In the village of Yangnongjia in Yangjiazhuang Township, Dingzhou City, Hebei Province, Xiaonong Cainmui is known as the "potato king." In 2013, when the potato market was sluggish, he still obtained more than 9,000 yuan in the benefits of potatoes. How did he do it?
One is the selection of a good variety he chose the "Netherlands fifteen" potatoes.
The second is to do a good seed treatment after the seed cutting, with the beneficial micro-bacterial agent 20 grams, èŽ ç¦ ç¦ Fu Mei double 25 ml and Gao Qiao 20 ml, the three mixed with 1 kilogram of water, sprayed with a watering can, block, spray while turning, To make the seed dressing uniform, 1 kilogram of liquid can spray 50-75 kilograms of potatoes. Then put the potato seeds in the cool place for 3-4 days so that the liquid can be fully absorbed and then sowed.
The third is the combination of soil preparation and planting. Deep plowing applies 8-10 cubic meters of fully-fermented cattle manure and 75-100 kilograms of compound fertilizer per acre. Fine ridges are made, ridge height is about 30 centimeters, ridge distance is 60 centimeters, and ridges cover 90 centimeters. The mulch, and then use the earth finder to take soil acupuncture points, on-demand cover soil, on-demand depth of about 15 cm, about 3400 acres sowing, sowing time before and after convulsions, after thawing.
Fourth, do a good job in field management potatoes sow after sowing generally grow 2-4 seedlings, leaving only one strong seed per hole. Under normal circumstances, potatoes need to be watered 2-3 times during the whole growth period, respectively, after the seedlings are flushed out, the potatoes are inflated and before the harvest. When watering, the amount of water should not be too large, and the water can occupy 1/3 of the ditch depth. Apply 50 kg of ammonium bicarbonate per acre and 1 kg of potassium dihydrogen phosphate per acre.
During the period of potato enlargement, regularly expose the exposed potatoes with soil or use weeds to tightly cover exposed potatoes. Control of potato is a necessary measure to obtain high yields. It can be sprayed evenly before and during flowering, using paclobutrazol solution evenly throughout the field, and cannot be re-sprayed or missed.
Fifth, prevention and control of pests and potatoes After soil dressing, there is basically no harm from underground pests. The main diseases of potatoes are late blight, early blight and viral diseases. Late blight can be controlled by propamocarb, metalaxyl and other agents; early blight can be controlled by procymidone, iprodione, and other agents; viral diseases can be controlled by drugs such as Ningnanmycin and mushroom proteoglycans.
