No continuous cropping with Solanaceae crops. And cruciferous vegetables. We should also remove weeds in time and maintain field hygiene. These nutrients can be supplemented by the application of various organic and inorganic fertilizers. During the fertilization period of fruit trees, fruit trees are generally fertilized 4-5 times a year. Avoid direct sunlight in midsummer and put it in a shady and ventilated place. Combined with the local climate conditions, do not supply water in rainy weather.

Sowing from September to October, planting in December and harvesting from April to June of the next year. Sowing from February to March, planting from April to May and harvesting from June to August. Sowing from March to April, planting from April to may, and harvesting from July to November. Irrigation between borders to facilitate flower bud differentiation. Therefore, there are many methods of 1 gallon nursery pots soil disinfection. At present, the following are mainly used. It's not easy to agglomerate because of the high humidity, especially in the case of diatomite.

It is generally decided to raise seedlings in the protected area in February and plant them after the local late frost period. It is best in spring. Generally, it is planted in January and settled in February of the next year. Dig deep into the soil for at least 30cm, apply base fertilizer and break up large soil blocks to ensure that the temperature at the depth of 20cm is at least above 8 ℃. The higher the temperature is, the stronger the fumigation effect is. The mixed use of the two has the advantages of high efficiency, no pollution, convenience and topdressing effect. The preparation ratio of washing powder, urea and water is 1:3:300.

Strictly control the temperature. The daytime temperature should be controlled at 25 ℃ ~ 30 ℃, the night temperature should be kept at 14 ℃ ~ 16 ℃, and the temperature difference between day and night should not exceed 15 ℃. During fermentation, the temperature should be controlled at 50 ℃ - 60 ℃, which is the most favorable for the activity of fiber decomposing bacteria. Generally, when the garlic moss pulls out the leaf sheath and begins to bend, it is a suitable time to harvest the garlic moss. The harvest of garlic moss day and night has a great impact on the yield and quality of garlic moss.

It acts as a pillar to make vegetable plants stand in the soil and make the upper stems, leaves and fruits dependent. Afraid of waterlogging, the ground temperature will significantly affect the growth and development of roots. Therefore, when setting the value of organic vegetables, keep me away from me for ventilation and light transmission. Ponding in 15 gallon nursery pots soil is easy to cause root rot. Because the flowering period of Platycodon grandiflorum is long, it will consume a lot of nutrients and affect the growth of roots.

Wax peony is a very good horticultural variety. Wax peony needs plenty of sunshine and a cool and dry environment. It is resistant to half shade and avoid muggy and damp. Put the garlic that has gone through the root plate and removed the old garlic stalk into the cultivation border one by one. After planting, fertilizer and water management, garlic seedling production does not need to squat seedlings, but can be promoted to the end. Camellia is often seen, but the incubation period of camellia flower bud is long, and a lot of nutrients need to be consumed from pregnant bud to flowering stage.

At the same time, Cypripedium likes a relatively dark environment and cannot accept strong light irradiation. After being irradiated, its color and growth will be affected. Platycodon grandiflorum can be eaten as wild vegetables and young leaves can also be pickled into amaranth. Platycodon grandiflorum is a very famous pickle ingredient in North Korea and Yanbian. The technical requirements for seedling raising are relatively high. Do not operate blindly. It must be carried out under the guidance of professional and technical personnel.

The test results for many years show that the applied farmyard fertilizer must be fully decomposed through composting, so as to avoid root burning caused by high temperature during fermentation. According to the local microclimate, keep 5 leaves per plant, maintain their own growth balance, and achieve the purpose of effective combination of planting and breeding. During the harvest period, in order to prevent the yield reduction caused by ponding and rotten roots in the 5 gallon plant pots, the drainage ditch should be done in time when it is hot and rainy in summer.

Select seed potatoes 20-30 days before planting. Check and supplement seedlings, and maintain soil moisture and stable ground temperature after middle tillage and grass elimination and colonization. For water management, soil moisture is mainly used to provide water for plants before budding, and rainy weather should be avoided during harvest. Generally, seed potatoes are selected, and then the sprouts of seed potatoes are placed upward, and the membrane holes are sealed with fine soil.
