The hoe supplier explained the precautions for tomato fertilization

Tomatoes, also known as tomatoes, can be used as both vegetables and fruits as well as fresh fruits. They are popular with customers all over the world. The market demand is large. Today, we will follow the hoe manufacturer to learn and train the technical points of tomato fattening.

1. Apply sufficient basic fertilizer. Compost organic fertilizer is mainly used for 2-5t/mu, and organic fertilizer is added appropriately according to different maturity and planting stage of tomato varieties. Mature varieties: phosphate fertilizer 25-30kg/mu, potassium sulfate 35-40kg/mu, urea solution 15kg/mu. The dosage of zinc sulfate is 1kg/mu; Borax 0.25kg/mu; Use 3% phoxim phosphate powder 3-5 kg/mu.

2.1 10-15d after tomato transplanting and topdressing, in order to promote the early growth of seedlings, 8-10kg/mu of special vegetable fertilizer (Lofgen good barrel fertilizer) can be used together with washing, or 300 times of root thinner can be used to promote the growth of rhizomes (more developed rhizomes, more secondary roots), raise seedlings, and resist root rot.

2.2 Before flower bud differentiation, apply 4kg/mu of Schloff Faerie series products (high phosphorus) for the second time, which can be used with 600 times of nano product series (nano B) thinner to promote flower bud differentiation, protect flowers and improve seed setting rate.

2.3 The third topdressing can topdressing 10kg/mu of Schloff barrel fertilizer (good fruit) when the ear fruit is just growing, and the actual effect is very good with 4kg/mu of high potassium fertilizer spirit. It can achieve the practical effect of fruit expansion, high yield and drought resistance improvement.

2.4 At the fourth topdressing, the spike is close to the fruit, and the second spike is close to the fruit. When the third spike is big, the main stem enters the peak production period. Schloff uses 10kg/mu fertilizer in barrels, accompanied by 4kg high potassium fertilizer spirit. Later, according to the growth of the main stem and the fertilizer supply of the soil, high potassium fertilizer elf (4-6 kg/mu each time) can be applied once or twice, which can not only increase the fruit setting period of cola fruit, but also avoid aging and limit the yield. Irrigation and topdressing, and proper soil cultivation can promote the growth and development of tomato rhizomes. * In the case of potassium deficiency in the soil, the application of potassium fertilizer in the second half of the period plays a key role in the uniform color of tomato fruits, reducing rhombic fruits, and improving the quality of fresh fruits.

3. Leaf fertilizer application: sprout, transplant for half a month, spray Luofu 205 and leaf fertilizer 20ml/barrel; The amount of fertilizer applied at the early stage of flower bud differentiation is the same as above, and the amount of fertilizer applied with Galev nano boron is 25ml/barrel; Spray once in the high yield period (in the second half of tomato growth and development, the growth and development of leaves and stems have just begun to ease, so as to win the yield in the second half and avoid aging). To sum up, the above is the key to tomato fattening technology. In the whole process of grain crop planting, fattening is a very critical stage, which needs to be grasped.
