When we choose, we must choose the ones with smooth outer surface and no mildew.
We have to choose the size of Sanhong honey pomelo according to our needs. If there are many people in our family, we have to choose a big one. If there are few people in our family, we have to choose a slightly smaller Sanhong honey pomelo. If there are many people in the family, you can't separate the small ones. If there are few people in the family, you can't finish eating them all at once, which is easy to breed bacteria.

Planting methods and techniques of Sanhong honey pomelo
Land selection
Pinghe Manyuan Fengsanhong grapefruit should be built in a place that is sheltered from the wind and sunny, with deep soil layer, good drainage, loose and fertile soil, sufficient water, convenient transportation and no environmental pollution (far away from industrial areas). In mountainous areas, it is advisable to sit on low hills and gentle slopes with a slope below 25 and north to south.
According to different gardens, we should reasonably plan the residential quarters, roads, septic tanks, pools and drainage systems, and make good preparations before planting, such as soil preparation, hole digging, base fertilizer application and soil improvement.
Apply plantar fertilizer
Apply 40——50kg pig pen fertilizer or cow dung 15kg (commercial organic fertilizer can also be used), calcium magnesium phosphate fertilizer 1kg, and 0. 5kg compound fertilizer to each hole. The fertilizer and topsoil are fully mixed to form rich soil, and a small amount of lime is added. Then the rich soil is returned to the hole and piled up to be 20——750px higher than the ground and with a diameter/kloc-0.
The quality of planting directly affects the growth and the 1 fruit-bearing time after planting. In order to improve the quality of planting, the orchard needs to implement unified planning, contiguous planting, alternating arrangement according to a certain row ratio and reasonable close planting. The planting technology of Sanhong honey pomelo is close to that of traditional honey pomelo, so it is advisable to adopt large seedlings for planting.
Planting time and specifications
Choosing good varieties and strong seedlings requires that the leaves of pomelo seedlings are complete, thick and dark green, the roots are intact, the leaves and roots are free of pests and diseases, and pomelo seedlings with yellow leaves are not optional. It can be planted after each new shoot is enriched and before the next shoot. Usually, spring planting should be carried out after the spring shoots are ripe (it is advisable to plant the shoots in Zhixia, beginning of spring before they are plucked) or autumn planting should be carried out after the autumn shoots are ripe (10 month or so). The plant spacing is 3m × 3m in mountainous area (60 plants per mu) and 3m × 4m in flat land (50 plants per mu).
Planting method
Classify the seedlings according to their size, plant the seedlings at the same level together, cut off the long roots and the dense branches, keep 3-4 main branches, and plant the roots with mud. When planting, the soil in the rhizosphere should be tapped carefully, and the root groups should be stretched in all directions. After covering the soil, lift the seedlings slightly upward, and cover them with fine soil after being practical. After planting, it is necessary to spray enough root water and cover it with weeds or straw to ensure survival. Water 5 days after planting, and 6 days after rain in case of rainy days. Generally, chemical fertilizer should not be applied within 1 month after seedlings are planted.
After planting 1 month, topdressing should be done in time according to the growth of seedlings, but only thin decomposed organic fertilizer or nitrogen, phosphorus and potassium compound fertilizer can be topdressing to prevent new roots from being damaged. After that, topdressing1-2 times a month, and the concentration can be gradually increased. Young trees mainly apply nitrogen fertilizer, so as to apply it frequently and thinly.
After survival, the young trees should be cut from the height of 1250px above the ground to promote the emergence of new shoots, and then 3-5 new shoots growing in different directions and evenly distributed will be left as main branches, and then 3 auxiliary branches will be cultivated on each main branch, and corresponding lateral branches will be cultivated on each auxiliary branch, with each branch remaining15-575px long.
Sufficient fertilizer should be applied before each shoot is released, and attention should be paid to bud control and shoot shaping at each shoot-picking stage to promote the germination of more neat and robust new shoots, so as to achieve the purpose of expanding the crown, bearing early and yielding high yield.
After 2 years of planting, the lateral trunk shape was uniformly adopted, and the methods of supporting, pulling, hanging and bud control were adopted to make the crown ventilated and transparent, and the bore bore bore more and stronger mother branches. According to the growth trend of the tree, the nutrient accumulation in the branches and tips is increased to promote early fruiting.
Fertilization principle
Advocate the application of more organic fertilizers and rational application of inorganic fertilizers. And according to the leaves, orchard soil, honey pomelo phenology and other guidance fertilization. Fruit trees do not need chlorine fertilizer.
Fertilization method
Mainly based on soil fertilization, combined with foliar fertilization. Methods such as annular furrow application, strip furrow application, hole application and soil surface fertilization were adopted. Reasonable fertilization can meet the requirements of pomelo trees for nitrogen, phosphorus, potassium and other elements, and achieve the purpose of early fruiting, high yield and high quality.
Apply quick-acting fertilizer before spring shoots germinate to promote early and more spring shoots. In order to promote the number and neatness of autumn shoots, the amount of nitrogen fertilizer should be increased before shooting, and phosphorus and potassium fertilizer should be applied appropriately during the full period of autumn shoots.
Apply 20-30kg pig manure to the plant for accelerating germination, and apply it from the end of February to the beginning of March.
The fruit-keeping fertilizer is mainly topdressing outside the roots, spraying sea elf biostimulant (foliar type) or 0.3% urea +0.2% phosphorus and potassium source pool.
Apply 20-40 kilograms of pig manure to the strong fruit fertilizer plant from the end of June to the beginning of July.
40-60 kg of manure+200 g of urea+0.5 kg of phosphate fertilizer should be applied to fruit-picking plants before and after fruit picking, usually in1February.
