It's a design for you, the long triangle direct planting technique. In response to your location in shanghai and the surrounding areas (central and downstream alluvial plains of the yangtze river, wet climate, short autumn season, heavy rain before winter), i have prepared a technical manual on vegetables that can be grown directly from the end of august to november。
The manual does not contain seedlings, but focuses on the direct planting of seeds in open ditches or caves, and focuses on three core pains in shanghai during autumn: plumbing, seeding and pre-winter resistance。
Chapter i: bottom logic and golden window for direct sowing in shanghai fall
Autumn tigers (high temperature and humidity) in september, high-temperature but dry in october, sharply cooled in november and accompanied by cold tides. The success or failure of direct seeding depends on a race between the “sapling speed” and the “temperature speed”。
Chapter ii: operational techniques for direct planting of four categories of autumn vegetables
All seedlings are subject to an iron bar “deeply fine, dusty and dusty” with regard to the adhesiveness of the soil in the long triangle. If the clay is large, the seeds will be emptied and not absorbed。
Category i: vegetables (cigarettes, oatmeal, trachea, spinach, cocoon)
This is the absolute backbone of the fall seeding, which is cold-resistant and can be picked continuously from november to december。
** on behalf of the vegetable species: shanghai cyanide (chicket), spinach
(b) tunneling: shanghai has more rain in the autumn and, in order to avoid bad root, it is recommended to plant high tungsten. The face is 1 metre wide and the ditch is 20 cm deep. Three days before seeding, 25 cm deep, tanned and then applied fully fertilized organic fertilizers (sheep dung or earthworm dung, taboo) to each acre. Drum treatment (for high-temperature season): spinach: direct seeding in shanghai in september was extremely difficult to germinate (spread down over 25°c). “crust impregnation” must be performed: seeds must be squeezed lightly with bricks or hard matter (to split the skin), immersed in cool water for 12 hours, leached and humid clothed for 24 hours in the freezer room (about 5°c) to be rebreeded in small white roots. Pillards/shells: small seed, no need to sprouts, but high temperature hibernation. Before seeding, the face is poured through the bottom water, so that it can see through the water before seeding, and then covering 0. 5 cm thick dry soil. Seeding techniques: sowing (leaves) or stripping (springs). The seeds were mixed into 10 times the fine sand and distributed in two parts, in order to achieve parity. Cover thickness iron: three times the diameter of the seed. The raw seed is small and requires only a thin layer of sifting soil; the spinach must cover 1-2 cm. Repression and coverage: seeding with a small hand or wooden plate has brought seeds into close contact with the soil. High-temperature and strong light in shanghai in september must be sowed, covered with sunnets or straw, wet and shaded, and removed immediately after seeding. Category ii: roots (white carrots, carrots, cherry carrots)
Such vegetables are the most vulnerable to displacement and must be broadcast live. In the long triangle, autumn is the best season for carrots。
The whole ground requirement - deep to life: cabbage and roots can be as deep as 30 cm. Shanghai's soil is so compact that it has to go 40 centimetres deep, otherwise the carrots bend, split and even rotting roots. And will not leave forth plume. (b) elevation and construction of thorium: using high thorium double-cropping, 20 cm tall. Three days before the seeding, the gutter, which is about 2 cm deep, is filled with water, so that when the water is fully immersed in the soil, the seed is placed at the bottom of the wet ditch. Seeding method (on-demand): white radish: 2-3 grains per den, 25-30 cm. It is then covered with 1. 5 centimetres of earth, which is lightly pressed. Carrot: seeds have gills on their surfaces, graft them off with their hands before planting, mixed in with fine sand sowing or stripping. It is extremely thin (0. 5 cm) and must not be thick, otherwise the soil will be destroyed, resulting in weak seedlings. The art of sakami: "a single slender as a wolf." and when the radish is sprouts, then when there are two real leaves, the seed shall be shrunk, leaving only one of the strongest in each den. It is not inevitable that the fall rains will be heavy and the crowded seedlings will be humid enough to cause frost. Category iii: chasin (garine, onions, pickles)
This type of vegetable is almost “landnuts” at the home of shanghaiers, growing at once and collecting many times。
Garlic: the best seeding period in shanghai is from late september to early october. The choice is for the fat, undamaged garlic. Low-temperature treatment (breaks hibernation): the placement of garlic petals in the freezer room (2°c-5°c) for approximately 10 days is effective in preventing warm winters after early seeding in the autumn. Open shallow trenches, 5 cm deep and 7 - 8 cm long, bearing in mind that the garlic petals are to be “downward” into the sky (head down, point up) and 3 cm thick. The seeding is followed by a permeation of water covering straw to keep it wet and to protect against cold grass. Onions: available throughout the year, but in the autumn of shanghai, the fastest seeding is selected for early september. Onions grow small, the ground must be thin. A one-cm-deep shallow ditch is used, seeds are spilled into the ground and water is sprayed with flowers. Keep the surface wet during the seeding period, which cannot be filled with water, otherwise it is highly likely to cause “seeds”. Category iv: high-end winter foods (violet moss, cyanide, crumbs, crumbs)
This is the unique advantage of shanghai's local autumn。
Collapse: after planting in mid-september, it can also grow in winter snow. It is extremely cold-resistant, is not frozen at minus 8°c, and is better eaten by frost. It is broadcast directly at three to five particles per den, and at the time of seedlings, with a final seedling of one tree per den at a distance of 30 cm. The harvest was extremely late: even the leaves were harvested in november, the salvation of the winter vegetable break。
Category v: live specialisation techniques for fruity vegetables (butter, cabbage, cabbage, cedar)
In the shanghai area, the four types of food must be carefully differentiated between the planting periods and, in the event of a mistime, must be abandoned. In common, they are deep-seated, requiring high levels of fertilizer and requiring high temperature differentials between day and night。
Big cabbage (linear/dry stick type): live to see "deep"
Shanghai is on the air: 25 august - 5 september (after autumn, summer is the best). It's too early to get a virus, and it's too late to be honest。
Key heartbreak management: during the `twilight tree' (leaves in the form of lotus), in the event of continuous rainfall, 0. 2% of potassium phosphate + 0. 1% of the platinum base is sprayed on the side of the leaf, which is the catalyst for a big cabbage. Shanghai soil is prone to a shortage of boron, which can lead to dry heart burns. Vegetables (carbs, oxen) live, with "dry seed" controlled
Shanghai is on air: mid-september-early october (as a spring-covered vegetable). It was easy to broadcast the dishes live, but at high temperatures, they were extremely vulnerable, resulting in no ball。
Vegetables (concerts, infarction): live broadcasting is very easy to “deficit” and follows “fat-to-ball”
Shanghai is on air: late august - early october (several by variety)。
4. Celines (new varieties of mixed broccoli and mustard): most effective live coverage
Shanghai is on air: september - early october. Silanthe is almost a vegetable produced for live broadcasts in the long triangle of autumn, which is resistant to cold, disease, and has many side branches, with harvest periods of more than two months。
Chapter iii: the core technology for planting “sapling” in the long triangle autumn (for clay)
Most of the soil in shanghai is damp, with low organic content, which protects water but is easy to compact. After planting in the fall, there is a constant phenomenon of “good seedlings, but the rain is all over the next few days”. The reason is chinese farming is not timely, it's bad root。
After the rain, tilling (hinges): when the soil surface is white and there are micro-fissures, it is immediately ploughed at depths of 2-3 cm, cutting off the soil cavity tube, maintaining the soil for air and preventing boots from stepping on the soil plate. This is essential for radish and onions. The water-watering principle — “no rain in the morning and no rain” — is that the fall dew is heavy, and the evening watering forms a “high wet cold” that leads to the sudden onset of the disease. Water is poured as much as possible by 8 a. M. To evaporate the surface of the soil during the day. (c) following up on the fatting of seedlings: some 15 days after the seeding, most vegetables are in rapid development. At this time, the temperature in shanghai has fallen and nitrogen fertilizer needs to be supplemented. It is strictly forbidden to sow urea (easy to burn and volatilize). Good practice: one-tenth with rotting manure, one-hundred-and-a-half-hour water, and one-half-hour water。
Chapter 4: autumn pests and pests `more than cure' operational strategies
Shanghai has a high level of humidity and disease. After planting directly, the focus is on three diseases:
Sudden disease (indulgent disease): the cold rain of the seed season is extremely prone. Prevention: polios of polybacteria sprayed 800 times over the face of the sapling after sowing must be dry (rejecting to cover seeds with tidal soil). Pests (jumping beetles, green beetles, aphids): never wait until you see an eye before you take a pill. Before seeding, tea cake powder (slag after oilseed extraction, net purchases, etc.) or bitter alkaline powder (biopesticides) are distributed in the soil, and the underground pests and earthcaps are shielded from residues and are well suited to family gardens. (b) protégration: if the seedling comes out of the rain, the seedling will quickly rise to thinness. Response: stop watering and spread grass-wood ash per acre (just about a layer of frost), which is wet, potassium-added, staggered, “the potion” for planting in the autumn.

Concluding remarks
In the shanghai and long triangle autumn, the core technology is not “high-tech”, but “when responding to the sky, grab the key two things”:
Early harvest: the planting of seeds at the end of august and early september is the key to securing a warm fall. China: after each rain, you bend down to the ground, which is better than any fertilizer。
Using these 2,500-word technical manuals, by tuso, you're probably going to be able to eat the water-spirited autumn before winter. Good luck with the garden
