When will the potato (potato) be in control? How to control prosperity?

With the gradual rise of temperature and the invasion of Rain Water, the open-air potato has reached a peak period of growth, which is also the key period to control the prosperity of potatoes. If the potato is not controlled in time, it will lead to the excessive growth of stems and leaves and reduce the yield. when will the potato (potato) grow well? How to control prosperity?

The benefits of controlling prosperity of potatoes (potatoes)

Timely growth control can effectively control the growth of the aboveground part, let nutrients transport to the underground part to promote the rapid expansion of potato roots, in order to achieve the purpose of increasing yield and early maturity, and controlling prosperity can increase the yield of potato by 30-40%.

When will the potato (potato) be in control?

The best time to control prosperity is when the above ground part of the potato has just closed the ridge, there are sporadic buds or blooming flowers. It can't be premature or postponed. Too early, the stems and leaves of the aboveground parts have not yet reached the organic matter produced by photosynthesis needed for high yield, and not enough organic matter has been accumulated in the plant; too late, the aboveground part tends to flourish and consume excessive photosynthates. the ability to supply nutrients to the underground part weakened, resulting in a reduction in yield.

Technology of Potato (Potato) controlling growth

At present, the prosperity control technology popularized in production can be said to be multifarious, and there are at least more than a dozen methods. among these many prosperity control technologies, only a small part of them have been verified by production practice and are welcomed by farmers because of their speed, effectiveness and non-rebound. some technology control boom time is too long, see the effect is slow, the ground part is easy to rebound, resulting in secondary prosperity. Therefore, when controlling the growth of potatoes, we must take stable, accurate and ruthless measures to control the growth, not to control it blindly, but to control it and expand it at one time. The production practice proved that: first, the potato flowers were removed and the reproductive growth was inhibited, and then the foliar spraying effect of "triazole + amino acid foliar fertilizer" was the best. Because potato is a fast-growing crop in North China, the yield formation time is only 10-15 days. If effective measures can not be taken to control the growth in time before the yield is formed, it is inevitable that potato production will be reduced.

Potato (potato) the best medicine to control prosperity.

The use of foliar fertilizer is the key to controlling the growth of potatoes. The foliar fertilizers with growth control effect on the market are paclobutrazol, uniconazole, methylpiperonium, dilatonin and other products, how do we choose?

For paclobutrazol, the effect of controlling growth is good, but because there are residues in the soil, it has a great impact on the following crops, especially the residue of paclobutrazol is greater, so it is not recommended to use paclobutrazol on potatoes. Uniconazole is a broad-spectrum and efficient plant growth regulator, which has both bactericidal and herbicidal effects, and is an inhibitor of gibberellin synthesis, and its activity is 6-10 times higher than that of paclobutrazol, but its residue in soil is only 1 / 10 of paclobutrazol. So uniconazole is a good growth control agent for potato. Methylpiperonium is a new type of plant growth regulator, which has a good internal absorption and conduction effect on plants, inhibit the crazy growth of stems and leaves, control lateral branches, shape the ideal plant type, improve the number and vitality of roots, increase fruit weight and improve fruit quality. For inflatant, farmers should choose brands that are qualified, reliable and guaranteed. Improper use of dilatonin will not only not increase production, but also lead to the decline of potato quality, and even cause fruit cracking and loss of commodity value.
