Why do plum trees die after sprouting?
The reasons for the withering of new plum tree buds include root damage to seedlings, insufficient nutrients (G-Y), chemical damage, root problems, and weather. Among them, in the face of sudden natural disasters, we should try our best to make up for the losses and minimize losses. For fruit trees that are not seriously affected, we can use plant growth regulators and amino acid nutritional agents for foliar application to mitigate.
Whether it is plum, grape, cherry, or pear, peach, and other crops, there are varying degrees of new bud withering problems. What exactly causes these issues? Here, we provide a comprehensive explanation of the problem of new bud withering.
There are multiple reasons for the withering of new buds, and we should first analyze the specific cause to find the "root of the problem" before applying the appropriate treatment.
Reasons for the withering of new plum tree buds
1. Withering of new buds caused by root damage to seedlings
This situation occurs when fruit tree seedlings are transplanted with excessive root damage, excessive branch retention, an imbalance in root-crown ratio, and insufficient water and nutrients (G-Y).
Since the nutrients consumed by the plum tree when sprouting are from last autumn's storage, the current nutrients stored in the tree are almost exhausted, and the root function has not yet returned to normal, which can lead to the phenomenon of "new bud withering" mentioned in your question.
Quickly prune the plum tree branches moderately, keeping about 1/3 of the branches, and cut the remaining branches short at the strong buds to reduce the consumption of water and nutrients. Once the roots have mostly recovered, the new shoots will gradually resume growth. Don't forget to water every 7-10 days.
2. Withering of new buds due to insufficient nutrients (G-Y)
Insufficient use of organic fertilizers, excessive use of chemical fertilizers, or long-term use of a single type of fertilizer can lead to nutrient imbalance, pH imbalance, soil acidification, and hardening, severely affecting the growth of plum tree roots.
In severe cases, the activity of absorbent roots is impeded, resulting in the inability of nutrients to be transported to the upper part, causing the terminal buds to stop growing.
Particular emphasis is placed on the use of uncomposted organic fertilizers, which can damage the roots, causing yellowing and slow growth of new tender buds, eventually leading to the withering of new buds.
It is recommended to use Green Continent macro-element water-soluble fertilizers or organic bacterial fertilizers in conjunction with large chemical fertilizers or farmyard manure to supplement beneficial active bacteria in the soil and control bacteria with bacteria.
Supplement more organic matter, trace elements, and organic substances to fully meet the various elements required during the growth period of plum trees, thereby increasing yield and improving quality.
3. Withering of new plum tree buds caused by chemical damage
One of the obvious reasons for the withering of new buds is the damage to the growth points caused by pests such as fruit flies and other insects feeding on the tips of tender buds or the stems below, leading to gradual withering.
Regularly observe the orchard, and once some trees show signs of withered buds, immediately spray with chemicals to control the spread of pests. It is recommended to use emamectin benzoate, thiamethoxam, and功夫菊脂 for foliar application to control and prevent.
4. Withering of new plum tree buds due to root problems
Slow growth, weak growth, or withered terminal buds in plum trees are often related to root problems, such as common root rot, root cancer, and root nodules.
Once the root system of plum trees has a problem, there are few hair roots, the absorbent roots turn yellow, dirty, and black, losing the ability to absorb water and fertilizers.
Unable to transport nutrients from the bottom to the top, the nutrient substances fail to meet the growth needs, leading to hindered development of tender buds, stopping growth, and severe withering.
Root problems should be solved from the root. In general, root problems are related to the soil. Regardless of the cause, we should first solve the soil problem. It is recommended to first kill the pathogenic bacteria or nematode pests and then nurture beneficial bacteria for adjustment.
In the growth period of plum trees, it is recommended to use root cancer control,溃腐灵, andningnanmycin for root irrigation to treat.
5. Withering of new buds caused by weather
In mid-March this year, an unexpected significant drop in temperature occurred nationwide. Within a few dozen hours, plum trees in bloom, some early-maturing apple trees, cherry trees, and apricot trees were widely affected, with large areas of terminal buds and tender shoots withering.
People are suffering, and恶劣 weather is a killer for agriculture. In the face of sudden natural disasters, we should try our best to make up for the losses and reduce them to a minimum.
For fruit trees that are not seriously affected, we can use plant growth regulators and amino acid nutritional agents for foliar application to mitigate.
