I've been seeing a lot of friends in the south lately when it's most appropriate to start asking for potatoes
I feel like i need to talk to you here。
Potatoes, as the highest-heated vegetable, have been occupying the half-far river mountain at the table
It's good to feed, and it's high. The stew, the stew, it smells good。
But a lot of people grow potatoes. They always step on pits. Others grow, they follow, they don't look at time。
In the end, there was either a lack of seedlings, or all of them were small marbles, with no production。
Growing potatoes is not the key, it's the golden time. Potatoes are cold and hot, they're not hot, and they're still busy. Today, you have been able to organize a perfect schedule for national potato cultivation, both in the south and in the north。
The minimum temperature of potato hair buds is 5°c and the temperature of the ground suitable for sowing is 10-12°c. A thermometer is inserted into the ground at a depth of 5 cm and the temperature is stabilized within this range for three days, so that seeding can be prepared. It's not too late for early spring, or it's too late for bad seed; it's not too late to miss the long-term and small potatoes. Cultivation can also affect time, with membranes covering 10-15 days ahead of the field. Growing in large sheds is theoretically possible throughout the year, and the key is to control the temperature differentials of day and night. In this context, ordinary home thermometers are sufficient, and there is no need to purchase specialized agricultural equipment to save money。
The point is: this is a national subregional planting schedule, which is recommended for collection。
North-east, north-west and north-west china。
It's cold, it's short, it's only one season a year, and it's a direct decision. Heilongjiang and jilinland experienced a slow recovery, with the best planting time between mid-april and early may, that is, before and after the clear rains, the surface was frozen more than 10 cm before planting. Inner mongolia, north of hebei, can do it sooner than before mid-april. Remember last year's visit to relatives ' homes in the northeast who had grown them after the rain, saying that the potatoes that had been planted at that time were not easily affected by early frost。
Watch out, friends of the north! The sun must be sprouts for the first 20 days。
You have to make the right choice. For eggs, smooth skin, full-eyed detoxification potatoes are the best。
Netherlands no. 15, knew 1, which are particularly suitable for the north。
Cuts are also sophisticated. One or two buds each. Do not forget to disinfect it and bubble it with potassium permanganate solution. Without potassium permanganate? It's an old-fashioned, home-to-face approach to the village
Sliced chips, covered in dry grassy ash. It's good in the stove. It's wet, it's bad for potatoes。
After a day of drying and sowing, the seed rate doubles
Cultivation is used. 60 centimetres in line, 25 centimetres in length. 4000 to 4,500 saplings per acre, exactly. It's too tight to take nutrients, but it's not good. Also, it's 15 centimetres tall enough to make it easier。
The two districts of nakahara, shandong, henan, anhui, jiangsu, are in this range。
The climate is mild and can grow for two seasons a year, with the core being spring and autumn。
The spring broadcast was ready to start in mid-february and early march, and the shock was right. Covered with membranes, it can be planted in early february, so that it can be harvested before the summer heat comes, so that the heat does not affect the growth of the chips。
Autumn broadcasts must be completed in mid-august and within 10 days of the fall. It's too late to grow, and it's not enough to be born, and it's too late to live with the frost. A lot of people like to grow spinach in the middle of the country. Seeds, spinachs can be collected when potatoes come out, without any waste of land。
It is important for central chinese friends to be aware that, in spring, pre-cooked varieties, such as fiuri, will be available for 60-70 days of childbirth, and that small potatoes will be available at the end of may. Autumn seedings must first be processed, with 5 ppm permacin impregnated in order to break the hibernation for 10 minutes or be buried in the soil. Henan autumn has to be protected from aphids, so that 10% of aphids are sprayed once a week. If the rain comes upon the shandong and anhui, remember to raise the stairwell and drain it, and not to let the potatoes rot. It's not expensive to buy cactin at a farm store. A small bottle of water, if not, can soak potatoes with warm water. 24 hours, it almost worked。
Southern winter zone. Guangdong, guangxi, fujian, hainan and yunnan south are all in this range。
It's not cold in the winter, but it's available in autumn and winter fields. Two or even three seasons are fine。
The core is one: avoid high-temperature potatoes. Or the chips don't grow。
The best time for the fall is from late august to early september. The daily temperature drops to below 25°c, and then you do it。
Choosing the fauret, fighting heat! It'll be harvested in early december, with 8 to 10 potatoes。
Winter is between december and january. Remember to cover the membrane with a minimum temperature below 0°c. In the next february and april, we'll have potatoes。
It's a counter-season planting
There are other things that farmers in the south can grow: chili on the edges. After the potatoes are collected, the peppers are just in their prime. The land is not wasted, and the pests and diseases of the two crops can circumvent each other. It's too practical to write down
The southern friends are aware that it is necessary to use fresh potatoes for the spring season. The hibernation of the old potato is not broken, and it is easy to grow。
In addition, during the rainy season in the south, planting takes place at a height of 30 cm or more and drains are 40 cm wide to prevent the accumulation of water at its roots. It is also good to plant a layer of straw that will both keep the temperature cool and improve the soil, followed by stronger potatoes. It's possible to mix rice or wheat, or if not, replace it with a broken leaf, which is more or less effective。
Sichuan, chongqing, yunnan, guizhou all belong to the southwest mixed area。
The terrain is complex, the climate is highly variable vertically and the planting time is particularly flexible. The sichuan basin was broadcast in february-march, often with heavy rains, and also with drainage. Yunnan was both spring and autumn, planting in late march and early april, and reaping in july and august. There's a lot of hot day and night, and the potatoes are growing sweet and noodles。
You can adjust to local altitude and climate, and the core is still warm. In the south-west of the country, many people grow potatoes in the terraces, which are both water and fat, and the potatoes in the terraces are better sensibly smooth than flat ground。
Low-cost, high-yielding techniques, with an additional 30 per cent of production。
The first move, peasant。
They grow up to 15 centimeters, so they're 10 centimeters. Now, let's do it again。
Don't move! It's so toxic to make the chips green. It also leaves room for potatoes and potatoes to grow better。
Second move, choke the bud。
Potato blooms with special nutrients. When you see ray, you're going to cut it off, and you're going to feed all the chips
Third move, manure management。
Potato likes to eat potassium, and remember that. A little nitrogen fattening in the front period, so the leaves grow. It's important to control potassium nitrogen in the later stages。
The tubing period, approximately 40 days after the seeding, is 20 pounds per acre of potassium compound fat. A further 0. 3 per cent of potassium phosphate is used to spray leaves。
The largest amount of water is required during the tubing period, 10 days after flowering. But without water, the soil “wet or sticky hands” would be perfect。
There's a little trick in leaf-spray fat: morning or evening. When the sun is high, it evaporates
Focus: cultivated areas prone to error
Don't use the vegetable market for potatoes as a seed, which could be a fungus, with no guaranteed yield。
Don't be shallow. It's 8 to 12 centimeters deep, and it's easy for the chips to come out green。
Don't fertilize。
Don't wait till the leaves are all yellow! The lower leaves start to turn yellow, they can be collected. Potatoes at this time are of the best quality, and they can be stored。
