If you really want to grow well, go buy some fertilizer.
Because there is less food, fertilizer does not grow at all.

Anonymous users2024-01-22Causes of yellow leaves at the seedling stage of corn:
1. Corn seedlings are drought tolerant but not waterlogged, and excessive watering leads to poor root respiration and stunted growth, so the leaves turn yellow.
2. Corn seedling blight.
2. Potassium deficiency. Potassium deficiency in base fertilizer leads to potassium deficiency in corn. Potassium deficiency is the yellowing of the edges of corn leaves.
3. Nitrogen deficiency. Corn requires very little nitrogen fertilizer at the seedling stage, so the possibility of nitrogen deficiency is low. Unless your land hasn't been nitrogen-fertilized for years, or it's newly cleared. Nitrogen deficiency is the yellowing of the veins of corn leaves.
4. Drought. The temperature is too high, the water is seriously insufficient, the water loss of corn is accelerated, and the chlorophyll content is reduced. This is the direct cause of corn yellow leaf disease.
The solution is to immediately apply compound fertilizer, the amount can not be too large, and it is better to use 50 kg of compound fertilizer per mu. Then water immediately, the water should not be too much, and the fertilizer can melt.
5. Insufficient supply of water and fertilizer. In the case of water scarcity, fertilizer uptake is limited. The foliar surface can not absorb the nutrients of the roots, which is the reason for the dry edge of the corn foliage, and the solution can not be in the roots, and the foliar control, with Shi Tianda 2116 and potassium dihydrogen phosphate combined with spraying effect.
6. Long-term planting of a single variety. The long-term planting of a single variety on the plot reduces the plant's ability to prevent diseases, resulting in yellow leaves and dry edges of corn. The most obvious example in our town is the three-year planting of Luodan No. 9 on the same plot, which eventually leads to the occurrence of yellow leaves and dry edge diseases, which affects the yield.
The solution is that the same variety of the same land has been planted for no more than two years, and good results have been obtained.
To keep your living room ventilated, but also to observe whether the tree has been short of water, spray it with a few sterilization potions, and prevent and control it.
In order to prevent the green onion seedlings on the balcony from being slender, it is necessary to avoid too high density under the premise of proper water and fertilizer management, and ensure that the green onion seedlings are lit to the greatest extent.
Planting flowers or vegetable leaves on the balcony at home is caused by dry indoor air, so spray more water on the plants to maintain a certain degree of humidity!
As long as the nutrition is adequate and the sun is sufficient, it can bear fruit. The common problem is that fertility is not enough, or the ventilation is not good, resulting in pests and diseases, resulting in premature death.
Summer is coming, and the strawberries on the balcony must be watered in time.
