Strawberry planting technical measures
Prepare the ground before planting The soil is plowed, raked, and ridged after disinfection. The use of drip irrigation can reduce soil compaction and poor permeability caused by watering. In winter, it is very beneficial to maintain ground temperature, reduce humidity in the greenhouse, and prevent disease from occurring. In order to avoid the impact of strong light and high temperature on the slow seedling and survival rate of strawberry seedlings during planting, sometimes a shading net can be laid one day before planting to reduce light and temperature. Choose quality seedlings Select seedlings to choose disease-free seedlings with good growth and strong fibrous roots. Generally, seedlings must have at least 4 leaves with a stem thickness of about 0.6 to 1.2 cm. If seedlings are purchased from a distant field, the large leaves around the plant should be cut off during cultivation, leaving only 2 to 3 small leaves in the middle, which can reduce the evaporation of leaf water and improve its survival rate. When planting, the strawberry seedlings should be soaked with a fungicide to eliminate the germs carried by the seedlings. Detailed explanation of colonization technology Planting time The planting time of greenhouse cultivation should be determined according to the degree of differentiation of top flower buds. When the flower bud differentiation rate reaches 50%, it can be planted. Usually in late September, choose to plant in the evening or cloudy. It is worth noting that the strawberry has a survival rate of only 10% when it is planted at a temperature of 30 ° C; the survival rate is about 50% at a temperature of about 25 ° C; the survival rate is about 95% at a temperature of about 15 ° C. The survival rate of strawberries planted in summer or early autumn is very low, which brings serious losses to production, especially for seedlings imported from other places. The problem is more prominent. Avoid premature planting. Generally, the optimum temperature for planting is 15 ° C ~ 23 ° C. Planting direction When planting seedlings, we must pay attention to the planting direction of the seedlings. The back of the strawberry seedlings must face the ditch on both sides. In the future, the ears will be drawn to the sides of the ridge, which is conducive to ventilation, management and harvesting. Density and reasonable depth are important conditions for obtaining high yields of strawberries, generally about 6000 to 8000 plants / mu. For specific planting density, refer to the introduction of each variety. Two rows per ridge, planted in triangles, row spacing 25-30cm, plant spacing 15-20cm. The depth of planting is the key to the survival of the strawberry. The above is not buried, and the roots are not exposed. Planted too deeply, the heart of the seedling is buried in the soil, causing rotten heart; too shallow roots are easy to die. If rooting or burial occurs after irrigation, it should be replanted in time. Disclaimer: Some articles on this website are transferred from the Internet.
