there is no time limit for indoor potted plants.

the planting time of bitter gourd is usually in March. Some seedlings are first raised in greenhouses or greenhouses, and then transplanted, and can be planted in February in advance.

sowing and propagation

accelerating germination

Field management selects varieties such as large white bitter gourd and green bitter gourd with good quality, high yield and strong disease resistance. Scalding the seeds with hot water at 55℃, stirring, and soaking the seeds for 12 hours when the temperature drops to 3℃. If you gently crack the seed, it will help the seed absorb water and soak it for 8 hours. Then, the seeds were washed and fished out, wrapped in clean gauze and put into a temperature box of about 3℃ to accelerate germination. Wash it with warm water once a day, and bud will begin to appear in 4 ~ 5 days.

sowing

for open cultivation, seedlings can be raised in the greenhouse first. Take the field soil, peat, vermiculite and dried human excrement which have not been planted with melons, and mix them according to the ratio of 1: 1: 1: .5, and add 1 grams of diammonium phosphate per cubic meter, sieve and mix them evenly to prepare nutritious soil. The day before sowing, put the nutrient soil into a 1 cm× 1 cm nutrient bowl (or seedling bed) and water it. Spray the nutrient soil with water again the next day, sprinkle a thin layer of sifted fine soil and sow it. The seeds are covered with a small mound about 1.5 cm thick. Then spread a layer of fine soil again. Sowing in Beijing is generally carried out at the end of March and the beginning of April, and the seedling age is 3-35 days. Planting in the open field after the final frost in early May.

at seedling stage

seal the greenhouse after sowing. A small arch shed is inserted in the border and covered with plastic film to keep the temperature at 3 ~ 35℃ during the day and above 15℃ at night. After 5% emergence, remove the small arch shed membrane in time and cover it with .5 cm sieve fine soil to bridge the cracks and keep the humidity in the soil. Let the air cool down at noon, and then cover the shed film at night. After the seedlings come out, the temperature is kept at 2 ~ 25℃ during the day and around 1℃ at night. See dry watering, control temperature but not water, and keep the seedlings growing healthily. After that, the temperature in the shed will be gradually reduced, and all the shed films will be opened for seedling hardening a few days before planting.

field planting

Bitter gourd is a temperature-tolerant and fertilizer-tolerant crop, and foot fertilizer should be applied. Apply 5 kilograms of high-quality organic fertilizer and 3 kilograms of diammonium phosphate per mu, first make a flat border and water it. When the soil is slightly dry and loose, make a small high border with a width of 8-9 cm and a height of 1-15 cm, and spread plastic film 5-7 days before planting. Two rows per border, spacing between plants is 6 cm, and planting should be done by stringing. Don't dig too deep, so it is not advisable to stop a little after planting. Because bitter gourd grows very strongly, it is necessary to insert herringbone frame in time after planting. Planting 13 ~ 16 plants per mu, using 25 ~ 3 grams of seeds.

cultivation management

field management

after seedling slow-down, water slow-down seedlings with small fire in time, and after a few days, deep tillage. Because of the strong branching ability of the plant, 2 ~ 3 thick vines are selected from the lower part, tied to the shelves, and all the others are knocked out. During this period, water is generally not needed. When the first melon is seated and begins to swell, water it and chase urea 1 ~ 15 kg or ammonium bicarbonate 2 ~ 25 kg with the water.

shed management

thatching and ventilation

thatching is uncovered or pulled every morning and evening until the middle of May of the following year. In rainy and snowy weather in winter, it is necessary to cover the grass cover with a layer of rain-proof film in time to prevent it from getting wet, and at the same time, it can also raise the greenhouse temperature by 2-3℃. When the temperature of the shed exceeds 32℃, the film should be uncovered in time to cool down. When the temperature is 2℃, close the vent to control the temperature of the shed between 25℃ and 3℃.

pruning

when the vines are started to be pulled, the melon seedlings are hoisted with fine nylon ropes to make them grow upwards. Momordica charantia generally does not need pruning, but it is necessary to properly cut off the delicate side branches at the base and the yellow leaves that are too dense and aging, so as to facilitate ventilation and light transmission.

pollination

when bitter gourd blooms, artificial pollination should be carried out every day. The method is: take the male flowers that open that day, remove the petals, and gently smear the stamen pollen on the stigma of the pistil. The suitable pollination time is 9 o'clock in the morning. When pollinating, the young melon is pulled down under the seedling, so that the melon can be hung down, not bent, and has a beautiful appearance.

fertilization

bitter gourd is not tolerant to fertilizer at seedling stage, so it should be applied with less fertilizer and more fertilizer. Generally, it is mainly composed of decomposed chicken manure and nitrogen fertilizer. Generally, it is not necessary to fertilize before the year, but it can be watered. Water should be watered once every 2 days in winter, and a small amount of water should be poured to avoid excessive humidity, which will aggravate the disease and root retting. After sitting on the melon, you should be full of fat water, and apply 7-1 kilograms of urea or compound fertilizer per mu every time you water it, plus about 1 kilograms of decomposed chicken manure. When to plant pineapple potted plants

Generally, in the season when pineapple is abundant, choose fresh pineapple, cut off the terminal bud with a knife, tear off the lower bract, let it dry in the shade for 1-3 days, and let the wound heal, then you can plant potted plants. The following are the growth habits of pineapple:

1. Soil: Pineapple has a wide adaptability to soil. Because the root system is shallow and aerobic, sandy loam or mountain red soil with loose, good drainage and rich organic matter and pH value of 5-5.5 is better, while poor, sticky and poorly drained soil and high groundwater level are not conducive to pineapple growth.

2. Temperature: Pineapple is native to tropical high-temperature and arid areas in South America, and it likes to be warm. It is most suitable to grow at an average annual temperature of 24 ~ 27℃, and can grow in the range of 15 ~ 4℃. It grows slowly below 15℃, and basically stops growing below 1℃. 5℃ is the critical temperature for chilling injury.

3. Water content: Pineapple is drought-tolerant. When the soil is short of water, pineapple plants have the function of self-regulation, reducing transpiration intensity, slowing respiration and saving water stored in leaves to maintain life activities. When there is a serious shortage of water, the leaves are red and yellow, so they must be irrigated in time to prevent dryness. Too much rain and high soil moisture will cause root rot and plant heart rot or wither.

4. Illumination: Pineapple was originally grown in the semi-shaded tropical rain forest, which was more shade-tolerant. Due to long-term artificial cultivation and domestication, the requirement for illumination increased, and it grew well under sufficient illumination, with high sugar content and good quality. Insufficient light leads to slow growth, high acid content and poor quality of fruit. The light decreased by 2% and the yield decreased by 1%. However, if the light is too strong and the temperature is too high, the leaves will turn red and yellow, and the fruit will burn easily. When to plant potted water lilies

Water lilies are mainly propagated by ramets, usually after breaking the hegemony in spring. First, take out the vigorous underground stem from the mud, select a section with new buds, cut it into a section of 6-1 cm as the mother seed, and plant it flat in the mud, but not too deep. Keep the bud level with the soil. After planting, you can put the water in the sun for a while. .....

seeds can also be used for sowing. However, because the fruit of water lily ripens in water, it must be fished in the mud. After fishing, it must be stored in water and sown in shallow cement in spring. When to plant potted garlic seedlings

Plant them at any time.

grow garlic in flowerpots. After peeling garlic, separate it into petals without peeling off the skin, and then plant it in flower pots one by one. Apply some flower fertilizer properly, water it often, and pay attention to basking in the sun often. If the temperature and humidity are suitable, it will germinate in half a month, and it will soon be in full of green. When the garlic seedlings grow up to about 5cm, they can be cut and eaten. Pay attention to the height of 1cm when cutting the garlic seedlings, so as to prevent the growing point from being cut. When to plant potted oranges

Generally, the orange saplings are pruned 1-2 days before the shoots are put out in August-September, and the top buds are subtracted from the branches of the current year, and then they are cut for 1-15cm.

The reasons for pruning potted oranges are as follows:

First, the pot is small, the soil is small, and the nutrients provided are limited, which cannot meet the needs of orange growth and must be pruned;

the second is to adjust the rational distribution of nutrients in the tree through pruning, so that limited nutrients can be supplied to buds and leaves to form more fruiting branches, so as to achieve full flowering and fruiting branches.

when potted tomatoes are planted

there is no special requirement. Introduction to the management of potted tomato breeding

1. Requirements for environmental conditions:

Temperature: the adaptive range is 8-35℃, and the optimal range is 18-25℃; If it is below 3℃, it can be moved into the bedroom or air-conditioned room and put back on the balcony when the temperature rises.

lighting: general balconies and indoor windows with good lighting can be placed

Humidity: potted tomatoes do not require high humidity, so they can be watered in a well-ventilated room

Moisture: it is appropriate to see the moisture, and it is not advisable to water them too often, because too much humidity will cause rotten roots. Generally, when the soil in the basin is white or the leaves are soft and wilting, it should be watered thoroughly. Don't water at noon

2. Fertilization: Fertilization is not needed before the fruit is set in the early stage of growth, and the amount of fertilizer needs to be gradually increased after the fruit is set. Choose high-potassium compound fertilizer according to the growth situation, and

apply liquid fertilizer with a concentration of 1:1 times to the surface of the basin, or use the waste vegetable soup feet from daily life to put them in a rice slop bucket and cover them for fermentation for 7-1 days before watering, which is not only effective, but also environmentally friendly and safe. Fertilization cycle is usually about 7 days.

third, pruning: pruning includes single stem, double stem, topping and so on. In addition to the above, all the redundant branches and leaves should be erased, and at the same time, diseased leaves and dead leaves should be cut off to facilitate ventilation. If the harvest or appreciation is to be prolonged, 1-2 foot buds should be reserved within a certain period of time, and the next generation (foot buds) should be cultivated after the fruit branches on the original pot are harvested. Thus, it can be planted all year round. When to plant sweet potatoes in potted plants

Sweet potatoes can be planted in potted plants all year round.

The sweet potato planted in spring (March) is called spring sweet potato, and the sweet potato planted after wheat harvest (around the end of May) is called wheat stubble sweet potato. My home is in the countryside of northern Anhui, which is generally the case. When to plant potted mulberries, we usually choose to plant them in winter and early spring, and the soil temperature should be kept at about 1-12℃.

When planting in summer and autumn, it is necessary to pay attention not to damage the roots as much as possible and protect the roots of mulberry seedlings. When planting in winter and spring, it is necessary to lightly prune the long main roots to promote more lateral roots.

bury the mulberry seedlings in the substrate, cover with soil and gently lift the roots to extend them, then gently pat the compacted soil with your hands and shovel a layer of loose soil, which is about 3 cm above the rhizome, and then pour enough water to fix the roots. See when to plant pepper and how to plant it in potted plants

Planting strawberries, peppers and cherry tomatoes in potted plants is both ornamental and edible. First raise seedlings, or buy some seedlings. In order to be green, safe and healthy, and grow vigorously, seed is soaked with 1 times of enzyme fertilizer for 3-4 hours, and the enzyme fertilizer is sprayed once at the fourth leaf stage of seedlings, and then sprayed once or twice a month; Apply liquid fertilizer once every 5-7 days. It is guaranteed to be full of vitality and fruits, and it is especially ornamental.
