Transplanting techniques of Citrus seedlings

Transplanting techniques of Citrus seedlings

In line with the principles of industrial efficiency, product safety, resource saving and environmental friendliness, when building new citrus orchards, we should choose areas with convenient transportation, close to water sources, and access to electricity, water and access. The road covers the whole garden, and the grid layout can be realized, and the road should be solid. The elevation of the park is less than 400 meters above sea level, mountains, gentle slopes and flat land are available. Citrus has strong adaptability to soil and can be planted after all kinds of soil improvement. The mountain garden is built in accordance with the principle of "wearing a hat" at the top of the mountain, "wearing boots" at the foot of the mountain and "planting fruit" on the hillside, that is, it does not destroy the natural forest belt and vegetation on the top of the mountain, and the forest area is set aside at the foot of the mountain to protect the fruit planting area on the upper waist, which can effectively ensure the balance of natural ecology.

The seedlings of citrus seedlings should be non-toxic, disease-free and healthy nutrition cup seedlings, and the grafted seedlings of Fructus Aurantii should be recommended. The planting row and plant should be determined according to the topography, if it is planted in the mountain, it should be planted horizontally around the mountain, and a gradient drop is formed between the rows. Each row of citrus is planted in the shape of "product", and the width of each ladder is 3 meters or 6 meters. The plant spacing is 2 meters; the planting pit specification is 60 cm × 60 cm × 40 cm, and 111 plants can be planted with high yield per mu. If you are planting in the field, you must get up the bed and dig drainage ditches. The planting pit is located in the middle of the border, and the planting pit is located in the middle of the border. For the land with good drainage, the plant row spacing is 3 meters × 3 meters, or the plant row spacing is 2.5 meters × 3 meters, the furrow spacing is 6 meters, and the planting pit size is 60 cm × 60 cm × 40 cm. 88 plants can be planted per mu. The citrus planted before the Spring Festival can achieve 3-5 shoots. The citrus planted in the autumn of September and November can achieve 4-6 shoots in the coming year.

For the newly planted mandarin seedlings, we must fully apply organic fertilizer, thoroughly improve the soil to make a good foundation, ensure that the two shoots in the coming spring, apply sufficient base fertilizer, at the same time, at the bottom of the planting pit, apply 5 kilograms of bio-organic fertilizer and soil to form a funnel layout. After planting the seedlings, 40-50 cm away from the trunk, and then spread 0.5 kg of Happy soil Fu'an and other biological organic-inorganic special fertilizer, sprinkle a circle. It is appropriate to cover soil 3cm to 5cm thick.

If you are transplanting seedlings, you must choose uniform, non-toxic and strong seedlings, remove the cup membrane, straighten and plant them back to the soil, and gently lift the seedlings up when the soil is halfway back (nutrition cup seedlings do not need to lift seedlings). Then continue to return to the soil and compacted to 2-5 cm below the marriage interface, using soil to build a tree plate (30 cm high, 60 cm in diameter), each plant poured through about 15 kg of root water. What we should pay attention to is: 1. The film at the interface should be cleaned. two。 Returning to the soil can not cover the marriage interface, which should be more than 3 to 5 centimeters from the ground. 3. When covering the soil of the seedlings, step on the surrounding soil, do not trample on the roots of the seedlings. 4. When watering, pour in slowly. 5. If covered with black film, do not close to the trunk, maintain a distance of 1 cm to 2 cm, do not hurt the leaves.
