Disinfection methods of flower culture soil, transplantation and colonization of flowers

Planting includes transplanting and colonization. The method is the same, planting is no longer moving after planting, while transplanting is a cultivation measure before planting to change the planting distance for plants to meet their growth needs.

1. Transplant

The purpose of transplanting is to enlarge the row spacing of all kinds of seedlings, so that the seedlings can get enough nutrition, light and air. At the same time, the main roots of the seedlings are cut off during transplantation, which can make the seedlings produce more lateral roots and form developed roots, which is beneficial to their growth.

Before transplanting, the seedlings sown should generally be thinned between the branches to remove those that are too dense, thin or diseased. The sparse seedlings can also be planted separately. The seedlings planted in the ground were transplanted for the first time when they had 4 or 5 true leaves. Seedlings planted in pots are often transplanted when there are 1 or 2 true leaves. The distance between the rows of the transplanted plants depends on the size of the seedlings, the growth rate of the seedlings and the bed retention period after transplantation. The preparation of seedling bed for seedling transplanting is basically the same as that of sowing seedling bed. When transplanting, the soil should be dry and wet properly, and generally should be transplanted when the soil is dry, but when the soil is too dry, it is easy to wilt the seedlings. It should be watered on the border the day before planting, and the sandalwood should be moved when the upper grain absorbs water and does not stick to the hand. When the soil is wet, it is not only inconvenient to operate, but also the soil is hardened after planting, which is disadvantageous to the growth of seedlings. Do not press too tightly when transplanting, so as not to get hurt. When the soil particles sink with the water, they can be closely connected with the root system. It is better to transplant on a windless and cloudy day, and if the weather is sunny, bright and hot, it should be transplanted in the evening. Before transplantation, it is necessary to distinguish the varieties and avoid confusion. Cut off the main root when digging seedlings, do not hurt the roots, and transplant them with protective roots as far as possible. Digging seedlings and planting should be coordinated, along with digging and planting. If the wind is strong and the evaporation is strong, dig up the young Zhuo to cover and shade. The transplantation hole should be slightly larger to make the root stretch smoothly. The planting depth should be the same as the original planting depth, or a further depth of 1 cm to 2 cm. If it is too shallow, it is easy to lodge; if it is too deep, it will not develop well. Immediately after planting, it should be fully watered and re-watered to ensure sufficient quantity. In times of drought, we should plant and water at the same time. Shade should be provided at the initial stage of summer transplantation to reduce evaporation and avoid wilting.

two。 Colonization

Planting includes planting large seedlings, potted seedlings, stored bulbs, persistent root flowers and native flowers in places where they no longer move. Before planting, according to the needs of plants, improve soil structure, adjust pH, improve drainage conditions, general plants need fertile, loose and well-drained soil. Fertilizer can be mixed during soil preparation or applied to the bottom of the hole after digging. The distance between plants used in planting should be determined according to the adult size of flower plants or the requirements of planting. Digging seedlings, generally should take root soil, the soil is too wet or too cadres should not dig seedlings, how much soil depends on the size of the root system. When trees fall, there is no need to bring soil when they are planted during the dormant period. Evergreen flowers and trees and species that are not easy to transplant must bring complete clumps of mud and tie them up with grass ropes. When planting, holes should be opened, which should be larger and deeper than the root system or mud mass of the seedlings, and the stem base of the seedlings should be raised close to the soil surface. Then shovel the soil around the hole into the hole for about 2 / 3, shake the seedlings so that the soil particles and roots are closely connected, then press the soil outside the root system, and finally fill the hole with loose soil to make it flat and slightly concave with the ground. Water twice immediately after planting. After the grass flower seedlings are planted, they should be watered again the next day. Bulb flowers generally do not need to be watered at the initial stage of planting, but should be watered once if it is too dry. Large persistent root flowers and native flowers should be combined with hate pruning, root damage, rotten roots and withered roots should be cut off. After the seedlings are planted, props should be set up, or rope traction should be set up at three diagonal angles to prevent dumping.
