Matters needing attention in the cultivation of Gongkan

Gong orange is known as the king of citrus. It is a kind of fruit that combines oranges and oranges, that is, the mixed products of oranges and oranges. It has a long history in China and is a tribute to the emperor in ancient times. So what should we pay attention to when growing kumquat? Let's get to know it.

1. Planting

First of all, we should choose the seedlings with developed roots, sturdy ones, no diseases and insect pests, about 60 to 80 centimeters high, and thicker seedlings with stems. The branches and leaves of the seedlings should be pruned properly before planting. If they are planted on flat land, they are generally planted according to row spacing of 3 meters and plant spacing of 2 meters, while sloping land is generally planted with row spacing of 3.5 meters and plant spacing of 2.5 meters. The planting time is generally around the sprouting of the Spring Festival and autumn from October to November every year, and it should be watered properly after planting.

2. Management of young trees

The management of young trees is to promote the growth of branches and leaves, so the principle of fertilization is to apply thin fertilizer frequently, fertilizing once every ten days or so, mainly nitrogen fertilizer, for strong shoots, and after one month of planting, we should apply appropriate amount of urea and irrigate with water. so as not to hurt the roots if the fertilizer is too thick. Topdressing at least 5-6 times a year, and the concentration of fertilizer should gradually increase with the growth of young trees. When applying fertilizer in the second year, in addition to dealing with nitrogen fertilizer, we should also apply ternary compound fertilizer appropriately, and in the third year, we should mainly use compound fertilizer with organic fertilizer.

3. Pruning

In order to promote the results and high yield as soon as possible, reasonable pruning is necessary and top growth is controlled, the methods of wire shaping and bud control are used for pruning and shaping. There are mainly three kinds of tree shape in pruning, one is natural happy shape, the second is trunk shape, and the third is natural round head shape. Shaping and pruning should start with young trees to cultivate good tree shape in order to get high and stable yield. As a result, the trunk of the plant is shorter, the lateral branches are numerous and dense moderately, and the distribution is uniform, the internal branches and leaves of the crown are dense and uniform, the external branches are slightly sparse, and the number of leaves is large.

4. Adult tree management

The fertilizer for adult trees is to promote the growth of its branches and leaves and increase the amount of fruit. after adulthood, fertilizer is applied four times a year, the first time in spring sprouting, mainly nitrogen fertilizer; the second time is before flowering, mainly phosphorus fertilizer; the third time is carried out after flowering, in order to promote fruit growth, mainly potash fertilizer and phosphate fertilizer; the last time is after harvest, it is regarded as protecting the growth of fruit trees, mainly organic fertilizer. In addition, it is necessary to control moisture, especially in the long fruit, moisture can not be too much or too little, otherwise the fruit will crack, in the later stage of fruit growth, it is necessary to control moisture and accumulate more sugar.
