In areas far away from big cities, choose medium and late maturing varieties that are resistant to storage and transportation. Adult trees are planted with grass between rows and cleared or covered within rows. Therefore, when water is used in high temperature and drought, the photosynthetic capacity of leaves will decline rapidly when the temperature exceeds 35 ℃. The back of the leaf is pubescent when young. The purpose of pruning is to create a beautiful tree shape, that is, to leave those branches in the right position for modeling.

Next, in the growing season, according to the growth situation, pour the rotten thin organic fertilizer once in 3 ~ 4 weeks, add an appropriate amount of nitrogen, phosphorus and potassium fertilizer, and stop fertilization in winter. Once bad growth phenomena such as dry leaves and falling leaves occur, we can take further remedial measures only if we find the real cause of the disease. If it is in the high temperature and strong light environment in summer, shading measures need to be taken in time to avoid being exposed to the sun, and the 3 gallon pots should be placed in the semi shade for maintenance.

North China is generally caused by early-stage bacteria, and pathogenic bacteria overwinter on branches or diseased leaves. In the coming spring, the infection is transmitted by rain or insects. For example, spinach, coriander, garlic sprouts, oatmeal, lettuce and celery, which are common in winter, can be grown in the cold shed. Elm bonsai likes light and is slightly shade resistant. It avoids exposure in summer and autumn and is watered more.

When putting on the basin, you can apply some rotten cake fertilizer or rotten human and animal manure as base fertilizer. Elm bonsai does not need too much fertilization, as long as it is applied once each year in early spring and early autumn. The following Xiaobian will introduce the fertilization methods of elm bonsai. The mining and excavation of elm downhill pile is generally carried out in the dormant period, and in the process of mining and excavation, pay attention to protecting the root system and mining and excavation with soil ball as much as possible.

In winter, there must be few vegetables in other seasons. Although there are many out of season vegetables, the taste is still a little poor. Therefore, while considering beauty, we should also consider practicability, and often take it as the premise that it does not affect the growth of trees. For many years, there was no change of 7 gallon pots soil or application of organic fertilizer, which was caused by the lack of trace elements. Replace some soil or water micro fertilizer.

It can be used as green feed for livestock. It is usually necessary to harvest all the sweet ears in 70 days. According to the fertilizer demand of sweet corn, fertilization is divided into two stages. When there are 7-8 leaves before jointing, apply 4-5kg urea per mu. Especially in the cold winter, it is difficult for Luohan pine to survive the winter outdoors, so it is often not suitable for outdoor planting.

Ridging planting is a successful experience in improving peanut yield. It can significantly increase the yield by increasing 100 fruit weight, 100 kernel weight and rice yield. Sowing early is easy to affect flower bud differentiation. Clearing the tree is to pick up the surrounding soil after peanut emergence, so that the cotyledons are exposed to the ground. The tree has beautiful shape, natural and unrestrained posture, mottled bark and curly branches. When the new leaves are in full bloom, the tree is green and has high ornamental value.

There is no large-scale low temperature phenomenon in southern China. In northern China, it occurs on the leaves of Luohan pine. Although modern people spend a lot of time and energy raising flowers and vegetables, they are still relatively frugal in some unnecessary things. Put the flowerpot upside down on your left hand, put your wrist and fingertip against the edge of the flowerpot, pat the bottom of the 10 gallon pots with your right hand, and then push the root soil down from the bottom hole with your mother finger to let the plant come out.

For the wet situation of purple leaf plum, in addition to watering the newly planted seedlings, it should also be watered once or twice in April, may, June and September. Sick branches and buds, but also pay attention to loosening the soil, so that the plant can grow naturally. Purple leaf plum can be pruned to make bonsai according to its natural shape. The breeding method of purple leaf plum is mainly grafting, cutting and layering, but the survival rate is low, so it is generally not used.
