1. Feed honey insufficiency affects reproduction
There is no panic in the family, bees are the same, the lack of memory honey, a direct impact on young larvae nurturing, a lot of people as long as there is a sporadic source of honey can not insist on feeding. The normal standard is that the upper frame beam must be covered with honey on both sides, and no attention should be paid to feeding pollen, resulting in underdevelopment of the young bees. It depends on the condition of the honey bees. The outside source of honey is much less to feed and can not be interrupted.
2 spleen too fierce dispersion temperature
The cold current is the most unfavorable to bee colony breeding. We must always watch the weather forecast and observe the weather. When the cold current comes, the spleen should be stopped temporarily, and the newly added spleen should be prevented from becoming a sequestered plate due to agglomeration and nursing. The rule of adding spleen is to adjust from the outside to the inside, cut the spleen of the spleen and add it to the middle of the group, and then add the new spleen to the outermost, one at a time, to develop the situation in the Tachibana at a faster rate, and it can be added in almost two days. once.
3. Add the box to keep warm
The use of horizontal boxes containing thirteen four-boxes in the spring is the best. After the boxes are filled, the conditions for adding the boxes are considered to be relatively stable, and the young bees are out of the house in a congested state. In the first time, up to two people were allowed to fill cotton and other insulation materials in an idle manner.
4. The group momentum is too weak to be merged
Why some people do not have high returns? The key is that there is no strong group breeding, and even the honey box can not reach the honeymoon. The weak group is the most likely to cause the theft of the bee, and the resistance to disease is much worse. If the beginning of the summer is less than six or seven boxes should be merged into a box group, do not expect the hedgehog can be slowly raised, to prepare for the Vitex bark, strong group is to seize the basis of high yield.
5. Humidity is prone to big belly disease
Due to the cold current, feeding honey, large moisture, coupled with strict packaging box, the box does not evaporate moisture, the occurrence of large belly disease (climbing bee) is the highest probability, the best way to reduce humidity is to warm the weather and the weather insulation Drying of objects, excessive humidity should be replaced with a box, so that the inside of the box is clean, no odor.
Strawberry flower and fruit management
The fruiting period of strawberry blossoms is from April to May. This period requires 80% of the water capacity in the field, 12 to 15 hours of sunshine, and a temperature of 18 to 26°C. The management points are as follows.
1. Dressing
From late March to early April, 10 to 15 kilograms of urea or compound fertilizer is applied to every 667 square meters of land in order to accelerate plant growth, facilitate the development of new leaves, and promote flowering results. Top dressing should be done in conjunction with watering to ensure that the soil is moist. Foliar spraying 0.3% to 0.5% of potassium dihydrogen phosphate 2 to 3 times.
2. Remove stems
Removal of strawberry stalks can increase production by 40% to 50%. For the need of breeding, appropriate amount of stolons can be left. Excess stems consume large amounts of nutrients and affect subsequent flower bud differentiation. It should be removed once the stolons have just grown, 3 to 4 times a year.
3. Lei Lei
Flowers that bloom behind the inflorescence of the strawberry often do not form fruit, have no economic value and consume nutrients. It is advisable to remove the buds when they are separated from each other to remove 1/5 to 1/4 of the inflorescence, and the weak inflorescence does not have to remain.
4. Removing leaves
The new leaves of strawberries occur continuously throughout the year, and the old leaves are successively yellow. In the flowering and fruiting period, the old leaves and diseased leaves should be removed promptly and wiped together with weakly growing lateral buds. This can effectively reduce nutrient consumption and enhance ventilation and light transmission between plants.
5. Fruit
Strawberry plants are dwarf and their fruits easily fall down and touch the ground. They are contaminated by soil and harmed by pests and diseases. They also cause uneven coloration of the fruit. The countermeasures were: using chopped straw or wheat straw, laying around the plants. This is even more important in the absence of mulching film and rainy areas.
6. Disease prevention
To control powdery mildew, leaf spot, and gray mold during flowering, spray 50% carbendazim 500 times, 70% thiophanate-methyl 1000 times, 20% rustin emulsion 1500 times, and 2% Wuyi Aqueomycin 200 times liquid and so on.
7. Control pests
For aphids 50% anti-inferiority WP 2000 to 3000 times, or 2.5% Uranus EC 3000 times. If spider mites were found, they were sprayed with 5% Nisolate EC 2000 times, or 20% compound Liuyangmycin EC 1000 times. Note that pesticides are banned within 20 days before harvesting.
8. timely harvest
Ripe strawberries are tender and juicy and must be harvested in time to avoid rot. Harvesting can be arranged in stages, picking up once a day or two in the morning after the dew is dry and before the hot midday heat, and the ripe fruit is harvested. For fresh food and canned food, eight ripeness is appropriate, requiring that the pulp be hard, have a delicious color, and have a complete shape.
