Causes of Strawberry Seedling suspension and its solution

Strawberry shows poor plant growth in the process of planting, which is not conducive to flower bud differentiation. In fact, strawberry production is to stop seedling, this phenomenon is extremely disadvantageous to strawberry production. So what is the reason for the suspension of strawberries? Come and have a look with the editor.

First, the reason for stopping the seedlings

1. The root system of the seedling is weak.

The quality of strawberry seedlings directly affects the growth of strawberries. generally, the qualified seedlings have more than 12 roots, 4-5 functional leaves, and there are no diseases and insect pests, while the seedlings with low quality will slow down for a long time and grow weakly after planting.

2. Improper fertilizer and water

The application of insufficiently mature organic fertilizer in the early stage caused damage to the strawberry root system and its absorptive capacity in summer, thus affecting the normal growth of the plant. In the fruiting period, fertilizer and water management is also very important, too long watering, will affect the normal growth, too much watering will cause the soil temperature is too low, but also not conducive to root growth.

3. No fruit thinning

In order to increase the yield, many farmers ignore the plant growth, and are often reluctant to sparse the fruit and leave too much fruit, resulting in too much plant load, and many farmers even leave abnormal fruits, so that there is a serious imbalance between reproductive growth and vegetative growth. resulting in plant growth in summer, small leaves, and premature senescence in severe cases.

4. Picking is not timely

If the ripe fruit is not picked in time, it will cause falling seedlings, which will only consume too much plant nutrients, and many farmers generally do not dare to water it in order to prevent rotten fruit when the fruit is ripe, when strawberries are in flower bud differentiation. There is a great demand for water and nutrients. If a large number of ripe fruits can not be picked in time, they can not be watered and fertilized, which hinders the growth of strawberries and weakens the planting.

5. Improper use of drugs

Strawberries are sensitive to triazole pesticides. When strawberries are frequently used in the growing season, strawberry plants are easily dwarfed and yellowed, and the fruit deformity rate is increased. In addition, excessive use of expansion agent will also cause strawberries to rest seedlings, resulting in dull leaves, no luster, and serious premature senility.

II. Solutions

1. Strengthen the management of fertilizer and water

In continuous cloudy days, low temperature and cold weather, try not to water, lest the decrease of ground temperature is not conducive to the growth of strawberries, do not apply high potassium fertilizer alone, balance fertilization before fruit expansion, and use low nitrogen and high potassium fertilizer in the later stage of fruit expansion.

2. Timely harvest

When the temperature is low in winter and spring, it can be harvested when the fruit maturity is 85%, and when the temperature rises after early spring, it can be harvested in advance. Try to pick before harvest, do not cause falling seedlings, the picking time is controlled in the morning, do not pick in the sun.

3. Temperature management

The suitable growth temperature of strawberry root system is 15-20, while the suitable growth temperature of strawberry plant is 20-25 degrees, the suitable temperature of flower bud differentiation is 2-25 degrees, the suitable temperature of flower bud differentiation is below 5 degrees or more than 25 degrees, and the suitable temperature of flowering period is 20-25 degrees. It is beneficial to pollen flower bud, and 14-21 degrees is beneficial to anther cracking.

4. Fruit thinning

Generally robust plants generally retain 7-9 fruits, while generally growing plants retain 5-6 fruits, while weak plants leave 2-3 fruits. If the plant is too small, flower and fruit thinning measures are generally adopted to promote plant growth. In production, flowers and fruits should be thinned in time to reduce nutrient loss. Generally, advanced tidbits are removed first, followed by abnormal fruits, and finally the amount of fruit left is determined according to the growth of the plant.
