First, after the application of gibberellin, the plant grows 1 to 2 pieces of young leaves when spraying 10 ~ 2010E-6 gibberellin, each spray 5 ml liquid, interval 1 week, according to the strengths and weaknesses of the situation as appropriate Spray 2 or 3 times to promote growth and development. Second, the bees to promote pollination Strawberry pollination is easy to produce abnormal fruit and irregular fruit set, if the shed stocking 1 to 2 boxes of bees, can significantly improve the fruit setting rate and reduce the occurrence of abnormal fruit. The bee-keeping time is carried out throughout the flowering period, and the amount of stocking is appropriate for 2 beehives per acre. During the pollination period, the daytime temperature is maintained at 20-25°C. Third, budding moderate sparse buds can promote single fruit weight increase, fruit yield increase, fruit size uniform, early maturity, concentrated harvest time, reduce the number of harvest, thereby increasing production value. Strawberry is the first to open the low-grade secondary flower results are good, fruit a big, mature early, high prices. As the flower grades increase, they often fail to form fruit after flowering and become ineffective flowers, or even if some form fruit, they are ineffective because they are too small and have no harvest value. Therefore, when the flower buds are separated until a secondary flower is opened, the unopened flower buds can be eliminated according to the limited fruit amount. Fourth, picking leaves The new leaves of the year occur constantly, and the old leaves continue to form. The old leaves have more substances that inhibit flower bud differentiation and the nutrient consumption is greater than that of photosynthetic accumulation. The diseased leaves with pathogens are easy to spread and spread. Therefore, the old leaves should be removed timely and in appropriate amounts, and the remaining leaves and diseased leaves should be removed promptly and taken out of the park for destruction or deep burial. It can promote flower bud differentiation, reduce nutrient consumption, improve ventilation and light transmission, improve photosynthetic efficiency, reduce the occurrence of diseases and pests, and is beneficial to the growth and development of strawberry plants. 5. Strawberry fruit plants are dwarf, and the fruit drooping after the fruit set is easy to contact with the ground, which can easily cause the fruit to be contaminated by soil and harm the pests. It is also easy to cause uneven coloration of fruits and affect fruit quality. Strawberry mat is best covered with plastic film, combined with soil management, in one fell swoop. Without mulching, chopped straw or wheat straw mats can also be laid after budding. The fruit material should be promptly removed after the fruit is harvested to facilitate field management such as cultivating and fertilizing. 6. In addition to the consumption of the mother plant nutrient, the stem borer strawberry pods are easy to make the plants close and crowded, affecting the ventilation and light transmission. Removal of stolons can significantly reduce consumption, improve lighting, favor flower bud differentiation, enhance wintering ability, and increase fruit yield and quality. The stolons that occur during fruit development should be removed promptly. Manual removal of stalks is costly, and paclobutrazol, qingshui or chlormequat can be tested to suppress the occurrence of stolons. Removal of stolons can be combined with cultivating, cultivating soil, and harvesting leaves. Higher secondary inflorescences are prone to male-female instability, and the removal of certain high secondary flowers and flowers after flowering can not only reduce the malformed fruit rate, but also help concentrate the nutrient supply to the low grade secondary flower development, increase fruit size, and improve uniformity. VII. Strawberry harvesting The strawberry fruit is mainly fresh. It must be harvested when more than 70% of the fruit surface is red. In winter and early spring, the temperature is low. It must be harvested when it matures at 8 to 90%; the temperature gradually changes after early spring. Recovery, harvesting period can be appropriately advanced. Picking should be carried out from 8 to 10 o'clock in the morning or from 4 to 6 o'clock in the afternoon. Do not remove fruits and sun-dried hot fruits to avoid deterioration. When picking lightly, gently, gently, do not damage flower buds, and at the same time to be graded and packed. The correct method for harvesting strawberry fruit is to use the nails of the thumb and forefinger to cut the handle, and then pick it off. The shorter the fruit picking, the better the fruit picking. Otherwise, the fruits will be punctured due to the long handle, affecting the fruit quality. , causing unnecessary losses.
