Mastering the essentials to grow good citrus in autumn

"In the autumn, transplanting citrus with mud, we must do our best to reduce the loss of the earth. In particular, we must superficially cultivate the soil. We must cultivate the soil, compact it, and permeate it...." On October 8, the author came to the Ganzhou city. In the village of Shangshi G, Shizhai Town, Yang District, Liu Ye, the head of the township agricultural technology promotion service station, came to Tang Youyu, a villager who returned to his hometown to establish a citrus plantation base for “Qingjian”, and gave on-site guidance on scientific cultivation methods.

Autumn planting time - from mid-October to early November is appropriate. At this time, the inner parts of the autumn shoots are mature and the dry matter accumulation in the seedlings is sufficient. Since the temperature dropped gradually after planting, the above-ground part generally did not germinate, but the soil temperature decreased quite slowly, and it was very suitable for the growth of the seedlings underground. Therefore, new roots can be grown 5 days to 7 days after planting. According to random inspections, after 15 days, the new roots will be about 8 cm to 12 cm long. After 20 days, the new roots can be divided and the new roots can be up to 30 cm long. In the relatively dormant winter fruit trees, the seedlings have basically stood firm. This laid a solid foundation for the second year of vigorous growth, the normal shoots of the new shoots, the increase in the amount of growth than the spring planting about 30% -40%.

Nursery irrigation - Autumn climate is sometimes dry and rainy, especially in mountain orchards. The lack of water sources makes it difficult to increase the survival rate. Therefore, it must be timely irrigation. The first 5 days -7 days before the emergence of irrigation 1 - 2 times, so that the seedlings suck enough water after transplanting seedlings.

Pruning of wounds and leaves - cut the roots of the cuts from 1 cm to 2 cm before the birthing position of the wounds, which will accelerate recovery of the wounds; cut off the leaves of the seedlings from about 1 cm in front of the petioles (cut off one leaf 2 /3 or 1/2), which will help reduce water consumption and increase survival rate (leaves at tender tips should not be cut).

Strictly packing and transporting seedlings - When raising seedlings, first cut off the immature young late autumn shoots, beat the pulp, and bind them with external straw, and the seedlings should be packaged with the seedlings (big seedlings should be packaged as single plants). If the remote transportation should be watering the leaves, otherwise it will cause fallen leaves.

Shallow plant compaction - When planting, the marrying interface appears about 5 cm from the ground. The roots are stretched in the natural direction and compacted compactly by layers of fine soil so that the roots are tightly integrated with the soil. At the same time, we must pay attention to not hurt the roots.

Irrigation Cover - Immediately after planting, pour enough water to make the soil in the planting site drenched. After the surface water is sucked dry, spread a layer of fine soil, then the ground covers the grass, moisturizing insulation, help to improve the survival rate.

Timely dressing - 15 days to 20 days after planting, the diluted manure urine can be poured once. After the spring buds germinate in the coming year, a thin fertilizer is applied every 20 days to promote the growth of new shoots. (The nitrogen fertilizer is generally used within 2 to 3 years after planting to make more shoots and promote the rapid expansion of the canopy. To benefit early yields).

Liu Ye said that citrus is an evergreen fruit tree that can be planted for almost a year. Most fruit growers are accustomed to spring planting. However, the spring planting seedlings is the first to germinate and shoot, and then it takes root. Due to sprouting and shoots, the consumption of nutrients and moisture in the tree body is large, and the nutrients and moisture absorbed by the roots that have just survived cannot be supplied to the nutrient on the ground, which is unfavorable for growth. Therefore, the autumn planting is better than the spring planting.
