Potato (academic name: ipomoea batatas (l.) lam). One year of grassland。
The subterranean part is of a round, elliptical or hammered root, with a pedal or an elevation, with an occasional entanglement, with multiple branches, with leaves in different shapes and colours, usually wide ovulations, different lengths of leaves, fusion of umbrellas, pore or flat-shaped, seeds of one to four, usually two, without hair。
Potato is produced in south america and in the greater and lesser antilles, with widespread cultivation in tropical and subtropical areas around the world and in most parts of china. Potatoes are a highly productive and adaptable food crop that is closely linked to industrial and agricultural production and people's lives. In addition to being the main source of food for eradication, it is an important raw material for the food processing, starch and alcohol manufacturing industries, with roots, tubs and leaves being excellent feed。
Morphological characteristics: a year-old grasspad with a circular, elliptical or hammer-shaped root in the subterranean part, the shape of the root, the skin colour and the skin colour vary from species to soil. And he lays down or rises, entangled, branched, cylindrical or lurking, green or purple, fluffed or hairless, and leaves his penis unsettled。
Varieties vary according to species and growth conditions, with some species being easy to bloom, others bloom in times of drought, often in areas with high temperatures and short daylight, and rarely in areas with lower temperatures. Pyramid ovaries or flat circles with false diaphragms divided into four rooms. Seeds 1-4, usually 2 without hair. Since potatoes are pollinating with algae, self-plowing is often weak, and sometimes the result is invisible。
Potato cultivation
Fertilization of the earth: the earth shall run in the middle of the sun, and the earth shall be broken and detailed. When it is leveled, the fertilizer bars are applied to the bottom at a distance of 80 centimetres and 20 centimetres. Fertilizers can use specialized organic compound fertilizers, which require soil n, p, k and organics to be measured when the area under cultivation is large, and soil ph in the south. The use of common compound fertilizers is not promoted。
The whole branch is to be hit: it can cut off two or three branches with scissors for larger and more growing potato fields, so that nutrients can flow back and the chips can get more nutrients. The ceiling regulates the functioning of nutrients and facilitates their transmission to the root. When the seedlings grow to 40-60 centimetres, they are taken away when the branches thrive。
Timely pursuit of fertilizers: the fattening of seedlings follows thin human and animal dung from 750 to 1,000 kg or urea from the first ploughing of 667 m2 approximately 15 days after the insertion. Potato fertilizers are followed up during the cleavage phase and are usually combined with second medium-cropping in the month following the insertion, mainly with nitrogen fertilizers and with potassium phosphate。
After the leaf is sealed, the roots grow faster and fatten when the ground cracks. For every 667 m2 urea chase 1. 5 kg, percinium phosphate 10kg leachate, potassium sulphate 3kg vs. Water 150-200kg nutrient, sewn in the middle of the day or in the middle of the day, requiring even pursuit of fat。
Storage: the harvest of pre-maturized early varieties began at the end of august and early september, and the harvest of late-finished varieties began in mid-october. The harvest is before the frost. Rainfall harvest is prohibited. The harvest is made with light digging, light dressing, light transport, light discharge, and protection against scratches on the peels and chips. Storage requires temperatures of 10-15°c and relative humidity of the air of 85-90°c, and storage sites should be kept clean and free of rat and poison. At the same time, measures should be taken to protect against freezing and crushing and to ensure ventilation and heat spread。
Diy small plant: potato plant can be watered or grown with soil. Before planting a red potato pelvis, all raw materials are prepared and a beautiful flower pot or vase is selected for the market. If you want to water the potatoes, you have to choose a vase, which is about 15 centimetres high, and not too big to open。
If you want to plant a potato pot with dirt, you have to buy a wide-cut flower pot of the right size and prepare some dirt. Potatoes are less demanding for soil and can generally be trusted with loose, air-transmitting sandy soils. When you've got a vase or a flower pot, you'll have potatoes。
In the case of water-fed potato pellets, it is possible to select from the market some of the fine-looking, long-sized sweet potatoes, so that they can be kept in a vase and be more beautiful. If the soil is planted with a potato pot, it is not too demanding。
(b) water for the potato plant: wash the potatoes in the water, fill the vase with about half a bottle of water, then place the wash of the potatoes in the vase, so that half of the potatoes are immersed in the water, the other half in the air, waiting for the seeding of the seed. In about four to five days, the seedlings will grow slowly, at which point the water-fed cassava plant will basically form。
In about two to three weeks, the growing size of the potato seedlings and the growing cassava can be trimmed in the shape of the cassava, and a beautiful cassava plant can be planted. Put it in the house, look at the green leaves, and it's alive。
It is often replaced by a regular one-to-two-week change of water, with less water, which would otherwise easily decomposition. If the cassava rots, the rotting part can be cut off, and if it rots more, a whole cassava plant may be lost and replanted。
Cultivation of the potato pellets with soil: the soil ploughing of the potato pellets is roughly the same as that of water. However, soil can grow a potato pot, either by cutting it up to a few pieces, or by planting a whole small potato in a flower pot, with two to three red chips in a flower pot at the same time, so that it can grow thicker。
After planting the sweet potatoes, water is poured into the flower pot and placed in the cold, where the sun comes in, waiting for the sweet potatoes to sprouts. About a few days later, it grew. They then regularly water the potatoes, keep the soil wet, tan the potatoes in the sun, give them enough light, grow the cassava pots well, and when they grow, the cassavas are beautiful。
