Management techniques of ploughing, weeding, fertilization, leaf picking and strawberry planting in watering

First, watering. On the day of planting, water the seedlings slowly immediately. Watering this time is the key to the survival of the seedlings. Because strawberries have shallow roots and are not resistant to drought, they must be watered as soon as possible. It is necessary to pour heavy water, water along the ditch, and thoroughly pour loose soil to facilitate the growth of the root system. When watering, it should be watered in the morning and evening to avoid high temperature at noon, affecting the growth of roots. If there are inverted or floating seedlings after pouring, they should be righted in time. Before slowing down the seedlings, the soil should be kept moist and watered every 1-2 days if necessary. About 7 days, when the strawberry heart leaves began to grow, the seedlings had slowed down, stopped watering, and the soil remained dry and wet.

Second, ploughing and weeding. After planting slow seedlings, ploughing and loosening soil was carried out for the first time to improve soil permeability and promote new roots. Due to the planting slow seedling stage, the strawberry root system is not firmly rooted, so the loose soil should be shallow, and the soil around the root system should not be loosened, so as not to damage the strawberry plant and root system. After each watering, when the topsoil seems to be dry, loosen the soil in time to prevent the soil moisture from evaporating rapidly and causing the soil to be hardened and impermeable. Weeds grow fast because of the moist soil, and weeds are removed when ploughing.

Third, fertilize. After slowing down the seedlings, if the seedlings are weak, 7kg urea can be applied per mu, and ABT rooting powder and NEB can also be applied on the leaves to promote rooting. If the strawberry seedlings grow well, they will not be applied. Because excessive nutrition of strawberry plants will delay flower bud differentiation. In late September, the terminal inflorescence began to differentiate. In order to promote the development of flower buds, nitrogen fertilizer could be applied once, about 10 kg per mu, combined with watering.

Fourth, pick leaves and buds. Old leaves and withered leaves affect stem expansion and are easy to induce diseases, so after slowing down seedlings, withered leaves, old leaves and newborn stolons should be removed in time. When strawberry plants begin to develop, exuberant axillary buds and stolons grow. In order to reduce the nutrient consumption of strawberry plants, the newly occurring axillary buds and stolons should be removed as soon as possible, but the leaves should not be removed too much, otherwise flowering and strawberry expansion will become slow. delay the harvest.
