Attention to the country where the potatoes are grown. To make them big, round and double, the key is that they grow to 30 to 40 centimetres and are about to be closed. This stage is the critical node of potato start-up potatoes, with the following three management points: this year's potato production and quality will definitely take a new step forward。
Number one, remove all buds in time. Potato blooms consume large amounts of nutrients, which could have provided for the expansion of the trachea. When the buds are removed, the nutrients are concentrated in the supply of chips, which are estimated to increase the production of potatoes by more than 10 per cent, and are larger and more even. The operation should be carried out in the morning of the sun and should be carried out in such a way as to prevent the damage to the blades。
The second point is control. If the potatoes grow too much, they compete for nutrients with subsurface chips, resulting in small chips and low yields. When plants reach 40-50 centimetres and bouquets appear, they are the best time to control them. Small-area cultivation can crush flowers and break the top edge; large-scale cultivation can use such pharmaceutical agents as calcium naphthenate, alkyl, etc., with care to dilute them strictly in accordance with instructions to avoid drug harm。
Third, fill in the boron in time. Potato lack of boron can lead to small sizes of chips, vulnerability to cracks and deformities, which seriously affect quality and productivity. Following the potato sealing, foliage is sprayed with 30 kg of water plus 30 g of potassium phosphate and 15 ml of fluent boron, once every 10-15 days and three times in a row. This is a quick supplement to boron, contributing to the expansion and quality of the chips。
Under this method, potatoes are not only large and good, but can also increase production significantly. This is the critical period of potato management. Let's get moving. This year's potato harvest depends on this wave
