Is Sanhong honey pomelo a red heart honey pomelo?
It can only be said that Sanhong honey pomelo belongs to a kind of red heart honey pomelo.
Although Sanhong Honey Pomelo and Red Heart Honey Pomelo are both red soil, Sanhong Honey Pomelo is called Sanhong because it is all red from the skin to the pulp, while some varieties of Red Heart Honey Pomelo in the market have red pulp, but the skin is not red.
Difference between Sanhong Honey Pomelo and Red Heart Honey Pomelo
1, Sanhong honey pomelo not only has the characteristics of red flesh honey pomelo, but also the skin of the fruit is pale pink under the corresponding leaves and the sponge layer under the skin is pink.
2. The flesh is rose-red, and the nutritional elements are higher than that of red-fleshed pomelo. The latest variety Guanxi red-skinned red-fleshed pomelo has high stability, large fruit and thin skin, seedless flesh, bright color, soft juice, sweet and slightly sour. It is characterized by early maturity, high yield and excellent quality.
3. Red-heart honey pomelo only has red meat, while Sanhong honey pomelo has red skin and red hair and red meat.
Planting techniques of Sanhong honey pomelo
1, establishment of pomelo orchard: Choose to build the orchard in sandy loam zone which is sheltered from the wind and sunny, rich in water resources, with deep and fertile soil layers, and the garden has the same terrace, with the row spacing of 3 meters ×3 meters, and the planting method is triangle. Red-skinned and red-fleshed pomelo can be planted all year round as long as the new shoots are ripe.
2. Selection of robust seedlings: One-year-old grafted seedlings with developed roots and robust growth are selected for planting. Under good management conditions, the seedlings will soon resume growth and crown formation will be faster.
3. Enlarge holes and improve soil fertility: The important measures to improve site conditions are the basis of early fruiting, high quality and high yield. Generally, hole enlargement and soil improvement begin in the second year after planting, and the best effect is achieved in the third year. The specific method is to dig trenches with a depth of 60-70cm and a width of 40-50cm symmetrically on both sides under the crown drip line, and fill in one load of green manure and one load of burnt soil,1.5kg of calcium magnesium phosphate fertilizer, and a proper amount of lime and topsoil, then apply them in layers and compact them to improve the soil.
4, reasonable pruning, proper girdling:
(1) Pruning principle: thinning branches, cutting more branches at the periphery of the crown and less branches at the inner chamber.
② Pruning time: Young pomelo trees are generally pruned in two times, namely summer pruning and winter pruning; Results Pomelo trees were generally pruned in three times, namely, spring pruning, summer pruning and winter pruning, with spring pruning in February-March, summer pruning in May-July and winter pruning in half a month after fruit picking, that is,10-1month. Pruning method: instead of "one size fits all" method, focus on thinning the peripheral branches, and the pruning method of "opening skylight" can be used for dense crown. This method can effectively control the crown, promote the germination of the inner cavity branches, and avoid the reduction of production due to re-cutting. The bearing branches, dead branches, diseased branches and weak branches should be cut off. In late September, the pomelo trees that are flourishing and do not bloom or bloom less are girdled.
5. Fertilization method: annular furrow application is adopted, and the times of fertilization are 3-4 times throughout the year according to the requirements of "autumn application of base fertilizer, careful application of accelerating germination fertilizer, and combined application of fruit preservation and strong fruit fertilizer".
6. Reasonable fruit thinning and bagging: First, the stunted deformed fruits, small fruits and diseased fruits should be thinned, and the fruit hanging amount should generally be (160-200):1. After thinning and fixing the fruit, bagging should be carried out when the young fruit grows to a single fruit weight of100-150g and the fruit transverse diameter is about 5cm. When bagging, attention should be paid to the width and tightness, so as not to loosen the bag mouth or damage the fruit handle.
Spring is the initial stage of rooting, Changchun shoots, long spikes, flowering and young fruits of red-skinned and red-fleshed honey pomelo. This period, such as pests and diseases, lack of fertilizer and drought, has a direct impact on the strong shoots, strong flowers and fruit-setting rate of pomelo trees, which is the key period to improve the yield of that year. It is necessary to take various technical measures of spring tube in time to promote strong shoots and flowers, improve the fruit setting rate and win a bumper harvest.
