The yield of potato can be increased only by topping and blooming at the florescence in time.

Potatoes were used as decorations before the sixteenth century because of their beautiful flowers, and were later discovered by the French as edible, so they spread. Flowering is the most important time for potato growth, because this is when potato tubers (i.e., edible potatoes) begin to accumulate starch and slowly expand.

Below we from potato flowering conventional management and some of the more unusual management of two aspects to introduce you.

Conventional treatment of potato florescence

One is to cultivate soil in the middle, the height of soil cultivation should reach more than 10cm, generally two times of soil cultivation, once in the bud stage, once in the full flowering stage, if more labor can be used once high soil cultivation, soil cultivation is very critical to potato growth, so it cannot be omitted.

The other is water and fertilizer management. Fertilization without proper water management is hooliganism. Watering and timely supplementation of nitrogen, phosphorus and potassium fertilizer have great effects on the growth of potato tubers. Field watering with a small number of times is good, avoid flooding ridge, fertilizer mainly phosphorus and potassium fertilizer, foliar spray, field topdressing can be.

Third, topping and flower removal, potato harvest is potato pieces (stem pieces), timely flower removal can make nutrition more concentrated to tubers, which is helpful to improve yield.

The fourth is pest control. The main pests of potato are aphids, ladybugs and underground pests, which can be controlled by trichlorfon spraying and seed dressing. Diseases are mainly bacterial diseases caused by high temperature and humidity, which can be prevented by copper sulfate.

Special management measures for potato florescence.

One is chemical prevention and control, mainly to prevent potato plants from excessive growth, that is, the so-called only long but not long yield, can use paclobutrazole for prevention and control, can also use chlormequat, uniconazole, etc., happy to use which, as long as not excessive good.

The second is temperature control. This management is only applicable to greenhouse planting. In March or so, the temperature of greenhouse potato can be adjusted to make potato grow at the optimum temperature. The temperature standard is 16-18℃, and the soil temperature standard is 18-21℃. At night, the temperature can be appropriately reduced to facilitate starch accumulation.

The third is to spray potassium permanganate, potassium permanganate has a certain preventive effect on viral diseases.

Potato flowering is an important period to determine yield, water, fertilizer, soil cultivation, disease control, topping can not be less, special management measures can be selected according to growth conditions and environmental conditions, if greenhouse planting, harvest can be advanced to the end of April and early May, can sell a good price, if field planting, harvest in June can obtain higher yield.

The above comes from science and agriculture.
