1, look at the characteristics of the flowering
(1) the time of flowering: under normal circumstances, the male flowers of the kiwifruit generally bloom a little earlier than the female flowers.
(2) the mold of the blossom: the male flowers will have pollen when they first blossom, but the flowers are smaller, while the female kiwifruit trees have larger flowers and no obvious traces of pollen on the petals at the beginning of the blossom. In addition, female flowers have fewer hairs and larger leaves than male flowers.
2. Look at the eye of the bud
Male kiwifruit buds mostly show a kind of "protruding outward", while female kiwifruit buds are mostly "inwardly concave", but this is the majority of the situation, except for a few special varieties and mutations. However, this is the majority of cases, with the exception of a few special varieties and mutations.
3. Look at the branches
The distance between the buds is narrower in male kiwifruit branches, and larger in female kiwifruit trees.
4. Look at the size of the leaves
Generally, male kiwifruit trees have "thick, small, rounded" leaves, while female kiwifruit trees have "thin, large, pointed" leaves.
Spring management
Spring fertilizer field management is the first thing to prevent late frost damage, always pay attention to the weather, and then the trunk of the tree white, if there is no time to make preparations for the damage has already been sprayed with Trim foliar fertilizer and brassinolide to ease the symptoms of frost damage. The next step is to prune the kiwifruit in early spring, removing the old vines and gently wiping out the buds of the main vines to encourage new growth. Finally, it is watering and fertilization, first we have to open a ring-shaped ditch near the plant, and then evenly spread the fertilizer in the ditch and cover it with soil, and then finally around the fertilization out of watering.
Summer management
Summer is usually the representative of high temperature and rain, but also kiwifruit flowering and fruiting time, so the management of this period is very important, the most important thing in this period of time is to carry out fertilizer, we have to according to the plant's growth situation to carry out the most fertilizers, if the plant is weak and yellowish, then we can apply a certain amount of urea, in the flowering of the first ten days. Fertilizer once, half a month after the flowering of the second fertilizer, wait until the kiwifruit fruit after the third fertilizer, usually is to potash and phosphorus fertilizer is mainly. The second thing is that when the temperature is high, we water once in the morning and once in the evening, so as to dissipate the heat, and when there is a lot of rainfall, we should open a ditch to drain the water in a timely manner.
Autumn management
Kiwifruit generally from the end of August began to ripen, and lasted until the end of October, in the ripening of this period if the summer management in place, there is basically no problem, and wait until the kiwifruit harvest is over, that is, in November, we have to begin to turn over the ground, as well as the application of basal fertilizer. Turning the ground should be at least sixty centimeters deep, each kiwifruit seedling should be turned to, fertilizer is mainly organic fertilizer, can be used with nitrogen fertilizer, phosphorus fertilizer, composite fertilizer, fertilizer is still the method of open furrow or ring open furrow to carry out.
Winter management
Kiwifruit's ability to resist cold is very strong, but sometimes freezing occurs, so in order to insure that the winter still need to keep warm, we can increase the application of organic fertilizers to enhance the plant's resistance, followed by the establishment of windbreaks as well as cultivating the soil to protect the dryness, but also in the original pile of straw, which can also play a heat preservation effect. The effect. The second is the need for winter branch pruning, mainly to regulate the relationship between kiwifruit growth and results, so that it grows in a fixed direction for the next year, and at the same time, you can cut off some of the diseased branches, old branches, etc., which will make the kiwifruit yield better in the next year, due to the winter pruning, so after pruning to be treated with pharmaceuticals, or else there will be a disease infection that will cause the plant to rot.
