What Month Is Best for Planting Walnuts? Suitable Growing Regions in China and High-Yield Cultivation Methods
Walnuts are rich in nutrients and have traditional Chinese medicine benefits such as “replenishing qi and nourishing blood, moistening dryness and resolving phlegm, and warming the lungs and moistening the intestines.” They are one of the world's four major nuts, and the market is very broad. So in which month can walnuts be planted? Which places in China are suitable for growing walnuts? How can they be planted for high yields?
1. In Which Month Can Walnuts Be Planted
Sowing can be done in autumn or in spring. Here, we take spring sowing in mid-March in the Baoding area of Hebei as an example. Before sowing, soak the seeds in clean water for 4 to 6 days. When the seed shell cracks and the white tip shows, they are ready for sowing.
On a leveled seedbed, open sowing furrows at a row spacing of 40-50 cm, with a furrow depth of about 15 cm. Sow by the dibbling method. When dibbling, be careful to keep the seam line of the seed parallel to the sowing furrow. The end showing the white tip is the future root of the seedling, and this end should face downward when sowing. The sowing depth is best when the upper end of the seed is 3 to 5 cm below the soil surface, and the plant spacing is 10-15 cm. After sowing, cover with soil and rake the ground level. To ensure emergence, water once after sowing.
After sowing, germination and emergence begin in 15-20 days, and the seedlings are fully emerged in about 30 days. To promote seedling growth, strengthen water and fertilizer management. Topdressing should be mainly nitrogen fertilizer, such as urea, applied in furrows at 10-15 kg per mu. Irrigate after topdressing. The irrigation amount should be based on soaking through.
2. Which Places in China Are Suitable for Growing Walnuts
Northwest China, North China, the Qinba Mountains, the Jinsha River basin, and the western Sichuan Plateau are all very suitable areas for growing walnuts, and the northwest region in particular is best for developing walnuts.
China is one of the places of origin of walnuts, and walnuts have been cultivated for more than 2,000 years. Now, except for Heilongjiang, Shanghai, Guangdong and Hainan, all other provinces, municipalities and autonomous regions across the country cultivate them.
3. How to Plant Walnuts for the Highest Yield
Selecting and promoting excellent varieties and scientific cultivation management are the best approaches, and also the general trend for walnut development in the future.
1. Orchard Site Selection
The orchard site should preferably be wind-protected, sunny hilly gentle slopes, flat land, or well-drained ditch flats. The soil should preferably be loam and sandy loam with good water retention and aeration and a pH value of 7-7.5. Avoid planting walnuts on soil where willow, poplar, or pagoda tree has grown, to prevent root rot.
2. Planting Method
Before planting, first fill the pit with topsoil mixed with fertilizer, then place the seedling into the pit, spread out the root system, and firm the soil while filling. Keep the main trunk of the seedling vertical. Finally, keep the root crown about 5 cm above the ground, and mound soil 5-10 cm above the original ground level. Then water thoroughly, and after the water seeps in, seal it firmly with soil. Finally, spray with xingaozhimo to preserve soil moisture and raise temperature, improving the survival rate of the planted seedlings.
3. Post-Planting Management
(1) Check survival status and replant. After the buds unfold leaves in spring, promptly check the condition of the planted seedlings, replant seedlings of the same variety in time for plants that have not survived, and use plant electronic fertilizer, using the high-energy electrons released by the plant's own photosynthesis and the principle of plant electronic polarity induction to improve cell division, molecular synthesis and nutrient matching and digestion levels, accelerate the frequency of metabolism, and activate the plant nutrient transport system to produce effects beyond fertilizer efficacy.
(2) Trunk determination for young trees. For young trees that have reached the trunk determination height, determine the trunk promptly after sprouting. The trunk determination height for early-bearing walnuts is 1-1.2 m, and for late-bearing walnuts 1.2-1.5 m. After trunk determination, apply guoshu shuashen jingling to the tree body, which can make trees bearing more fruit stronger in the trunk and increase their load capacity (trunk strength). It can regulate nutrient flow. It prevents soil-borne pests and diseases from climbing the tree to cause damage, cuts off the supply and transport routes of nutrients to pests and diseases on the tree, and depletes the source of disease.
(3) Fertilization and irrigation. After planting, irrigate promptly according to soil moisture conditions. In spring and summer, apply an appropriate amount of chemical fertilizer along with irrigation, mainly nitrogen fertilizer in the early stage and mainly phosphorus and potassium fertilizer in the later stage. After fertilizing, use guangmo yingyang momo in combination, a compound film that enhances the energy-producing nutrients of photosynthesis and chlorophyll, is a high-grade environmentally friendly plant fertilizer for increasing fertilizer, yield and color, thickening leaves, and strengthening stems. It can help plants absorb large amounts of light fertilizer, light energy and light, is compatible with conventional fertilizers, and supplies nutrients for plant growth and development to the limit. One application benefits the whole year.
(4) Use zhikong cuhuawang to intelligently regulate the nutrient matching of fruit tree growth, fill the vacuum of missing nutrient elements, bidirectionally regulate the balance of flower formation in on-year and off-year cycles (promote more flowers in off years, control and reduce flowers in on years), inhibit excessive shoot growth and force surplus to flow back to the fruit, and improve fruit expansion. The method of use is simple and safe, does not damage the tree's vitality, has low orchard input cost, and is pollution-free.
(5) Disease prevention. Plant cell immune factors can be used to improve plant stress resistance and can cause viral DNA to break and die. With strong immune function, it induces interferon and active cytokines, inhibits residual virus replication, and promotes positive-energy ecological growth of plants. Based on the disease resistance mechanism of host plants and the principle of using pathogen virulence variation, it controls the reproduction of physiological diseases and infectious diseases of plants.
