What should I pay attention to when capsicum is deficient?

1. Symptoms of capsicum deficiency.

1. Nitrogen deficiency: the plant is thin, the leaves are small and thin, yellow, and the leaves fall off in the later stage.

2. Phosphorus deficiency: the seedling stage is slow to develop, the plant is thin and small, the adult plant is deficient in phosphorus, the leaves are dark green, the leaf tips turn black or die, stagnate growth, and the leaves begin to fall from the lower part, and do not bear fruit.

3. Potassium deficiency: symptoms appear during the flowering period, the plant grows slowly, the leaf edge turns yellow, and the leaves are easy to fall off. Potassium deficiency at the adult stage, the tips of the lower leaves turn yellow, yellow pockmarks are formed along the leaf margins or between the leaf veins, and the leaf margins gradually dry up, expanding inward to the whole leaf in a burning or necrotic state; The leaves develop from the old leaves to the heart, and the leaves develop from the tip of the leaves to the petioles, and the plants are prone to water loss and wilting, and the fruits are small and easy to fall.

4. Calcium deficiency: lack of calcium in the flowering period, the plant is short, the parietal leaves are yellowed, the lower part remains green, the growth point and its vicinity die or stop growing, and the lower part of the fruit turns brown and rots; In the later stage, there is a lack of calcium, the leaves have yellowish-white round spots, the edges are brown, the leaves fall off from top to bottom, and the whole plant is bare-roded in the later stage, and the fruits are small and yellow, producing umbilical rot fruit.

5. Sulfur deficiency: the plant grows slowly, has many branches, the stem is hard and lignified, the leaves are yellow-green and stiff, and there is little or no fruit.

6. Zinc deficiency: the plant is short, the top leaflets are clustered, the growth is retarded, the leaves are deformed and small, the leaves are curled and wriveled, there are browning spots, the top withering occurs, and the leaves are yellowed or fallen off within a few days.

Second, the lack of capsaicin **.

1. Organic fertilizer or nitrogen fertilizer is applied before nitrogen deficiency, and the nitrogen content in the soil is low, the rainfall is more, and the nitrogen leaching is more.

2. In the phosphorus deficiency seedling stage, the soil is acidic or compact.

3. Low potassium content or sandy soil in potassium-deficient soil, and potassium fertilizer is needed for fruit expansion in the middle of growth, which is insufficient.

4. Excessive application of nitrogen fertilizer and potassium fertilizer due to calcium deficiency will cause the soil to be dry, the soil solution concentration is high, the air humidity is small, the evaporation is fast, the water replenishment is not timely or the calcium deficiency is on the acidic soil.

5. Sulfur deficiency long-term continuous application of fertilizer without sulfate.

6. Boron-deficient soil acidification, boron leaching or excessive lime application.

7. There is a lot of phosphate fertilizer in iron-deficient soil, and alkali affects the absorption and operation of iron.

3. Prevention and control methods of capsicum deficiency.

1. When there is a lack of nitrogen, apply compost or fully decomposed organic fertilizer, and use formula fertilization. Nitrate nitrogen is more effective. Fertilization is applied according to different periods such as pepper seedling stage, early fruit stage and full fruit stage.

2. Phosphorus fertilizer should be applied during the phosphorus deficiency seedling stage and planting period, phosphorus pentoxide is required in the culture soil, and potassium dihydrogen phosphate or superphosphate can also be sprayed on the foliar surface.

3. Potassium deficiency on the basis of more organic fertilizer, apply enough potassium fertilizer, can be furrow application of potassium sulfate, plant ash, soil covering, can also be foliar spraying potassium dihydrogen phosphate.

4. Apply an appropriate amount of lime for calcium deficiency, spray water-soluble calcium on the foliar surface once every 3 4 days in case of emergency, and apply plant growth regulator (brassinolide).

5. When there is a lack of sulfur, apply sulfur-containing fertilizers such as ammonium sulfate.

6. Boron deficiency foliar spraying borax aqueous solution.

7. Zinc-deficient soil can not be over-applied with phosphorus, and foliar zinc sulfate aqueous solution should be sprayed.

Capsicum deficiency should be paid attention to, drain the chili pepper in the sun, don't let the chili pepper find water, it will drown if it takes too long.

People are sometimes uncomfortable. Well, please refrain from eating chili peppers. Or, if you can, don't eat it.

Chili peppers are very tasty, everyone loves the taste of chili peppers, and the nutritional value of chili peppers is very rich.

Although it didn't satisfy you, I still tried my best, and if mine is helpful to you, please click Very Satisfied.

Pepper growth period is long, the amount of fertilizer is large, the fertilizer tolerance is strong, but because its root system is not developed, the amount of roots is small, the soil is shallow, a little careless, it is easy to occur capsicum deficiency phenomenon, farmers timely find and prevent the occurrence of nutrient deficiency, do a good job in strengthening fertilizer and water management, pepper root-knot nematode disease should also be paid attention to. In recent years, with the continuous expansion of vegetable planting area, especially the development of facility greenhouses, the phenomenon of heavy stubble planting is common, which aggravates the degree of nematode, especially the root-knot nematode, which has become the main factor affecting the planting and production of pepper. It is recommended that farmers use Yinghui threadicide granules to apply in furrows, holes or whole fields before transplanting peppers, and the duration is as long as 2-3 months.

If the pepper is harmed by root-knot nematode disease during the growth period, it can be irrigated with water and flushed with the blue root sand in the Yinghui killing line.

What should that family pay attention to? You can take a look at the book on plants, and you can also ask a plant expert.

It is impossible to lack any tree of peppers, if the peppers themselves are vegetarian, it must be that the seeds of the peppers are not good, or the peppers have produced diseases in the process of planting, so if the peppers are planted normally, they will not lack peppers far away.

First of all, let's understand the causes of capsicum deficiency, according to the phenomenon of deficiency in the past two years, the aboveground plants often have the symptoms of weak growth, abnormal yellowing of leaf color, dwarf, and many nodules of different sizes and shapes grow on the lateral roots and fibrous roots in the underground roots, and the root knots are milky white and solid at the beginning, and then gradually turn black-brown, and there is the phenomenon of decay.

According to experts, capsaicin deficiency is due to the damage caused by root-knot nematodes. The root-knot nematode of pepper invades the young tip of the new root with the instar larvae, invades the root, develops with the growth of the root, absorbs nutrients in the root of the pepper, forms giant cells in the affected part, and a large number of tissue necrosis in the phloem, swells the xylem, and blocks the duct. If the reed cannot be absorbed and transported to the root system for a long time, only nutrients will be used, and some parts of the root will rot.

Experts also said that in addition to the nutrient deficiency caused by the harm of root-knot nematodes themselves, the mechanical damage caused by their puncture of the root system during infection may also facilitate the invasion of other diseases. The investigation found that in the fields with serious damage from root-knot nematodes, capsicum deficiency disease often occurred, which harmed together with root-knot nematodes and aggravated the disease. So, what is the simple and thorough treatment of root-knot nematode?

In view of the incomplete control of pepper root-knot nematodes, experts suggest that farmers need to use pesticides to achieve the effect of controlling the number of nematodes in the soil. In the selection of agents, experts recommend farmers to choose Yinghui threadicide. If the pepper is harmed by root-knot nematode during the growth period, irrigating the roots with Yinghui nematode water and flushing can have a good control effect.

Judging from the current feedback from users, after the use of Yinghui threadicide, the root system of pepper is developed, there are many new white roots, and the disease resistance is improved, which completely eliminates the lack of capsaicin.

1.When potassium is deficient, on the basis of more organic fertilizer, apply enough potassium fertilizer, you can apply sulfuric acid such as potassium and grass ash from both sides of the ditch, cover the soil after application, or spray 0 2% 0 3% potassium dihydrogen phosphate or 1% plant ash leaching solution on the foliar surface.

2.When boron deficiency, the foliar spray 0 1% 0 2% borax aqueous solution is 1 time every 5 7 days, a total of 2 3 times.

3.In case of iron deficiency, 0 5% 1% ferrous sulfate solution can be sprayed 1 or 2 times;

4.When manganese is deficient, the foliar spray 1% manganese sulfate aqueous solution 1 2 times.

In short, what is lacking in chili peppers, Qi will give it what nutrients to supplement!

It is recommended to check the root system of the plant, if the root system is normal and it is a whole yellowed pepper, it is sulfur deficient. Sulfur is involved in protein synthesis and is called an element of auxiliary life.

Sulfur deficiency leads to the failure of the plant to synthesize protein normally, and the whole plant is uniformly yellowed and dwarfed.

Generally, it is easy to occur in sulfur-deficient soils, such as calcareous soils, arid soils, desert soils and saline-alkali soils in Inner Mongolia. It is recommended to apply 10-15 kg of sulfur or 30-50 kg of gypsum per mu of soil to supplement soil sulfur.
