Special early fruit and new variety Li Guan Guan Li
Guan Gong is a special early-fruit type Li variety. The female parent is Mai Huang Li. You were originally sweet in March. 1 Characteristics of varieties 1) The results are early and the yield is high. The variety has good early fruiting ability, and the grafted seedlings become flowers in the same year, and they see fruits in the year after planting. The second year 100% flowering result of bud seedlings, the strain producing 5kg, the highest yield in the 3rd year up to 15kg, entering the full fruit period after the 4th year, generally 667? The output can reach 2500kg or so. 2) Mature and good quality. The variety blossoms in mid-to late March and the fruit matures around mid-May. The maturity period in 2001 was May 15, and the maturity period in 2002 was May 20. Fruit development period 45 to 50 days, the fruit is nearly round, the background is yellow, there are fruit spots, full of red, beautiful and beautiful, there is a little fruit powder. The average fruit weight 85g. Yellow flesh, sweet flavor, rich aroma, sweet and sour, high sugar content, sticky core, soluble solids 12.6%, excellent quality. Timely harvest can be stored at room temperature for 10 days. 3) Strong adaptability. The species has a moderate tree vigor and a high self-pollination rate. If the pollination tree is configured, its yield is higher. There are no special requirements for the soil conditions, not only for the plains, but also for the hills and mountains. Strong resistance to disease, special resistance to aphids, anti-bacterial perforation. Strong resistance. Due to the late flowering and sprouting time of the common plum varieties, the ability to resist cold and cold has laid a good foundation for high yield and stable production. The fruit matures early and there are few pests and diseases. When selecting cultivation sites, low-lying plots should be avoided. 2 Cultivation Techniques According to the soil and cultivation management level, the strains can be selected with a row spacing of 2 to 3 m3 to 4 m. Due to the site conditions and the soil conditions, the site preparation can be selected by digging trenches, digging large holes, or raising the ridge by straight raising. The 80cm80cm ditch can be planted on the barren hills. For deep soil and sandy soil, do not dig trenches, dig 60cm60cm large hole, or directly ridging elevation planting. Regardless of the approach taken, ridicule must be raised. In the year of planting, the early stage was mainly to strengthen fertilizer and water management and promote shoot growth. When the shoot reaches 30cm, the heart is picked up in time to promote branching. In the later period, it is necessary to control vegetative growth and promote flower bud differentiation. In the middle of July, 15% of paclobutrazol could be sprayed with 200-300 times of liquid, and then sprayed again 15 days later, with obvious flowering effect. It is advisable that the two main branches or the three main branches of the tree are naturally happy. We must try our best to ensure that we can achieve fruitful results. Before and after flowering, insecticides were sprayed to control aphids. After the fruits were harvested, they were observed to be pruned in summer and sprayed to control leafhoppers and leaf roller moths. China Agricultural Network Editor
