Fertilizer characteristics
Tomatoes to need NPK ratio for 1-0. 2:1. 7, tomato like fertile soil, tomatoes before flushing, demand for nitrogen is bigger, and after flushing, plunging demand of nitrogen fertilizer, the demand for potash.based on the physiological characteristics of tomato, attention should be paid to in each growth stage in terms of fertilizer, fertilizer at the same time, the timely supply to decrease caused by unreasonable fertilizer tomatoes physiological deficiency problems.
The basal use
Colonize the tomatoes before, to fully decomposed organic fertilizer, for the whole family during the nutrition supply, and increasing organic fertilizer to improve soil, increase soil granular structure, improve the permeability of soil, for the root system and create a good environment for the growth and development of conditions, promote strong root and seedling, increased plant resistance.
Timely according to
Tomatoes to the front of the flushing, normally not fertilizer after engraftment.When the first group of fruit enlargement, while watering fertilizer, during the second and third group of fruit enlargement, after applying to increase k content, good for plant growth and development.And cooperate the use of bio-bacterial manure, help promote root growth, control the occurrence of harmful bacteria, control the root disease and premature aging, improve the yield and quality.
Reasonable spray fertilizer
The rational use of foliar fertilizer can solve many problems, it can have the effect of top dressing, because of plant physiological disease caused by deficiency, can be added by spraying foliar fertilizer.For example: foliar spraying boron or borax 400 times, 1500 times the speed can effectively prevent the dehiscent fruit phenomenon and improve the quality of flower bud differentiation;600 times foliar spraying nucleotide foliar fertilizer mixed with zinc sulfate 2000 times, can effectively prevent the tomato leaves yellowing, and can enhance the resilience of tomato;In tomato birth later period, 400 times foliar spraying cytokinin mix with 300 times the potassium dihydrogen phosphate, can prevent premature aging plant, yield and quality were increased significantly in the late.
