Walnuts have the meaning of supplementing the brain, because it is very nutritious, and it is quite delicious, so many people like to eat, so how to grow walnuts? Next, Xiaobian will share with you from these aspects. First, the growth habits: (1) Growth habits Walnuts are deep-rooted fruit trees. The 1-2 year old saplings are vertical root growth stages, the growth of the shoots is slow, and the vertical roots grow fast. After the third year, the number of sides has increased sharply, expanding to the periphery, entering the horizontal root growth period, and the growth on the ground is accelerating. (2) Result habits Flowers: Walnuts belong to the monoecious plant, and the wind coal flower. Flower and differentiation: Pregnancy walnut female flower mixed buds can form female flowers, male flowers and lateral leaf buds are homologous organs, which are later extended into inflorescences, and later used as pollination. Fruit development: from the stigma of the stigma to the total sputum to yellow cracking, nuts mature. Falling flowers and fruit: caused by poor fertilization, malnutrition, and low temperature and drought during flowering. Walnuts are lighter, and the fruit is about 10-15 days after flowering. Second, plastic trimming technology: It mainly adopts the small crown to evacuate the layered tree shape (the center is dry and upright, then choose 2-3 adjacent branches in different directions as the first main branch, the base angle is about 60°, and the second layer is selected in 3-5 years. There are 2 main branches, the spacing between the upper and lower layers of the walnuts is not less than 1.5-2.0m, and the early walnuts are 0.8-1.2m. For saplings, mainly the cultivation of the main and side branches. The pruning of the result tree is mainly to adjust the proportion of branches and flowers, use the heterogeneity of shoots and the direction of shoots, adjust the relationship between nutrition and accumulation and distribution, and use different degrees of pruning to balance the tree potential. The pruning of old trees can be divided into small updates and large updates. The small update is generally to retract from the upper part of the main side branch to retain the healthy and strong branches, and to reinforce the lower branches of the cut. Large updates are generally truncated in the middle of the main branch. Promote new branches, choose branches with good directions to make branches. Third, harvesting and post-harvest handling: Picking time: Walnuts generally have 10%-30% of the green peels on the tree, which can be cracked mainly by bamboo sticks. Treatment method of green skin: Traditionally, the method of stacking is used to peel the skin, that is, the thickness of the green fruit is about 50cn, and the pile of grass covers 10cm thick grass or leaves to raise the temperature. Usually 3-5 days with a wooden board to hit gently to fall off, but the walnut fruit surface has a small amount of stains, affecting the sense of buying. There is also a chemical treatment method, which is soaked for half a minute with a concentration of 300-500 mg/kg of ethephon solution, and then deposited according to a thickness of 40 cm, a temperature of 25 ° C, and a relative humidity of 80% - 90%. You can molt in 2-3 days. Sharing the cultivation techniques of walnuts is here today. I hope to provide some help to you.
