1, fig fertilizer. The proportion of fertilizer is calcium: nitrogen: potassium: phosphorus = 1.43:1.00:0.90:0.30. The ratios of nitrogen, phosphorus and potassium are three factors. The young tree is 1.0:0.5:0.7, and the adult tree is 1.00:0.75:1.00. should. Basal fertilizers, preferably organic fertilizers, are generally applied during the dormant period after defoliation and require 1 kg of organic fertilizer 1.0-1.5 kg. Open or ditch is applied below the branch. On the basis of applying basal fertilizer, top dressing (land application or foliar spray) should be conducted 5 to 6 times a year. In the early stage of growth, nitrogen is the main fertilizer. During the later period of fruit maturation, phosphorus and potassium fertilizers are mainly used, and calcium fertilizer is added (land application and leaf spray are all available). Soil topdressing should be combined with watering, topdressing with trenches, and soiling with cover soil, and surface spread is not advocated. During fruit growth and development, foliar spray of 0.2% potassium dihydrogen phosphate and other foliar fertilizers can be applied to increase fruit size and increase yield.
2, fig watering. The moisture must be added in time according to the fig. The main water-requiring period of figs is the germination period, the long-term speed of new shoots and the fruit growth and development period. In addition to conventional irrigation methods and irrigation, irrigation methods are available for drip irrigation and sprinkler irrigation. It is not advisable to add too much water to the figs at one time, especially during ripening period of the fruits. To avoid excessive changes in the dryness and humidity of the soil, stable and appropriate soil moisture should be maintained at all times, so as not to increase cracking. In addition, figs are strong in drought resistance and weak in resistance. In the rainy season, special attention should be paid to timely drainage, and timely reclaiming of loose soil after the rain.
The fig water and fertilizer management measures are shared here with everyone. I hope this article will help everyone.
