Potatoes, also known as potatoes, are highly nutritious and versatile to eat, and are loved by people at the table. Potatoes can be eaten as both vegetables and grains, China is the world's largest potato grower, and the total output of potatoes ranks first in the world.
As the old saying goes, "whether there is a harvest or not is in the water, and the harvest is in the fertilizer", in order to ensure a bumper and stable yield of potatoes, scientific fertilization is an indispensable work. So what fertilizer do potatoes like?We can choose these 3 kinds of fertilizers at will, and the potatoes are large and have high yields.
Planting potatoes is inseparable from farmhouse fertilizer, although the nutrient content of farmhouse fertilizer is low compared with chemical fertilizer, but the nutrients of farmhouse fertilizer are complete, and a variety of nutrients can be added to potato plants at the same time, which can effectively prevent the occurrence of "deficiency of nutrients", such as when the potato plant is deficient in iron, the new leaves will lose green, the mesophyll between the leaf veins will turn yellow when magnesium is deficient, and the leaves will become smaller and shrink when there is zinc deficiencySecondly, farmhouse fertilizer has the effect of improving the soil, the soil will become more loose and breathable, and the ability of the soil to retain water and fertilizer will be greatly improved, which is conducive to the full expansion of potato tubersFarmyard manure also activates beneficial microorganisms in the soil, which reduces the growth of pests and diseases.
Another important point is that the potatoes grown with farmyard manure will taste better, and the potato content will be significantly increased.
So which is the best kind of farmyard fertilizer to grow potatoes?As the old saying goes, "pig manure, sheep manure, cow manure follow", the better farm manure for planting potatoes is pig manure and sheep manure, these two kinds of manure have good nutrient content, and the effect of improving the soil is obvious;Cow dung is not only low in nutrients, but also a kind of cold fertilizer, and the organic matter decomposes very slowly after cow dung is applied to the soil, which can not meet the nutrient needs of potatoes, so it is not suitable to use cow dung to grow potatoes.
In addition, we should not apply chicken manure when planting potatoes, although the organic matter content of chicken manure is very high, but if the chicken manure is not fully decomposed, it is easy to lead to the breeding of underground pests, and potatoes are easy to grow insect eyes.
As the old saying goes, "A handful of ashes from a potato plant, and the potatoes form piles", and the "ash" here refers to the ashes of plants and trees. When we plant potatoes, we first cut the potatoes into 30 50 grams of seed pieces, and then sow the seeds after we mix them with plant ash, which can effectively prevent the seed potatoes from rotting.
In addition, when we plant potatoes, we can sprinkle a handful of plant ash next to each seed block, which can increase the income of potatoes by more than 20%. So what is the magical effect of plant ash?
Potato is a potassium-loving crop, and plant ash is not only rich in potassium, but also contains calcium, iron, zinc, magnesium and other minerals, to potato grass ash can effectively improve the plant's resistance to stress;Secondly, the effect of grass ash loosening soil is very good, and potatoes like to grow in soil with large porosity, and the loose soil is conducive to the full expansion of potatoes, and planting with plant ash can fully maximize the yield increase potential of potatoesIn addition, plant ash has the effect of sterilization and insect inhibition, and planting potatoes with plant ash can effectively control pests and diseases, and potatoes will grow smoother.
The growth of potatoes is inseparable from nitrogen, phosphorus and potassium, which can promote the development of stems and leaves, phosphorus can promote the development of plant roots, and potassium can promote the synthesis and transportation of starch, sugar and protein by plants.
Potash fertilizer is the fertilizer that has the greatest impact on potato yield, when the potato enters the flowering stage, the underground tubers of the potato begin to expand, at this time we can apply 25 kg of potassium sulfate per mu to the potato plant, and the yield of the potato will be significantly improved.
1. Avoid applying unrotted farm fertilizer
When we apply farmhouse fertilizer to potatoes, we must fully rot before applying, and the unrotted farmhouse fertilizer will continue to ferment when applied to the soil, which can easily cause the plant to burn its rootsIn addition, uncooked farmyard manure contains a large number of pathogens and insect eggs, and direct application can easily lead to potato diseases and insect pests.
Farmhouse fertilizer should be fermented at least 2 months in advance when applied, and the moisture content of the material should be kept at about 65% during fermentation, that is, the hand is kneaded into a ball and the hand is loosely spread as the standard, and we should turn the pile 1 2 times during fermentation to prevent the pile from burning during fermentation.
2. Avoid partial application of nitrogen fertilizer
When we plant potatoes, we should avoid applying too much nitrogen fertilizer, too much nitrogen fertilizer can easily lead to the vigorous growth of potato plants, and the potato plants will only grow stems and leaves without tubing after they grow.
After the potato seedlings are full, if the seedlings are weak, then we can apply 5 7 kg of nitrogen fertilizer per mu to promote the vigorous growth of the seedlings.
3. Avoid applying chlorine fertilizer
Potatoes, like sweet potatoes and taro, are chlorine-resistant crops, so we should not apply ammonium chloride, potassium chloride or chlorine-containing compound fertilizers when fertilizing potatoes.
This is due to the excessive amount of chloride ions in the soil, which not only easily affects the synthesis of photosynthetic products of plants, but also reduces the stress resistance of potato plants, and the risk of disease of potato plants will increase.
In summary, potatoes like three kinds of fertilizer, namely rotted farm fertilizer, plant ash and potassium sulfate, in the fertilization do not apply unrotted farm fertilizer, avoid the application of too much nitrogen fertilizer, avoid the use of chlorine fertilizer, only scientific fertilization we can grow high-quality and high-yield potatoes.
