where seedling resources are insufficient, irrigation conditions are poor, soil is more viscous, or acidity is more alkaline.
5. Note that the depth of planting depth is the key to the survival of strawberries. If the planting is too deep, the seedling heart is buried by the soil, which is easy to cause the seedlings to rot; the planting is too shallow, the roots are exposed, and it is not easy to produce new roots, which will cause the seedlings to die dry. The reasonable planting depth should be that the stem of the seedling is flush with the ground, that is, the depth is not buried, and the shallow is not exposed.
6. Master the operation method When planting strawberries, first excavate the soil, place the roots in the holes, then fill in the fine soil and compact the seedlings so that the roots are in close contact with the soil. Immediately after planting, water a fixed amount of water. If there are dew roots or silt seedlings and plants that do not meet the intent of the inflorescence after watering, they should be adjusted or replanted in time. The plants should be replenished with water in time to ensure the quality of the whole seedlings and planting.
7. After the reasonable watering of the seedlings is planted, the root water should be poured. Water should be irrigated every day for 3 days after planting, and water should be kept according to the humidity in the field during the slow seedling period to maintain humidity. After planting, it can be properly cultivated to dry seedlings.
8. Covering the shade and planting the sun, if it is sunny and hot, you can use shading measures, covered with curtains, plastic yarn, branches with leaves and so on. Conditional plastic shading net, green or silver-gray plastic film can be used as a temporary shed to cover the shade. After the survival, it is necessary to dry the seedlings in time, pay attention to the ventilation and refining, so as to avoid burning the seedlings when the shame is suddenly removed, 3~4 Can be shed after the day.
