Three new varieties of apricot and plum with high quality and high efficiency
1. Extra-early apricot before wheat. The domestic budding variety is a very early-maturing and high-yielding variety with strong tree potential and exuberant growth. it can bear fruit in the second year after planting, with an average fruit weight of 85 grams, a maximum of 125 grams, orange yellow, red on the sunny side, and ripening very early, about a week earlier than Jinyang. Southern Shandong can mature on May 18, with the strong and sweet flavor of domestic apricot. It not only overcomes the shortcomings of low fruit setting rate and low yield of domestic apricot varieties (Hongfeng, Zaohong, Zaohe), but also has the advantages of early fruit and high yield of European apricot (Jinyang, Kate). It is a comprehensive pole.

What should we pay attention to when intercropping peach trees?
Peach intercropping should pay attention to matters: peach trees after planting is still small, intercropping should not be planted with high-stalk crops, to plant peanuts, potatoes and beans is appropriate. The crops should not be too close to the trunk. Generally, about 1 square meter of tree tray can be reserved for newly planted trees, and about 2 to 3 square meters of tree tray should be reserved for early fruit trees to prevent the crops from competing for fertilizer and water with fruit trees. To increase soil organic matter, green manure can be planted between peach trees. Intercropping green manure is an important way to solve the problem of fruit-grain competition for manure.

Experiment on Prevention and Control of Fruit shrinkage Disease of Jujube
In recent years, the occurrence of fruit shrinkage disease of jujube is becoming more and more serious. Jujube fruit generally occurs in the white period, and often produces a large number of fallen fruits within a few days. In general, the disease occurs in the north of 5% Mui 8%. In severe cases, the diseased fruit reaches more than 30% in the north, and the taste of the diseased fruit is too bitter to eat, seriously affecting the quality and yield of jujube fruit. Due to different opinions on the disease factors in different places, our county found that it was only 10 years ago, and there was no successful experience in the prevention and treatment of the disease. Through multi-party access to data and on-the-spot observation, the fruit tree station formulated an experimental scheme for the prevention and treatment of jujube fruit shrinking patients, and achieved good results.

Cultivation techniques of double-season peach
With the development of breeding technology, very early maturing peaches (such as April red peach, May crispy peach) and very late ripening peach (such as snow peach, holy peach, winter peach) appear one after another, which creates favorable conditions for prolonging the supply period of peach fruit market and improving the economic benefits of peach farmers. However, in the actual cultivation, early-maturing peach has early defoliation, many flower buds and large fruit yield, which is easy to cause premature senescence. Late-maturing and very late-ripening peaches consume less nutrients in the early growth stage, and the trees are rich in nutrients and overgrow, resulting in serious fruit drop, which brings difficulties to the cultivation and management of fruit growers. Such as in late-maturing and very late-maturing peach trees

The importance of jujube flower and fruit management
Jujube is a multi-flowered tree species, the differentiation of flowers is very large, but due to the influence of tree body and environmental conditions, the phenomenon of flower and fruit drop is very serious, and the fruit harvest rate is generally only 1-2% of the number of flower buds. There are many reasons for jujube flower and fruit drop. First of all, from the phenological phase of jujube, we can see that the bud stage of jujube is in the period of rapid growth and exuberant growth of jujube, in which phenology overlaps and nutrition competition is very fierce. When entering the early flowering stage, the jujube head is still in the exuberant growth stage, at this time the jujube hanging growth slows down. Several organs of jujube at the same time

High quality cultivation techniques of Huanghua Pear
Huanghua pear is produced by traditional technology with poor quality and low benefit. in order to obtain high quality, high yield and high benefit of Huanghua pear, the following cultivation techniques must be implemented: first, change the traditional pruning method and change the side trunk shape to natural happy shape. The central leader trunk of the pear tree is removed, leaving only three main branches, similar to the pruning shape of a peach tree. Practice has proved that, through this simple measure, the top advantage is weakened, the skeleton branch is obviously thicker, 35 cm thicker than that of the general production garden, and the main branch extends by more than 2 meters. The crown expands, increasing the knot of the second year.
