Last week, the author shared knowledge of the farmer's salon's activities on the foodization of potato owners and the development of staple food products, and this week will continue to share another plate: potato-free farming techniques。
At this sharon event, the farm housekeeper invited mr. Wang yong-chun, who had had the privilege of hearing a lecture from mr. Wang before becoming a big fan of him. Mr. Wang is also said to be popular with a number of farmers on the app platform, as he not only has a solid expertise, but also has a good sense of humor and has often included interesting examples in his lectures, making the course less serious and easy to listen to. By the way, mr. Wang is said to have learned a lot about medicine and has not changed weight for decades. Let's talk to mr. Wang later
1 drumb
The choice of seeding: the quality of seeding determines the production of potatoes, which can account for between 60 and 70 per cent, with no skin, no insect bite, no decomposition, and high-quality detoxification potatoes。
Scrawl and sprouts: 2-3 days sun, 15-20 days pre-sprouts, 15-20 degrees. The length of the sprouts shall be less than 5 cm and 2-3 cm shall be appropriate。
2 cuts
Potato cutting is an important link in the high production of potatoes and in the pest control of potato disease, such as the softness of potatoes and the potential for the transmission of potatoes from the crop。
Small potatoes can be sowed with chips below 40 grams of cut-off method; 51-100 grams of chips with all two petals vertically; 100-150 grams of chips with all three-part slashing cuts, i. E., cutting the chips vertically into three petals; and more than 150 grams of chips, with a number of small pieces of body triangles in the direction of tilting from the tail to the top, depending on the extent of the budding eye, in line with the budding spiral. Cut blocks with the full power of the top, and try to take the top bud. The slices should be cut close to the bud's eye in order to get a lifagen. Each block weighs not less than 25 grams and as much as possible keeps it in the middle。
Care is taken to remove the potatoes, the sick potatoes and the fine potatoes from the slices。
The correct cut-off method helps the potato grow early, saves the seed, and avoids the loss of seed because it increases the spread of the disease and causes the seeding of the chips to rot。
3 blend
The aim of potato blending is to eliminate the pathogens that are carried on the surface of the potato, as well as to reduce the occurrence of endemic pests and diseases, and to promote seedlings and growth. The blending formulations are: 50% of the fungus, or 70% of the atolls mixed with the fossil powder 1:100。
4 total land
Before winter, farmers are fattening and tilling more than 30 centimetres. Potatoes are harvested from underground truncheons, which, in order to promote high yields, must create a good soil environment for their underground growth. Deep cultivation can defusing the soil, improve water storage and conservation capacity, harmonize water, fat, gas, heat and fertility factors in the soil, and provide a comfortable growth environment for the growth of the potato roots and runners and tubers. Thus, deep cultivation is the basis for the high production of potatoes. According to studies by heilongjiang, shanxi and gansu, the pine layer can reach up to 30 centimetres at depths of 15-18 centimetres, with a 10 per cent increase in the production of more shallow farming. Up to 36 cm, 63. 1% more than 18 cm. This can be seen as a prerequisite for high potato production。
5 fertilisation
Potatoes form a large number of leaves and tubers over the long term and therefore require more nutrients. Of the three elements of fertilizer, the highest amount of potassium is required, followed by nitrogen, and the lowest by phosphorus. For example, the levels of potassium nitrogen phosphorus are 14-8-25, a proportion of which can be used as special fat for potatoes. Fertilization can be determined in accordance with the target production. For the production of 5,000 kg of potatoes: potassium nitrogen phosphorus 25, 10 and 50 kg (purified)。
Fabrication plays an important role in increasing potatoes production. Potatoes account for three fifths or two thirds of total fat. Base fat is dominated by fat machines (for pre-drop application), such as rotting compost and human and animal dung; co-opt phosphorus, potassium fat。
6 seeding
Seed density: potato cultivation density: 4,000-5,000 dens/acre. Up and down. The average length of a ditch is 110 centimetres, a double row, 85 centimetres in length and 25 centimetres in length (55 centimetres in average). If the distance is 30 centimetres, the area of nutrition is 0. 55x0. 3 = 0. 165 square metres per acre, approximately: 667/0. 165 = 4,000; if the distance is 25 centimetres, the area of nutrition of 0. 55x0. 25 = 0. 137 square metres per acre is about 667/0137 = 4800。
Machine seeding
Machine sowing effects
After seeding, artificially presses some soil on the membranes to protect them from the wind. Broken
(c) post-scattered soil: in order to prevent low-prevalence, the potato swelling period is exposed outside the soil to affect the quality of the product by starting mechanical soil before the bulging under the membranes, while at the same time reducing the workload of the late artificial defaced membranes. However, care should be taken not to sow the soil immediately after it has been planted, so that the seedling period does not grow。
Mechanical earth cover effect
7 pest management
Potatoes suffer more from diseases, which are common, such as viral diseases, chronic diseases, ailments, cyclic diseases, scabies, cancer and swelling. Late diseases occur before and after periods of heavy rainfall and planting. The drugs used to combat the circulatory plague of potatoes are: green, silver, fast, truffle, gold, venom, plek, cascading, cyanide, fresco, manganese zinc, mescaline, manganese zinc, manganese zinc, ice, manganese zinc, cosmopolitan, ethyl phosphorus, etc. It is more difficult to combat ailments, mainly through rational rotation, selection of resistant varieties and seeding of small whole potatoes。
Night disease
Potato-tape fungus, black scab
Volatile fertilizer burns
Ben's bad first. There's a high risk of not mixing
8 harvest
Most of the leaves are turned green and yellow, and then yellow, and the subterranean tubers are biologically mature and should be harvested immediately。
Kill
The harvest
In fact, there are many techniques to manage the cultivation of potatoes, and the methods of planting and management vary from place to place due to climatic conditions and so on. There are also many management details that are not immediately available owing to the limited level of staff. This is why i am afraid to share it with you。
As mr. Wang's faithful powder, i'd like to recommend to you a few videos of mr. Wang's lecture on potatoes

Ps: the masters of potato growing in every street, and some of the best techniques for crop management, can be shared with farmers in the bottom area. ~ in addition, if there is a problem, it is said that a message can also be left at the bottom。
It focuses on “agricultural housekeepers” and first learns more about more comprehensive agricultural information (reading policies, finding loans, buying farming, learning farming skills, buying and selling products)。
