Studies have shown that 70% of the tuber yield is formed from the period of potato flowering to the senescence of stems and leaves. This period is also the period when the potato needs the most fertilizer and water in a lifetime. The amount of potash fertilizer absorbed by plants is 1.5 times more than that of the growing period, and the amount of nitrogen fertilizer absorbed is one time more than that of the growing period. Fully meeting the potato demand for fertilizer during this period is the key to obtaining a good harvest. It is recommended that vegetable growers timely watering, and apply 25 kg of NPK fertilizer per acre with water, or apply 5 kg of high potassium fertilizer to ensure adequate water and fertilizer supply.
[Go to flower buds]
The flowering buds of potatoes consume a lot of nutrients, so see buds try to pick them up, promote the expansion of the tubers and increase the yield.
[Note earth]
Some of the plant's stolons emanate from the ground, and the tips of the stems turn green, giving rise to green leaves that form new shoots, which can affect the expansion of the tubers and result in reduced yields. After the potato chips turn green, the content of solanine is increased. It not only tastes spicy and numb, and its commerciality is reduced. Nausea, dizziness, and other symptoms of poisoning may also occur. Therefore, soil should be cultivated in time to prevent the above phenomenon from occurring. Potatoes are generally used to cultivate soil twice and the soil thickness is 3 to 4 cm to prevent them from being exposed on the ground.
[control prosperous]
The flowering stage of potato is also the most vigorous stage for the growth of shoots and shoots on the shoot. At this stage, attention should be paid to the control and prolonged growth of potato tubers. Farmers can spray 0.1% of chlormequat according to potato growth to spray best when the plants bloom.
