How to use bio-organic fertilizer for strawberries

Strawberry is a plant that takes fruit as edible. The fruit is bright red and bright, tender and juicy, sweet and sour palatable, and has high nutritional value. Strawberry is planted in our country from Heilongjiang in the north, Guangdong in the south, Shanghai in the east and * in the west. In a year, the physiological functions of strawberry organs change regularly with the change of season, which is generally divided into five stages: initial growth period, flowering and fruiting period, vigorous growth period, flower bud differentiation period and dormancy period. Strawberry root system is fibrous root, the distribution is shallow, 70% of the root system is distributed in the 20 cm deep soil layer. Strawberry is a water-loving and fertilizer-loving crop, which requires strong fertilizer and water conservation capacity, good ventilation and loose texture of sandy loam. Reasonable fertilization should be applied during the whole growth period to ensure robust plant growth, more flowering, more fruit setting, good fruit taste and high yield. Strong seedlings are the basis of high quality, high yield and high efficiency. Strong seedlings accumulate more nutrients, developed roots, survive quickly after planting, flower buds differentiate and are full, and can produce large and many fruits. Applying sufficient basal fertilizer is the basic condition for strawberry seedlings to be strong. Choose loam plots rich in organic matter and various minerals instead of tomatoes, potatoes, eggplant, peppers, beets, peas and other crops. Before planting, prepare the land and make the bed, turn the soil 30 meters deep, and apply sufficient base fertilizer at the same time. Generally, 200 kg of bio-organic fertilizer is applied per mu, 10 kg of urea, 25 kg of calcium superphosphate and 10 kg of potassium sulfate are applied. On the basis of sufficient base fertilizer, 20 kg bio-organic fertilizer was applied per mu after strawberry planting or survival in the north to promote the root growth of the plant. In Jiangsu and Zhejiang areas, fertilizer was applied once after planting, and 20 kg of bio-organic fertilizer per mu was applied in mid-November or early December. Strawberry fields without sufficient basal fertilizer should be fertilized three times. For the first time before sprouting in spring, 30 kg bio-organic fertilizer was applied per mu to promote green growth and inflorescence development. Before flowering for the second time, 20 kg bio-organic fertilizer per mu was applied to meet the nutrient needs of accelerated plant growth and flowering and fruiting. The third time after fruit harvest, 40 kg bio-organic fertilizer per mu was applied to supplement the loss of soil nutrition, restore the plant growth potential, and carry out the second vegetative growth to promote flower bud differentiation.
