How to improve the survival rate of strawberry planting
Improve the survival rate of strawberry planting to ensure that the whole plantlet is the basis for high yield. The following measures can be taken:
1. Appropriate pruning Before the planting, the old leaves and black old roots on the seedlings were cut off to reduce the leaf area, reduce the water transpiration of the plants, and promote new roots.
2. The medicinal roots are treated with drugs to treat the root system before planting, which can promote the occurrence and growth of the root system and improve the survival rate of the plant. If you use 10 mg / kg humic acid solution or 5 ~ 10 mg / kg of naphthalene acetic acid solution dipping root 2 to 6 hours, have a good effect. The immersion of roots with humic acid can restore the old root wounds to normal, and the new roots promoted are thick and short, and more secondary roots occur. In addition, ATP rooting powder and other plant growth regulators can also be used for strawberry root treatment, and promote root growth and development.
3. Choose the right time to plant the plant should be selected on cloudy days, so as to avoid the seedlings being exposed to the sun, and because the air humidity is relatively high, the leaf evapotranspiration is less, and the seedling period can be shortened to improve the survival rate. Planting on sunny days should be done in the morning or early evening.
4. Soil transplanted seedlings with soil transplants can reduce root damage, planting near distance, or planting a small number of good new varieties that will ensure survival, allowing the seedlings to shorten their seedlings and increase the survival rate. Soil transplanting is more effective in improving the survival rate in areas where there are insufficient seedling resources, poor irrigation conditions, and a relatively viscous or acid-alkali soil.
5. Note that planting depth is the key to the survival of strawberries. The planting is too deep and the seedlings are buried in the soil, which can easily cause the seedlings to rot. The planting is too shallow and the roots are exposed. It is not easy to produce new roots and it will cause the seedlings to die and die. The reasonable planting depth should be that the stems of the seedlings are flush with the ground, that is, the depth is not embedded in the roots, and the shallow roots are not exposed.
6. Grasp the method of operation When the strawberry is planted, dig the soil first, stretch the root into the hole, fill it with compacted soil, and gently lift the seedling to make the root system and the soil close together. Immediately after planting, set the root water. After watering, if there are roots or silt sprouts and plants that do not conform to the predetermined direction of inflorescence, they should be adjusted in time or replanted. Leakage plants should be promptly filled with water to ensure the quality of the whole planting and planting.
7. After properly watering the seedlings and planting, set the root water to drench. During the 3 days after planting, water should be poured once a day. During the period of seedling, irrigation should be performed according to the humidity in the field to maintain the humidity. After colonization and survival, appropriate cultivators can be used for cultivating and seedlings.
8. Covering the shade After the planting, in case of a sunny day, shade measures can be used to cover it with curtains, plastic yarns, and branches with leaves. Conditions can be used plastic shade nets, green or silver-gray plastic film cover into a temporary shelter to shade, live in time after the timely airing, pay attention to ventilation and hardening of seedlings, so as not to suddenly remove the shading when burning seedlings, 3 to 4 The sky can be withdrawn afterwards.
