The pH value of the soil is measured with a pH test paper. When the pH value is greater than 6.5, especially when the pH is greater than 7, the soil will inevitably lack trace elements. Can be applied per mus with borax 1-1.5 kg, 2.5-3 kg of zinc sulfate, 3-3.5 kg of ferrous sulfate, 2.5-3 kg of manganese sulfate, 5 kg of magnesium sulfate (only one application per year) . Foliar can also be sprayed with trace elements containing elements such as boron, zinc, iron, manganese, magnesium, etc. Usually, every 25-35 g of trace fertilizer is applied to 15 kg of water and sprayed once every 5-7 days.

Why don't tomato color
Experts answer: If the planting density is too high, it will cause mutual shade between plants, so that the fruit can not get enough light, resulting in poor fruit coloring. Therefore, the planting density should be controlled. The light transmittance of the film can also affect the light. It is necessary to choose a high light transmittance tent, and often wipe the mold.
