Experience Sharing on Raising Jujube Sucker Seedlings by Returning Them to the Nursery
Using jujube sucker seedlings from jujube orchards and returning them to the nursery is a widely applied method for cultivating strong jujube seedlings. (1) Land preparation: choose flat loam soil with a water source as the nursery. Plow deeply 20 cm and apply sufficient farmyard manure as base fertilizer. Make beds 90 cm wide and 10 m long, oriented north-south, with 2 rows of seedlings per bed.

What are the control methods for nutrient deficiency diseases in citrus
Zinc deficiency causes mottled leaf disease. Citrus mottled leaf disease is a common disease, with the typical symptom being mottled small leaves. When new leaves begin to turn green, the main veins and lateral veins appear markedly green, while the remaining tissue is light green to yellowish white and glossy. In severe cases, only the area near the main vein or thick lateral veins is green, and the new leaves are narrow and mottled, mostly upright, with short internodes and clustered branches. Mottled disease is caused by zinc deficiency. Many soils are deficient in zinc, such as soils formed from granite, gneiss, and serpentinite, which contain little zinc; acidic sandy soils lose zinc easily; in alkaline soils zinc readily forms insoluble compounds, thus causing zinc deficiency. In addition, soil that is too dry or too wet, low humus content or excessive application of organic matter, which hinders contact between roots and soil, as well as heavy pruning, all make zinc deficiency likely to occur. Foliar fertilization can achieve fairly good results in controlling zinc deficiency. It is advisable to spray 0.2%-0.3% zinc sulfate solution (with an equal amount of lime) once during the tender shoot stage, and spray 2-3 times for severe zinc deficiency.</p><p></p><p>Copper deficiency or boron deficiency causes dieback disease. In the early stage of copper deficiency in citrus, new shoots are long, soft, and slightly curved, the leaves are large and dark, and fruiting is low, so it is easily mistaken for excessive vigor. In severe cases, the tips of the shoots turn tea-brown and die, short weak clustered branches appear, and they dry out and drop early and gum exudes; when the branches mature, the wounds are reddish brown, and parts of the leaves are reddish brown. Citrus has a very small copper requirement, and ordinary spraying of Bordeaux mixture is already sufficient. However, copper deficiency is likely to occur in peat soil, acidic sandy soil, soil with high organic matter content, as well as on abandoned grazing land and abandoned cemetery land; excessive application of barnyard manure and phosphate fertilizer also causes copper deficiency; newly reclaimed citrus orchards that have not been sprayed with Bordeaux mixture or other copper preparations for several years are prone to copper deficiency. Boron deficiency in citrus: the growing points of buds die continuously, forming clustered buds; leaf veins swell, become corky or split; the fruit is small and deformed, with thick hard peel, and brown resin deposits are present in the fruit center and spongy layer. Boron is easily lost from acidic soil, hence boron deficiency. In soil parent materials such as granite, gneiss, and schist, boron content is extremely low; in alkaline soil its solubility is poor, so boron is also deficient. Excessive application of phosphate fertilizer or lime, or soil drought, all affect the availability of boron and the absorption of boron by roots; sour orange has weak boron uptake, so citrus grafted onto sour orange rootstock is generally deficient in boron. For copper deficiency, Bordeaux mixture or other copper fertilizers can be sprayed. To supplement boron, soil application can be used, or 0.05%-0.1% boron fertilizer solution can be sprayed at the bud stage, flowering stage, and small fruit stage.</p>
