Plants lack this fertilizer, the leaves turn yellow, and the flowers are sparse!
When planting flowers, I always encounter the problem of yellowing leaves. Every time I see yellow leaves, it gives me a headache. I don’t know where the problem is. Is it too much water or too much sun? In fact, it may also be a lack of fat!
Nitrogen, phosphorus and potassium fertilizers are the most commonly needed nutrients for plants. If any one of them is missing, the plants will show abnormal conditions. Let me explain them in detail!
- Plants lack nitrogen fertilizer
Nitrogen fertilizer is mainly long leaves, lack of nitrogen fertilizer, the growth rate slows down, the leaves become thinner, the color shows abnormal green such as yellow-green, yellow-orange, etc., and the old leaves at the bottom gradually dry and wither, with the serious lack of nitrogen fertilizer, the root system The branching ability is reduced, the plant becomes sparse, and subsequent flowering and fruiting will be affected.
- Plants lack phosphate fertilizer
Phosphorus fertilizer is to induce flowers and fruits. The lack of phosphorus fertilizer shows that only leaves grow without branches, the color of the leaves is dark green or gray-green, the edges of the leaves appear purple, and the leaves are easy to fall off; the flowering period is delayed or does not bloom. Phosphorus deficiency symptoms generally start from the old leaves at the base of the stem and gradually develop upward.
- Plants lack potassium fertilizer
Potassium fertilizer is strong root, lack of potassium fertilizer, old leaves and leaf margins turn yellow, then turn brown, scorched like burning, but the middle of the leaves and the veins are still green; with the intensification of potassium deficiency, the entire leaf becomes Reddish-brown or withered; root system is stunted, resistance becomes poor, easy to rot and lodging.
It seems that NPK fertilizers play a vital role in the growth, flowering and fruiting of plants. In addition to purchasing corresponding chemical fertilizers, we can also make organic NPK fertilizers at home. There are many benefits to eating plants. Save money on buying fat!
- Production of nitrogen fertilizer
Nitrogen fertilizer is mainly supplemented by protein-rich plants, such as soybeans, urine, beer, etc. Find a large plastic bucket, boil the soybeans with water, and after cooling, put the beans and water in a plastic bucket Inside, don't be too full, there are 80% of them, cover the lid, put it in the corner of the balcony, unscrew the bottle cap every 2 days to let out the air, it will take about 2~3 months to ferment, and pour it when you use it. Dispense the clear liquid above, dilute it 10 times with water, and water the growing plants every two weeks.
The fermentation method of beer and urine is the same. If you are afraid of too much taste, you can add more orange peel or lemon; pay attention to environmental hygiene when using it in the city.
- The production of phosphate fertilizer
Phosphate fertilizers are mainly used to induce flowers. The most commonly used phosphate fertilizers are bone meal and fish intestine fertilizer. Bone meal is more troublesome to make, and most of the bones contain salt. You might as well buy ready-made ones. Fish intestine fat can be made by yourself.
In winter, go to the vegetable market to ask the boss for some fish intestines, take them home and find a big bucket to pack them, and then pour in clean water or rice-cleaning water for fermentation. And a lot of citrus peels come and go, put it in the corner of the yard or on the balcony, and it will ferment in about 3 months.
When using it, it also needs to be diluted, about 10 to 20 times. During the flower bud differentiation stage of the plant, water it every 10 days.
- Production of potash fertilizer
Plant ash is the most commonly used potash fertilizer, but its pH value is alkaline, and only a little is used at a time. Plant ash can be made by burning fallen leaves. Usually sprinkle a little on the surface of the pot, which has the effect of sterilization and insect prevention; Plant ash on the surface can improve the cold resistance of the plant and prevent frostbite of the root system.
In addition, watermelon peel and fragrant peel are also potash fertilizers, which are fermented with rice-washing water mixed with peels and broken eggshells; banana peels can also be dried in a microwave oven, sterilized at high temperature, and then buried in the soil as a base fertilizer for plants.
