Method for plan tomato in saline-alkali land

Strengthen water and fertilizer management, dig deep into the soil and apply more bio-organic fertilizer to make the root system grow well and buffer the drastic change of soil moisture; Reasonable watering, avoid alternating dry and wet soil, especially to prevent excessive watering after a long drought; Greenhouse vents should avoid falling into rain; When the temperature drops suddenly, more attention should be paid to soil moisture management to avoid excessive humidity change.

The cracking of persimmon fruit in saline-alkali soil is also related to calcium and boron absorbed by plants. Insufficient supply of calcium and boron will cause fruit cracking, so it is necessary to supplement calcium fertilizer and boron fertilizer in time and adjust the proportion of various nutrient elements in the soil. Nitrogen fertilizer and potassium fertilizer should not be too much, otherwise it will affect the absorption of calcium by plants. Drought will affect the absorption of calcium by plants, so it is very important to water evenly.

Paying attention to environmental regulation, preventing pericarp from aging and avoiding direct sunlight on fruit shoulders are effective measures to prevent aging: proper shading; Leave three or four leaves when removing the core, and leave the top and side branches appropriately to reduce the air humidity and shorten the dewing time of the fruit surface.
