Planting vegetables on the balcony-- Tomato

According to nutritionist research determination: 50 grams per person per day to eat 100 grams of fresh tomatoes, can meet the human body on several vitamins and minerals needs. Tomato contains "tomato element", has the effect of inhibiting bacteria; contains malic acid, citric acid and sugar, help digestion function. The vegetables that can be planted on the tomato balcony are easy to use. Small vegetable farmers may wish to add a touch of red to their small vegetable garden.

Cultivation techniques of tomato on balcony

1. variety selection

Choose disease-resistant, high-quality, high-yield, good commercial varieties.

2. cultivation environment

Tomato is the vegetable that likes warm light, choose the balcony with better light especially to face south balcony is ideal, sunshine is sufficient.

3. Cultivation season:

It can be cultivated in spring, summer and autumn, but it is not resistant to heat. It is better to plant in spring and summer on the family balcony.

4. Substrate treatment and seeding

(1) Substrate treatment before sowing

New substrate treatment: 1-2 days before planting, keep the original state of the pot substrate without turning, wet the substrate with clean water to the bottom, and make the substrate wet. It is also possible to carry out substrate treatment and sowing at the same time, but it is forbidden to cause rotten seeds due to too wet substrate and irregular germination due to too dry substrate.

Used substrate treatment: If the substrate used in the previous season is preferably watered and rinsed before sowing in the next season or placed in the open air after raining, the substrate with about 1/3cm of surface layer is added with the distributed bio-organic fertilizer A and mixed evenly for the topsoil and covering of this batch of sowing, and then the remaining substrate is added with the distributed bio-organic fertilizer B and mixed evenly to make the planting bottom substrate. Avoid continuous cropping of crops of the same family in multiple seasons.

(Used substrate treatment: If the substrate used in the previous season is better watered and rinsed before sowing in the next season or placed in the open air after rain, then the remaining substrate is added to the distributed bio-organic fertilizer B and mixed evenly to make planting substrate. The distributed cultivation substrate blocks G are placed in planting pots and 2-3 are placed for the second season sowing. Avoid planting crops of the same family in multiple seasons.) Either way.

(2) Seed treatment and sowing: seeds are soaked in warm water at 50-55℃ for 8-10 hours, and then directly sown in cultivation pots. Sow a seed at 15-20cm. After sowing, cover with 1 cm substrate, cover with plastic film, and break the film after the seedlings grow out. 5-6 Leaf time seedlings, gently pull out excess seedlings, each pot to retain 1-2 strong seedlings, pay attention to pull out seedlings do not damage the roots of seedlings retained.

(3) Sowing time: The local temperature is stable through 12℃, depending on different areas, the spring seedlings are generally sown from late February to March, and the seedlings can be transplanted in nutrient pots or nutrient bags if conditions permit. 1-2 plants per pot.

5. planting management

（1）. Water management: tomato growth period is longer, the substrate is dry and wet, see dry and then water, control watering before the results, after the results to keep the pot soil wet. Choose morning watering is better, keep the soil moist all day, avoid excessive watering, drainage hole at the bottom of the basin unobstructed do not accumulate water.

（2）. Fertilization management: tomato root system developed, large fertilizer requirements, nitrogen, phosphorus, potassium requirements ratio of 2.5: 1:5; young seedling stage application of "seedling" biological organic fertilizer D1 bag mixed with 1500ml water, nitrogen fertilizer + appropriate phosphorus and potassium fertilizer to promote seedling nutritional growth; After the first panicle and fruit begin to expand, apply the second topdressing biological organic fertilizer E 1 bag, when the first panicle and fruit are about to mature, when the second panicle and fruit expand, apply the third topdressing biological organic fertilizer E 1 bag, harvest the first to second panicle and fruit, rapidly grow the third to fourth panicle and fruit, and apply the fourth topdressing biological organic fertilizer E 1 bag fertilizer.

（3）. Branching: Remove the buds in time when the lateral buds are 3-5cm to promote flowering and fruiting.

（4）. pruning

Single pruning: keep one trunk and cut off all other branches. Single pruning can be used for planting two plants in one pot.

Double trunk pruning: retain two trunks, remove all others. Double trunk pruning can be used if only one plant is planted in a pot.

（5）. Thinning flowers and fruits: topping when plant height is 80-100 cm. Remove the heart leaf at the top, leave two leaves to pick the heart, and retain the lateral branches on it. In addition to cherry tomatoes, fruits should be thinned in time when there are too many flowers and fruits, and 4-6 fruits should be reserved for each unit.

（6）. Pest control: sweet and sour liquid trap cutworm; artificial removal of insect eggs and killing pests.

（7）. Harvesting: Tomatoes are harvested in batches after red ripening
