1. Planting management: The ground temperature is high when planting tomatoes in autumn and winter, and the soil film can not be covered after planting, so the planting water should be watered in time, and the new high-fat film should be sprayed to protect moisture and heat preservation, improve soil permeability, and promote the deep rooting of tomato roots.
2. Field management: After the tomato is planted, top dressing and watering should be carried out in a timely manner according to the growth needs, and the pruning and pruning should be done in time, the old and diseased leaves of the lower part should be removed, the ventilation and light transmission should be carried out, and the microclimate environment in the field should be improved.
3. Disease prevention and control: tomato planting and growing in autumn and winter stubble is prone to early blight, leaf mold, gray mold, late blight and other diseases, which should be sprayed in time to kill targeted agents, and at the same time spray a new high-fat film to form a protective film, which greatly improves the utilization rate of effective ingredients, and spray pesticides should pay attention to the use of drugs on the back of leaves.

The water temperature air conditioner of Xinfuda greenhouse is mainly composed of high-efficiency tongue compound heat exchange coal-fired furnace and compound exchange segment water temperature and air exchanger. In winter, the product uses hot water provided by coal-fired stoves as a heat medium for heating; In summer, shallow groundwater or flowing surface water is used as a refrigerant for cooling. Because the equipment has the characteristics of reasonable structure, energy saving and high efficiency and large cooling and heating power, it can be widely used in all kinds of planting greenhouses for heating, cooling, humidity, ventilation and promoting air circulation in the shed, and at the same time, the air in the shed can be heated by adjusting the air duct valve, cooling and humidifying, and the air outside the shed can be passed into the shed after temperature regulation, so as to achieve the purpose of ventilation and natural supplementation of CO2 (can reduce the CO2 concentration of edible fungus greenhouses).
Xinfuda greenhouse air conditioner is a necessary product for the cultivation of vegetable greenhouses, fruit tree greenhouses, breeding greenhouses, mushroom planting greenhouses, flower greenhouses and other facilities to achieve annual production. At the same time, it is also the first choice for plant heating and cooling equipment.
The special air conditioner for the greenhouse can heat, cool, ventilate and adjust the humidity of the edible fungus greenhouse. It also has an insecticidal function, and is an essential product for the annual cultivation of edible fungi. It has the characteristics of low investment and low operating costs.

First raise seedlings, then plant a plant every 20cm, use soil to compact the roots, water, you can survive.
-
For disease prevention, it is good to maintain the temperature and humidity in the shed and ventilate it in a timely manner. During the period when various diseases are frequent, pay attention to the infection of germs, and take appropriate medicine to prevent them.

There are several principles that should be followed during the planting process:
According to the soil fertility conditions, comprehensively consider the environmental nutrients**, and appropriately reduce the amount of nitrogen and phosphorus fertilizers.
The old vegetable shed should pay attention to the application of more compost containing more straw, and less poultry manure such as chicken manure and duck manure, which can restore the soil fertility and supplement the carbon dioxide in the shed, which is also beneficial to salt removal and alleviation of continuous cropping obstacles.
The temperature is low in early spring, the soil nutrients are slow, and the early topdressing should keep up, and after May, reduce nitrogen fertilizer topdressing and increase the use of potassium fertilizer; The temperature in early autumn is high, the soil has a strong ability to organic nutrients, and it is mainly controlled, and no top dressing is required.
It is recommended that fertilization should be closely combined with reasonable irrigation, and it is recommended to use ditch irrigation and drip irrigation under film, with no more than 30 square meters per mu and no more than 22 square meters of sandy soil each time.
For the overwintering tomatoes, sweet corn can be planted by using summer fallow to achieve reasonable crop rotation and overcome continuous cropping obstacles.

<>In recent years, great progress has been made in greenhouse tomato planting technology, and many places have expanded the planting area of greenhouse tomatoes, achieving the goal of having fresh tomatoes on the market throughout the year. Now we want to promote this advanced greenhouse tomato planting method to benefit more people.
1.The number of fruit ears of each plant should be determined according to the planting density, and the size of the fruit can be controlled with the number of fruit ears, no matter what variety generally leaves about 5 fruit ears, and each fruit ear only leaves two or three fruits, which can promote the rapid and large growth of the fruit.
2.After planting, it is the squatting period, and during this period, we need to pay special attention. From planting to fruiting, the period is the squatting period, during which the root system is deeply rooted downward, and the promotion of downward deep rooting is to lay a good foundation for increasing yield.
When watering, you can soak the compound fertilizer in water, stir well, and then water the tomatoes.
3.In order to prevent soil compaction, it is necessary to loosen the soil in a timely manner, and the cultivation can be carried out without the ridge, but it is necessary to pay attention not to hurt the roots, so that the ground temperature can be appropriately increased and the surface air permeability can be increased.
4.Control the temperature suitable for watering to be appropriate and appropriate, when the buds just open the slag flower, it marks the end of the squatting seedling period, then it is time to start watering, about once every 10 days, at the same time of watering to apply urea, if the tomato seedlings grow too vigorously to spray the appropriate amount of booster. When watering, keep the ground temperature above 20 degrees and reduce the amount of air.
5.The main reason for the fruit drop is that the temperature is not suitable, at this time, you can use the plant growth regulator 2,4--D point flower stalk, the concentration should be appropriate and not too much, so as not to produce deformed fruit! If it is caused by too little light, it is necessary to improve the light, if it is caused by insufficient soil moisture, it is necessary to water properly, and if the roots are damaged, it is necessary to carry out top dressing on the roots.
6.Tomato fruit period to ensure the appropriate temperature of about 25 degrees, soil moisture content to 20% to 25% for the best, pay attention to give tomato enough light, to wipe the plastic film frequently, before May to apply the appropriate amount of carbon dioxide, each watering before the spray of Wang Ju insect and disease prevention spray and timely pick the ripe fruit to prevent falling off.
7.When appropriate, ethephon can also be used to ripen tomatoes, and 500-1000ppm ethephon can be applied to the surface of the fruit, which is a faster ripening of tomatoes, and if you are not in a hurry to go to market, let them ripen naturally, you can obtain better quality.
You can go to an equipment manufacturing company, and then use your free time to learn PLC, and use it while learning, so that you can ensure that you can support yourself, and learn more purposefully, maybe you can also invent something to get rich overnight.
Why is there love in the world.
