Can paclobutrazol be used on cabbage as a coring agent?

Paclobutrazol is a plant hormone drug, mainly to control plant growth, but at the same time it is a bactericidal drug, if it is to be used on cabbage, it should be applied scientifically and appropriately, and it is best not to use it.

Paclobutrazol can be used in Chinese cabbage, it is a bactericidal dosage form, and it is more suitable for the prevention and control of soft rot, one of the three major diseases of Chinese cabbage.

Paclobutrazol is mainly used for the shrinkage of cotton, wheat, sorghum, soybean, strawberry, melon, etc., to inhibit vegetative growth and promote reproductive growth.

We grow Chinese cabbage to grow more leaves, and the leaves don't grow. Chinese cabbage is also worthless.

It is best not to use it, it will affect growth.

It is a fast-growing leafy vegetable, which can be sown from March to September, and can be sown in direct seeding, seedling transplanting, and cuttings (too early or too late will be blown to death by a gust of cold wind).

Can it be used on cabbage? Well, this can't be used on this movement cabbage.

In the same growth environment, if you have more cores, the more plant leaves will grow, and the nutrients may be less.

The cores on the market are chemically synthetic, and if used excessively, not only the taste of vegetables is poor, but also will definitely have a negative impact on the human body.

Medicated cabbage is harder and hard to knock, while unmedicated cabbage leaves are looser.

Chinese cabbage coreing agent is mainly composed of nitrogen, phosphorus and potassium fertilizer and zinc-molybdenum-boron element micro-fertilizer and hormones, it is used for Chinese cabbage rosette stage and early root spraying, can speed up its growth rate, increase its compactness, thereby improving the yield of Chinese cabbage, in addition to can also be used for other stems, leaves of vegetables in the late stage of spraying, spraying within a week after obvious effect, can make vegetable stems and leaves strong leaf fertilizer.

The main ingredients of Chinese cabbage filling agent are: urea, potassium dihydrogen phosphate, zinc sulfate, sodium tetraborate, sodium molybdate and other components.

It is edible if there is no residue or the residue is lower than the national standard.

If you accidentally put it on top of the dish, it is better not to eat this dish.

Paclobutrazol is generally not used in potato production. In addition to controlling the growth of aboveground parts of potatoes, paclobutrazol can also inhibit the formation and development of underground stolons, resulting in early potato setting and premature senescence of aerial parts.

Secondly, improper application of paclobutrazol concentration will cause leaf aging, stop the development of growth points, and premature plant senescence, resulting in the reduction of photosynthetic area in the aboveground part and affecting the yield.

Third, as the "agricultural doctor" said, paclobutrazol has a long half-life, and it is easy to affect the crop after application, affecting the seed germination and seedling growth of crops.

Potatoes in the budding stage to the flowering stage, if the growth is vigorous, you can use Jindel sweet potato expansion and yield enhancer, 30-60 ml per mu, 15-30 kg of water, evenly sprayed on the foliage, control the growth of potato stems and leaves, shorten the internode, improve plant shape, increase chlorophyll content, enhance photosynthesis, promote rooting, coordinate the balance of vegetative growth and reproductive growth, and promote the development of potato tubers.

In the ball-setting and hearting period, 100 grams of Chinese cabbage antiseptic hearting agent per mu is sprayed on 30 50 kg of water, which can increase the yield by 15%, and has a good control effect on Chinese cabbage soft rot, black heart disease, dry heartburn, etc.

Chinese cabbage coreing agent is mainly composed of nitrogen, phosphorus and potassium fertilizer and zinc-molybdenum-boron element micro-fertilizer and hormones, it is used for Chinese cabbage rosette stage and early root spraying, can speed up its growth rate, increase its compactness, thereby improving the yield of Chinese cabbage, in addition to can also be used for other stems, leaves of vegetables in the late stage of spraying, spraying within a week after obvious effect, can make vegetable stems and leaves strong leaf fertilizer.

Answer: The whole growth period of Chinese cabbage can be divided into seedling stage, rosette stage, balling stage and harvest stage. After the autumn sowing of Chinese cabbage enters the balling period, due to the decrease in external temperature, the growth of external leaves slows down, the leaves gradually age, and the growth of heart leaves accelerates. Therefore, after Chinese cabbage enters the balling stage, it needs to absorb a large amount of nutrients and water to meet the growth of leaves.

The demand for water and fertilizer is the greatest.

The reason why Chinese cabbage is not hearty.

1) Insufficient water and fertilizer: insufficient water and fertilizer is the main reason why Chinese cabbage is not heartfelt. After Chinese cabbage enters the bulboding stage, the leaf growth is the largest, and it needs to absorb a lot of water and nutrients to meet the growth of the leaves.

If the soil is dry at the balling stage and there is no topdressing in time, it will cause insufficient water and fertilizer, the growth of stems and leaves is small, and the core is very small, or even not hearted.

2) Variety reasons: the planting time of late-maturing varieties is too late, the growth period is not enough, the leaves are too small and too few, and the plant will appear to be not tight or not wrapped.

3) Excessive humidity: once the planting density is too large, once the heavy rainfall and rainy weather are encountered, the leaves block each other, the field is waterlogged for a long time, and the humidity is too large, resulting in the growth of the outer leaves is too vigorous, and the inner heart leaves stop growing or grow slowly.

Article **3 Solution.

1) For plots with arid soil and insufficient water and fertilizer, it is necessary to water in time, and combined with watering, 15 to 20 kg of urea per mu should be applied with water. Ensure the water and fertilizer needs of Chinese cabbage.

2) artificial bunched leaves: Chinese cabbage bunched leaves, also known as bundling vegetables or tied vegetables, it is in the middle and late stages of Chinese cabbage balling, before the arrival of the initial frost period, the outer leaves of Chinese cabbage are picked up with straw or string, and they are tied to the leaf balls 2 3 measures. For farmers with a small planting area, the method of bunching leaves can be adopted to bundle the outer leaves of Chinese cabbage, which can promote the core wrapping and improve the quality of Chinese cabbage.

2) Spraying core-wrapping agent: After the Chinese cabbage enters the heart-wrapping stage, 6 10 grams of 8% amine fresh ester soluble powder + 80 100 grams of 99% potassium dihydrogen phosphate + 50 100 grams of urea can be sprayed evenly with 20 30 kg of water. Spray every 7 10 days, 2 sprays in a row, 3 times.

It can not only quickly replenish foliar nutrients, but also promote the rapid growth of leaves. Promote Chinese cabbage wrapping. Improve the yield and quality of Chinese cabbage.

I'm going to buy some cabbage wrapping agent.
