They are indispensable melons and fruits in summer. now we can plant a few pots on the balcony and have nothing to eat in summer.

One day still seems to be running, unwittingly it is the middle of May, with the rising temperature, the pace of summer is getting closer and closer. As the saying goes, "eat buds in spring, melons in summer, fruits in autumn, and roots in winter." in this hot summer, melons and fruits are better matched with summer. In particular, balsam pear, watermelon and cucumber all have the effects of clearing away heat, replenishing water and nourishing beauty, and are very good summer fruits. Out of love for these melons and fruits, many friends plant bitter melons, watermelons and cucumbers on the balcony, pots on several pots, which can not be finished in summer. So, how to plant these melons and fruits? The following is to introduce their potted methods, interested friends quickly plant a few pots!

1. Potted methods of balsam pear

Balcony potted balcony planting can be direct seeding, but also can raise seedlings and transplant. Balsam pear seeds have a thick seed shell, which is not easy to absorb water. In order to increase the germination rate and reduce diseases, the seeds can be treated before sowing. Seed scalding and soaking in warm water can promote seed germination by absorbing water. Seedlings can be raised with disposable paper cups or plastic cups, etc., first piercing several holes at the bottom, the first Panmi blog in this article, please indicate the source, sow the seeds on fine nutrient soil, cover 1-2cm soil, water thoroughly with a fine hole spray can, keep warm and wet. Specific disposable cup seedling method can see this article of Panmi blog: the method of using disposable cup to raise seedlings; direct seeding 4-5 days can emerge, soaking seeds to promote germination will be faster. When the seed grows to 1-2 true leaves, it can be transplanted and planted. Directly pour out the disposable cup with soil and seedlings, disposable cup is very good for transplanting and planting, which is very suitable for growing vegetables on the family balcony; the container for planting balcony after transplanting can choose clay or plastic flowerpot, or it can be a foam box, with the best diameter above 30cm and the best depth above 30cm, and a certain depth is beneficial to the root extension of balsam pear. No matter what container is used, there must be a leak at the bottom. The surface of the substrate should be lower than the 2cm on the edge of the container, and a small hole slightly larger than the seedling paper cup should be dug in the middle of the container with a gardening shovel; immediately after the seedling is removed, it is put into a small pit on the substrate in the cultivation container, and the surrounding matrix is filled with the matrix, and the matrix around the seedling is gently compacted with both hands. Immediately after planting, pour water thoroughly until water seeps from the basin hole. One balsam pear can be planted in each container within the diameter of 30cm.

When balcony potted plants grow to about 30cm height, start to draw vines, should set up a support, can also be pulled to a strong support with rope, be careful not to let the vines intertwined with each other. The balcony shelf of Fanmi blog can build a simple herringbone bracket, and those with balcony windows can use the brackets to protect the windows, but it is best not to climb onto the metal windows, lest the temperature is too high to bake the vines; during the whole growth period, it is necessary to pinch off the terminal buds, male flowers and rattan whiskers in time, leaving only melons and leaves, so that nutrients are more concentrated for the growth of melons. In the middle and later stages of growth, attention should be paid to the removal of old leaves, diseased leaves and redundant weak lateral vines to facilitate ventilation and light; artificial pollination at flowering stage can improve the fruit rate, usually at 8 ~ 10 o'clock in the morning. You can use a cotton swab to wipe the pollen from the mature male flower on the female flower stigma. Trouble-saving vegetable friends do not need artificial pollination is fine, will also be the result, but less; balsam pear growth period is long, generally every 1-2 weeks to apply mature organic fertilizer, such as chicken manure and so on, do not use chemical fertilizer; when the tumor on the melon peel protruding and expanding, the color is not yet white bright can be harvested. If you leave the seed, you can wait until the peel turns orange before you take it off. The ones you grow may not be as big as those bought on the market, because they are all raised by chemical fertilizers and pesticides, but they are green and healthy, so you can almost pick them and don't get old.

2. Pot planting method of watermelon

Watermelon root system is developed, in order to meet the root growth, need to have enough nutrients, and the basic source of nutrients is the substrate, which requires a large enough container. Generally, the diameter is about 30cm and high 50cm; in addition, in order to permeate, the bottom of the container needs small holes to flow water; the matrix needs to be loose, breathable and nutritious, and the mixture ratio of soil without bacterial infection, peat soil and organic fertilizer is generally chosen. You can choose the seeds of small watermelons (such as Black Beauty, Huang Xiaoyu, etc.). If you eat the seeds left by watermelons, the melons may not be the same, because today's watermelons are all hybrids. It is difficult for large watermelons to grow on the balcony; soak the seeds in water for 3-4 hours before sowing, then sow them into watered soil and cover them with dry soil (do not water immediately after covering the soil, otherwise the soil will harden and the seedlings will be difficult to come out).

Wait until the seedlings are unearthed, they can be watered according to normal management, pay attention to not too much water to prevent rotting roots. Of course, fertilization is essential, it is recommended to use market compound fertilizer, usually you can also pour some rice water (need to be fermented); melon seedlings grow up a little, to straighten out the vines in one direction, or with a bamboo pole or rope to pull up, let the tendrils coil on the bamboo pole or rope, so that melon seedlings can grow upward; watermelon flowers have female flowers and male flowers. The ones with melons below are female flowers. After the watermelon blossoms, the stamens that open on the same day are smeared on the stamens of the female flowers on the same day, and the pollen of the male flowers is scattered on the stigma of the female flowers, which is auxiliary pollination. This is very important. When you plant melons on the balcony, you can't bear melons without pollination. When watermelons begin to grow, if they are pulled up with bamboo poles or ropes, they should be hung up with net pockets or covered with things, otherwise the vines will break when they grow up. When the melon is fully grown and the pattern on the skin begins to become clear, it can be harvested.

Third, the pot method of cucumber.

Choose better containers, flowerpots, wooden pots, foam boxes and professional cultivation boxes to grow cucumbers. The important thing is that the drainage of the selected container basin is good, and the suitable depth is 40cm. The soil chooses well drained and fertile nutritious soil, which is more conducive to the growth of cucumber. After selecting the container, the seeds should be soaked. This step is important to promote seed germination and shorten the growth cycle. Soak the seeds in 50 ℃ warm water for 20 minutes, keep the water temperature constant, and stir continuously during the soaking process. After 20 minutes, soak the seeds in the same water as room temperature for 6-8 hours. Remove the seeds, wrap them in wet hair and put them in an environment of 25-28 ℃ to accelerate germination. When more than half of the seeds are white, they can be sown. Sprinkle the soaked seeds evenly on the surface of the nutrient soil and cover with the thin soil of 1cm. Water immediately after sowing, called planting water, and keep the soil moist for 4-5 days.

Cucumbers are vines, so the scaffolding should be built in time, and the pillars of the supports should be close to the cucumbers, but do not damage the roots of the cucumbers, so that the cucumbers will grow along the supports themselves, and when they grow to about one meter, the terminal buds can be removed to promote cucumber branching. After some time, small flowers can be seen on cucumber seedlings, female flowers with cucumbers and male flowers without cucumbers. Cucumbers can generally pollinate themselves, but artificial pollination is needed in places where there are no insects and no wind, and artificial pollination can also increase yield. you can use a clean brush dipped with the anther of the male flower and then coated on the female flower to complete pollination. After the cucumber fruit, the demand for water and fertilizer increases, need appropriate more fertilization to supplement nutrition, so that more cucumbers can be produced, and the amount of water should also be increased, so that cucumbers can grow rapidly, fresh and tender and watery.
