1. Turn the soil deeply.
Potatoes develop and grow in the soil, and the soil used for planting must be loose and breathable, therefore, before planting, choose a good soil, preferably sandy soil, no sandy soil should also make the soil loose, and rich in organic fertilizer, and then carry out deep turning, and the soil is fine, leveled, which is the basic condition for potatoes to obtain high yield.
2. Choose good breeds.
It is necessary to choose potato varieties suitable for local cultivation according to the needs of the market and local climatic conditions, and also to choose varieties with strong disease resistance, high yield and good quality. When selecting seeds, it is necessary to remove diseased potatoes and bad potatoes, and choose potato chunks with smooth surfaces and full sprout eyes. Before sowing, it is necessary to carry out seed dressing, which can be mixed with pesticides or plant ash, in order to prevent the occurrence of pests and diseases.
3. Sow seeds at the right time.
Due to the influence of climate, potatoes are sown early, rotten seeds, lack of seedlings are serious and easy to old seedlings, sowing late and susceptible to frost hazards, can not mature, suitable for sowing period is short, should be strictly controlled. The sowing date should be adjusted in a timely manner according to local conditions, and the sowing depth should be determined according to the moisture condition. Shallow sowing is susceptible to drought and high temperature, which is not conducive to the growth of plants and the formation and expansion of tubers, affecting yield and quality. And spray a new high-lipid film on the surface of the plant to enhance the fertilizer efficiency, prevent the infection of pathogens, improve the ability to resist natural disasters, improve the efficiency of photosynthesis, and protect the growth of seedlings.
4. Check the seedlings and replenish the seedlings.
After the emergence of potatoes, it is necessary to check the seedlings and replenish the seedlings in time to prevent the lack of seedlings and broken ridges from affecting the yield. When replenishing seedlings, it is necessary to pay attention to the selection of robust seedlings for transplanting, and timely watering and top dressing after transplanting.
5. Cultivating soil.
Soil cultivation is carried out several times during the growth of potatoes in order to loosen the soil, promote root development and tuber formation. Before ridge sealing, the soil should be cultivated for the last time, and potato and potassium fertilizer should be applied once to promote the expansion of the tubers and the accumulation of starch.
6. Fertilization management.
Do not use nitrogen fertilizer alone when planting potatoes, nitrogen, phosphorus and potassium must be reasonably matched, and the ratio of nitrogen, phosphorus and potassium required for potato growth is 1 05∶2.5. It is a potassium-loving crop, in addition, there are calcium, boron, etc. Therefore, when planting potatoes, in addition to the use of organic fertilizer for base fertilizer, it is best to apply high nitrogen and high potassium fertilizer in the tuber formation stage to meet the needs of potato growth.
