Strawberry autumn planting note these points
Strong seedlings are selected for seedlings to grow seedlings that are robust and have many roots. The general seedlings must have at least four leaves and a stem about 1 cm thick. If the seedlings are purchased from a remote location, the large leaves of the plants should be cut off during cultivation, leaving only 2 to 3 leaflets in the middle. This will reduce evaporation of leaf water and increase its survival rate.
Soil preparation and fertilization About 15 days before the strawberry planting, we need to carry out soil preparation, deepen 30-40 cm deep, combine 4,000 kg of high-quality farmhouse fertilizer per acre, 15 kg of diammonium phosphate, 10 kg of potassium sulfate, and finally pulverize the soil. Fuping, the basis for doing squats or ridges. When it is done, it is 10 to 20 meters long, 60 to 70 centimeters wide and 10 centimeters high; when ridged, it is 50 to 55 centimeters wide, 15 centimeters high, and 20 centimeters wide.
Planting time The optimum temperature for strawberry planting is 15°C～23°C. It should not be planted prematurely, nor should it be planted too late. The temperature of planting soil too early will affect rooting and the survival rate is low. Tests have shown that the temperature is about 15°C, and the survival rate is 95%; too late planting the seedlings before winter is too small and the accumulation of nutrients is too little, which affects the output in the second year.
Planting method Planting direction should pay attention to the back of the seedlings bow to the side of the channel, so that the inflorescence in the same position, which is conducive to ventilation and light, but also easy to agricultural operations and management. Depth of planting is the key to the survival of transplanting. The planting depth must not be too deep or too shallow. The planting depth should not be too deep or too deep. The seedlings' heart is buried, which can easily cause rotten hearts and dead seedlings. When planted too shallow, the roots and stems are exposed, and it is easy to cause strawberry seedlings. Withered to death, the "deep not buried, shallow rootless" is the most suitable depth of transplanting.
Post-planting management for the seedlings to grow well after planting, promote flower bud formation, one should promptly remove the plants on the aging leaves and stolons; two to be applied in late September a nitrogen fertilizer, ammonium nitrate can be traced 15 kilograms per acre, Can also be combined with phosphate fertilizer; Third, timely irrigation, each irrigation water once after cultivating once to keep the soil loose and increase the temperature, which will help seedlings take root.
In the process of growth and development of disease-resistant and insect-resistant strawberries, gray mold, powdery mildew, leaf spot, and spider mite are often found. The prevention and treatment of gray mold can generally be sprayed with 0.3% lime sulfur mixture at the early stage of disease; when powdery mildew and leaf spot are controlled, it can be sprayed with 800 times liquid retinoic acid or 800-1000 times thiophanate-methyl; occurrence of red spider When it is harmful, it can be sprayed with 1200 times of 40% Zalcate Lactate emulsion for prevention and treatment.
