What happens if balsam pear fertilizes too much?
Balsam pear should be fertilized with base fertilizer before planting and topdressing after planting, but be careful not to apply too much fertilizer, for excessive fertilization will cause problems. Generally, the root system absorbs fertilizer, and too much fertilizer concentration is too high to be absorbed, and it is also easy to damage the root system. Plant demand will also have a limit, too much fertilizer at a time, can not be absorbed, can only be wasted. Specific fertilizer too much will cause what fertilizer harm, the next will be introduced.
1. Excessive fertilization
If the use of too much potash fertilizer, resulting in fertilizer damage, the main performance is leaf yellowing, death. If you use too much fertilizer at one time, the concentration of the soil solution will increase, causing the cells to lose water, and then they will wither somewhat. In serious cases, they will hurt the roots and die directly. Therefore, the use of fertilizer must ensure that the concentration of soil solution is lower than that of cell solution.
2. Wrong fertilization
Fertilization in the surface layer does not cover the soil absorption is not good, the use of chemical fertilizer can not be buried deep; also can not be too close to the root, the direct use of untreated organic fertilizer, containing a large number of bacteria, insect eggs pollution components; close to the root fertilization; the use of too many trace elements, will resist each other, nitrogen fertilizer too much, will lack calcium, use potassium fertilizer too much, magnesium, boron absorption reduced; direct use of chemical fertilizer, do not add water to dissolve. The above are some wrong examples.
3. Rational fertilization
Balsam pear root system is not very strong, can apply less chemical fertilizer, be sure to add water to dissolve use, use more organic fertilizer, but must be composting, fermentation, later use, the use of organic fertilizer can also be dissolved in the seedling period, the plant can not be dissolved, but only fertilized and watered to help absorption. Fertilization should be matched with a large number of elements, trace elements, the use of the most lack of several, you can sample and test the soil, and then fertilize. Fertilization must be evenly used, mixed comprehensively, can not be concentrated in one place, is not conducive to absorption.
4. Fertilizer application amount
Balsam pear general growth period, a mu of 10 urea, 4 jin of potash fertilizer, 10 jin of potassium dihydrogen phosphate. About 1000 kilograms of balsam pear are required to wash their hands with nearly 12 jin of nitrogen fertilizer, topdressing 2 to 3 times, and applying 20 jin of compound fertilizer at a time. Foliar topdressing, 0.2% potassium dihydrogen phosphate, sprayed 2 to 3 times. Probably fertilize so that it is OK, do not use too much.
Balsam pear fertilization is best not to use more than the concentration of soil solution fertilizer concentration, less chemical fertilizer, more organic fertilizer, it is best to ensure that fertilization is not excessive.
