The second stage is the early stage of the rapid growth of kiwifruit. When those flowers fall and grow small kiwifruit, it is the early stage of their growth. At this stage, vines will absorb a lot of minerals, and then after some transformation, turn those minerals into the elements they need. Therefore, at this stage, it is necessary to fertilize the vines early to ensure that there are enough nutrients on the vines for them to absorb.
The third stage is the mid-growth period of kiwifruit. At this time, kiwifruit does not grow as fast as it did at first, but it also needs attention. Although the growth rate of kiwifruit has slowed down during the second period, if you look carefully, you will find that the outer skin of kiwifruit has changed. During this period, the skin of kiwifruit will gradually change from cyan to light yellow.
Because the skin is changing slowly, at this time, in order to help the skin change better, growers need to apply nitrogen fertilizer to the vines. Nitrogen fertilizer can not only ensure the normal growth of vines, but also help the skin of kiwifruit to change better. In addition, in addition to supplementing nitrogen fertilizer, compound fertilizer should be added appropriately, which is more suitable for use together.
The fourth stage is the expansion period of kiwifruit, that is, the rapid growth stage of kiwifruit. At this time, kiwifruit is in a critical period. If their heads can't get up during the expansion period, then the kiwifruit will be shaped this year. Therefore, growers should grasp this stage, in which not only the nutrients in the soil, but also the moisture in the soil should be considered.
