Pearl guava and its efficient cultivation method
2019-07-11 15:02:12
The pearl guava is a genus of guava of the myrtaceae family, native to tropical America. Because of its characteristics of easy cultivation, early harvesting, high quality, and high market selling price, it has become the first choice for the structural adjustment of Guangxi's fruit varieties. one. The cultivation techniques are now described below.
1. Variety introduction pearl guava adaptability, easy planting, extensive management, fewer pests and diseases. The results can be blossomed after 6-8 months, and the results can be produced in the following season. The flowering period is concentrated in April-May and August-October, and the mature period is concentrated in July-September and December-12. -January. In the first year, the strain produced about 10 fruits and the second year produced 15 to 25 fruits. Fruit pear-shaped, single fruit weight 400 - 600 grams, the largest 1000 grams, thin skin, yellow-green, thick flesh, sweet and crisp, less heart seed, nutrient-rich, for fresh or processed.
2. During the cultivation season, pearl guava is a tropical fruit that can be grown in parts of southern, central and northern Guangxi. In addition to the cold winter in the south, it can be planted in other seasons.
3. Before planting pearl guava adaptability, flat land, paddy fields, hills, slopes can be planted, but also in the family balcony, greenhouse bonsai. It does not require strict soil requirements. It is better to plant sandy soils and sandy loam with deep, fertile, well-drained soil.
Before planting, dig a planting hole and apply basal fertilizer. Planting density is generally plant spacing of 2 - 3 meters, spacing 3 - 4 meters, planting about 110 per 667 square meters (1 acre). The size of the planting hole is generally 1 meter long and 60 meters deep. Basal fertilizer is applied to pigs, cattle, chicken manure and waste manure 20-30 kg per kilogram, compound fertilizer 1 kilogram, lime 0.5 kilograms, phosphate fertilizer 0.5 kilogram. The above fertilizer is mixed with some weeds or green manure and some digging mud. Return to the pit to prepare planting seedlings.
4. Planting a planting seedling at each planting point, planting depth of about 2 cm over the root of the tree is appropriate, and immediately after planting, the rooting water can be soaked.
5. Post-planting management
(1) Timely fertilization Fertilizer before spring, before fruit development, and after fruit harvest. Fertilizer types and how much can be controlled flexibly according to plant growth and development. It can be combined with the top-dressing to strengthen the management, spraying 0.5% - 1% of zinc sulfate in the flowering period, can reduce the pre-harvest fruit drop; in January and February and July, August and September spray 0.4% and 0.2% Boron and 0.05% molybdenum have a good effect on improving the quality of the fruit.
(2) After pruning and planting, the height of the seedling is 50-60 cm, and the branch is cut off to induce branching, leaving 3 to 4 oblique branches as the main branch; when the main branch grows to 30-40 centimeters, a short cut will be made. Provocation branching, preselection 2 - 3 as the deputy main branch, and finally the main branch and the sub-branch branch culture on the results of the branch, the results when the length of 30 - 40 cm when the picking heart can be flowering results.
(3) Pest control The main diseases and pests are anthracnose, aphids, and long-lived cattle, which can be controlled by thiophanate-methyl, omethoate, and enemy-killing pesticides.
(4) The fruit must be bagged during growth and development to increase the product rate. Fruits should be timely harvested and graded and packaged.
