In the present invention, the tomato fruit is preferably harvested when the top of the tomato fruit starts to turn slightly red. When harvesting, the tomato fruit should be picked lightly, preferably without fruit stalks, so as to prevent the fruits from being stabbed each other during shipment.

Below in conjunction with embodiment the tomato rain shelter cultivation method provided by the present invention is described in detail, but they can not be interpreted as the limitation of protection scope of the present invention.

Example 1

Step 1: Arrangement of stubble, rain-shelter tomatoes are planted once a year, planted in Jichang Town, Dushan County in mid-January of that year, planted in mid-April, and harvested from early July to late November ^; the yield per 667m2 can reach More than 5000kg.

Step 2: Build tomato rain-shelter cultivation facilities as shown in Figures 1-3.

Step 3: Variety selection, choose large-fruit tomato varieties that are resistant to low light, humidity, high yield, and good quality, such as "Gangshi 319" and Zhenxing 305".

Step 4: Growing Seedlings

(1) Laying of electric hotbeds: every 667m ² cultivation area needs to be equipped with electric hotbeds with an area of 25-30m ² . Choose to dig out about 20cm thick bed soil in a plastic greenhouse that has not grown solanaceous vegetables, mix the dug out bed soil with decomposed organic fertilizer at a ratio of 2:1, and sieve to form the seedbed soil, and then put the seedbed Soil and carbendazim wettable powder are mixed at a ratio of 20:1 and set aside. Spread a layer of straw or sawdust at the bottom of the bed where the bed soil has been dug out, and then spread a layer of plastic film, and then spread a 3cm thick seedbed soil on the plastic film. The two sides are slightly thinner, and the middle is slightly denser, and then the seedbed soil is evenly put back on the seedbed, and the thickness of the covering soil is 8-10cm.

(2) Seed soaking and germination: use warm soup soaking method, soak in 20-30°C water for 2-3 hours, then soak in 55-60°C warm water for 15 minutes, and then soak in warm water at about 25°C for 6-8 hours. After the seeds absorb water and swell, take them out and place them at 25-28°C to accelerate germination until the seeds are white.

(3) Sowing: Start sowing on January 16, turn on the electric heating hotbed one day before sowing, and sow the germinated seeds evenly on the electric heating hotbed after the temperature of the bed soil rises to 20-25°C, cover the soil with 1-2cm, And lay a small shed on the seedbed.

(4) Seedling stage management: Adjust the temperature controller to about 25°C, keep the temperature at 21-25°C during the day and 15-20°C at night, so as to promote the rapid emergence of tomato seedlings. If the tomato seedlings unearthed at this time have a top shell phenomenon due to too thin covering soil, they should be covered with soil again immediately. After emergence, depending on the weather conditions, remove the film and ventilate appropriately at noon. At this time, the daytime temperature is controlled at 20-25°C, the night temperature is controlled at 13-15°C, and the humidity is controlled at 70-80%. The seedlings were hardened 7 days before planting, and the temperature was kept at 15-20°C during the day and 5-10°C at night.

Step 5: Soil preparation, furrowing, fertilization, and mulching.

7 days before planting, soil preparation, furrowing, fertilization and mulching were carried out. The land is deeply plowed to form deep ditches and high furrows, the furrows are 1.6m wide, the furrow height is 30cm, and the furrow surface width is 1.4m.

Apply 3000kg of decomposed organic fertilizer and 50kg of compound fertilizer to each mu of ditch, open a ditch in the middle of the furrow, spread the fertilizer evenly in the ditch and cover with soil, keep the furrow height of 30cm and width of 1.4m after covering with soil.

Lay black plastic film on the furrow surface to play a role in heat preservation, moisture conservation and weed control.

Step 5: Colonization

Carry out tomato colonization after the last frost around April 10. When the seedlings are 10-15cm high and have 5-6 true leaves, they can be colonized. The row spacing between plants is 50cm×30cm. When planting, water thoroughly, cultivate and loosen the soil frequently, pour seedling water once after 5-7 days, and then cultivate continuously for 2-3 times, and squat the seedlings appropriately according to the variety, seedling age, soil quality, soil moisture, and seedling growth.

Step 6: Field Management

(1) Build a frame to draw vines

When the tomato plants are about 30-40cm high, use thin bamboo poles about 2m long as supports, one pole for each plant, to form a "herringbone" frame, and use plastic ropes to tie each vine to each plant when 3-4 leaves are born. on the bamboo pole. When tying the vines, be careful not to damage the stems, leaves, flowers and fruits. Tie the fruit ears to the inside of the bracket to avoid damage to the fruit and sunburn. Tie the tomato vines and the tie ropes into an "8" shape, and tie the vines on the shelves in time to avoid Lodging broken vines or overlapping leggy.

(2) Pruning and topping and flower thinning and fruit thinning

Take double-trunk pruning, except keep the main trunk, select the first side branch under the first inflorescence as the second main fruiting branch, and remove all other side branches. There are many tomato fruits. If left to grow, the fruit size will be uneven and there will be many inferior products. Therefore, flower thinning and fruit thinning should be carried out. Under normal circumstances, 4-5 fruits can be left on each branch.

(3) Remove old leaves

In the later stage, the diseased leaves, old leaves, yellow leaves, deformed fruits and diseased fruits in the lower part of the plants should be removed in time, and transported out of the field for centralized treatment.

(4) Fertilizer and water management

When planting, water enough for planting, and once 5-7 days after planting, water the seedlings slowly, and no longer water before fruit setting, mainly squatting seedlings in intertillage. Start watering after the first fruit set, and then maintain sufficient water supply, and maintain the soil moisture content at about 70%-80%.

When the first fruit is as big as a table tennis ball, 20 kg of nitrogen, phosphorus and potassium ternary compound fertilizer is topdressed per mu, and topdressing is applied once after harvesting one fruit. After the full fruit period, in addition to the normal topdressing, spray 0.3% potassium dihydrogen phosphate solution on the leaves for topdressing outside the roots to promote fruit coloring and prevent premature aging.

Step 7: Pest Control

There are fewer pests and diseases in tomato rain-shelter cultivation, especially early blight and late blight. The main pests and diseases are Botrytis cinerea, leaf mold, etc. Botrytis is sprayed with 50% Propicon WP 1500 times liquid; leaf mold is sprayed with 25% propiconazole EC 3000 times liquid, every 5-7 Once a day, twice can be.

Step 8: Harvesting

The tomato fruit can be harvested when the top of the tomato fruit starts to turn slightly red. When harvesting, it should be picked gently, and it is best not to pick the fruit stalk when picking, so as to prevent the fruits from being stabbed each other in the shipment.

The invention provides a tomato rain-shelter cultivation method, which can effectively avoid or reduce tomato early blight, late blight and other diseases, reduce the frequency of pesticide application, reduce soil pollution, save man-hours and costs, and simultaneously increase yield.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
