How to achieve high yield in walnut planting? Introduction to the high-yield cultivation techniques of walnut
Farmers who plant walnuts hope that their own walnuts can produce more benefits for themselves, so what are the precautions and cultivation techniques for their own walnuts? The following Huinong.com Xiaobian has compiled the high-yield walnut cultivation techniques for everyone! 1 Building and planting 1.1 Garden selection Walnut trees can adapt to a variety of harsh natural environments, as long as the annual average temperature of the garden is above 9~16 °C, and the annual rainfall of 800mm or more can be planted. In the choice of soil, the soil with deep and fertile soil, strong water retention and well-drained land is more suitable. Walnut sex is sunny, the lighting conditions must be sufficient, so when you build a garden in the mountains, you should try to choose the south slope. 1.2 Variety selection Different walnut varieties can adapt to different soils and natural conditions. Only by selecting the corresponding varieties to graft the seedlings and building gardens according to the actual situation can we achieve the purpose of good quality and high yield. If you want to introduce good varieties from other places, you must first test the seeds and make a good investigation record. The variety can adapt to the local environment and can be planted in large areas. 1.3 Planting The seedlings should be planted as much as possible. The roots of the seedlings should be taken with the mother soil or the mud, and the “three burials and two steps†should be done. After the planting is completed, the tree trays are repaired and the membrane is watered. If you want to make efficient use of the land, you can also implement inter-fruit grain, but you need to leave a 1.5m ventilation belt, so that you can achieve early results and high yield. After the grafted seedlings are finished planting, the results will be 2~3 years, and the high-yield period can be entered in 4~5 years. At present, the dense planting of 3m×4m is the best. Walnuts are monoecious, so, in order to get the maximum yield, it is best to plant in large scale. Walnuts are most suitable for planting from September to November or before germination, and prevent drought and prevent dead seedlings after planting. 2 Soil management 2.1 Deep turning soil, cultivating weeds In order to ensure the efficient survival of the seedlings, organic fertilizer must be applied after planting, and the walnut garden should be deeply soiled, loosened and weeded to prevent soil agglomeration and increase soil permeability. Moreover, on the basis of frequent weeding and weeding, the garden will be turned over once or twice a year. If it is a hillside dry land, it is inconvenient to plow, and it can be carried out 2~3 times in the spring, summer and autumn seasons. The spring is carried out before the germination, and the summer and autumn are carried out after the rain. At the same time, the weeds are buried in the soil in combination with fertilization. This reduces weeds to consume nutrients and moisture from the soil. 2.2 Fertilization and watering The main constituent elements of walnuts are nitrogen and potassium, and nitrogen is more than potassium. Therefore, proper application of nitrogen fertilizer can significantly increase the yield and quality of walnut. Fertilizers should be added to different soil conditions, such as phosphorus and calcium in soils that lack phosphorus. Top dressing should adopt the principle of thin application, start topdressing after germination of young trees, fertilize once a month, base fertilizer should be applied once at the end of September, to the second to fourth years, in March, June, and August of each year. A total of 4 fats can be applied in October. Water must be poured in time after fertilization. 3 plastic trim 3.1 Young tree pruning When the walnut seedlings grow to a certain height, the young trees need to be trimmed and shaped, because it is generally mechanized, so the fixed dry height is generally 1.5m. Because of the strong trunk of the walnut, the trunk is sparse. The general shaping method is: dry height is 50~80cm, but it is not pruned in the year of planting. It only needs to straighten the trunk and protect the top bud. After waiting for it to germinate, it will be used as the center. The important point is to avoid damage, it is best to trim during the dormant period of the walnut tree. 3.2 result tree pruning The walnut tree is still pruned after entering the fruiting period, because the walnut tree continues to expand after entering the fruiting period, and the result is increasing. At this time, the branch group pruning method of “putting the back branch, leaving the oblique branch and the back branch†can be used to cultivate the complete branch group, pay attention to the pruning of the auxiliary branch and the long branch, and timely dispose of the back branch. And drooping branches. 4 Pest control 4.1 Walnut powdery mildew Walnut powdery mildew is a common disease of walnut trees. It usually develops from July to August. In the early stage of the disease, the leaves are green or yellow spots appear. In more serious cases, the leaves will shrink and a round white powder layer will appear. In the later stage, it will be in the Brown or black grain spots are produced in the white powder. Control methods: (1) Continuously remove diseased leaves, diseased branches, and intensively incinerate; (2) Use 0.2~0.3°Be stone sulphur mixture at the beginning of the disease in July. 4.2 Walnut Lifting Moth Walnut limb moth is a common pest of walnut trees. It occurs 1~2 generations a year. Old mature larvae are overwintered in deep soil or weeds, stones and dead leaves, and become sputum from June to July. Spawning at the junction of the two fruits or on the petiole, the period of maximum fruit loss in August. Control methods: (1) Kill the wintering insects, often plowing the tree in the autumn; (2) Shallow the tree tray in the first half of April, and spray 25% phoxim emulsion 3000 times on the top (3) In mid-June, the larvae is in the fruiting stage. At this time, it can be sprayed with 50% parathion 1000 times liquid or chlorpyrifos 2000 times liquid. Spray once every 10~15 days, even spray 2 times. 5 timely harvest The sign that the walnut is fully mature is: the peel is greenish and yellow and cracks or falls off on its own, and the shell is hard and yellowish white. After the harvest is completed, the fruits with green skin will be piled up, piled up to about 50m, and covered with mats and other shades. After 2~5 days of stacking, peel off the green skin and bleach it into lime water or bleaching powder. After drying in the shade, the package can be sold. In fact, in general, in the high-yield cultivation of walnuts, it is necessary to do a good job in building gardens and planting, soil management, plastic pruning, pests and diseases, and timely harvesting, in order to create a good economic value of walnuts.
