When do sugar oranges usually be planted? What are the key points of flower promotion techniques?

Shatang orange is a kind of orange variety which is relatively small but tastes very sweet. It is deeply loved by consumers in the market, especially during the Spring Festival, it is often used as a fruit to entertain guests. In recent years, the planting efficiency of sugar orange has been improved. Let's find out when sugar orange is usually planted. What are the key points of flower promotion techniques?

I. planting time and method of sand sugar orange

(1) planting time

The general principle is to plant after the last shoot is old and before the new shoot begins to sprout. Planting is generally divided into three periods throughout the year:

Spring planting: choose the species in April and May with more Rain Water and warm climate. Orange trees are easier to survive and grow faster. Therefore, spring planting can be chosen in places where there is a drought and low temperature in autumn and winter.

Autumn planting: usually from September to November when autumn shoots are ripe and watered. Especially in the cold places where the drought is serious and the cold wind and frost are early, planting should be done as soon as possible, and planting before the middle of October is most beneficial to its growth.

Winter planting: generally selected in January and February, when the cold gradually fades away, the climate begins to warm, and planting before the shoot begins to sprout is of great benefit to its root growth. At this time, the new root grows faster and the survival rate is higher.

(2) planting method

In general, two people cooperate to plant seedlings, one covers the root neck with fine soil, and the other supports and stabilizes the soil. In order to make the roots fit closely with the soil, be sure to irrigate enough water, and at the same time, the people who cover the soil should also cultivate the soil into a copper plate and cover it with a layer of weeds to moisturize.

If Rain Water is insufficient, he should be watered regularly to keep the soil moist, usually once every three or four days, until the plant takes root and survives.

After planting for a week, it can be supported and fixed with a stick or bamboo pole to ensure its survival. After planting, some branches and leaves can be cut off to improve the survival rate.

Second, what are the key points of flower promotion techniques of sand sugar tangerine?

1. Proper topdressing and fertilizer control to make water

Autumn shoot is the most suitable mother branch for fruiting. After turning green, proper fertilization should be added to promote nutrient accumulation. At the same time, fertilizer and water production should be properly controlled to prevent winter shoot sprouting and reduce plant nutrient consumption.

2. the method of ring cutting to promote flower

According to the weather conditions, the branches of fruit trees with luxuriant branches and leaves or those with few blossoms and fruits in the past can be cut and pruned around according to the weather conditions from mid-October to mid-late November, so as to prevent the nutrients from flowing down and accumulate more nutrients in the upper part of the tree. so as to promote flower bud differentiation and improve fruit yield.

Ring cutting needs to use a special ring knife to cut the trunk and branch ring, with it to cut off the cortex, but can not hurt the xylem, at the same time, pay attention to fertilizer after ring cutting, no pesticides to avoid damage to fruit trees, resulting in fallen leaves to reduce production.

3. Spraying paclobutrazol to promote flower

Paclobutrazol spray can be used from mid-October to early December to reduce nutrient consumption and ensure flower bud differentiation so as to increase production.
