"The cashew is not easy to eat the president's hairpin" hot search, everyone knows what is going on? The fact is that the Sri Lankan president feels that the cashews he tastes are very unpalatable on his flight back to China, so he has to hold the buyer accountable. In fact, this cashew nut is difficult to eat, and related personnel in order to save costs, buy low-cost products have to do, then how to grow cashew nuts? In the end, how to plant it can make the cashew nuts delicious. Let's learn the key points of cashew planting together with Huinong. 1 Growth conditions Generally, cashew nuts are not drought-tolerant, and high temperatures are required during the growing season. The average monthly temperature should be maintained at 23 to 30 degrees Celsius to produce normal results. 2 reproduction The shape of the seedlings of the cashews is usually unstable, so the reproduction technique mostly uses asexual reproduction. The asexual reproduction techniques of cashew nuts mainly include abutment, bud grafting, beading, cutting, cutting, soft splicing, grafting of epicotyls, inlaying, splicing, cutting, tissue culture, and the like. 2.1 sowing and breeding Seeding rate of 30 mg/100 g of indole butyt for 24 hours can be increased by 61.11%. Soaking seeds in warm water at room temperature of 55 degrees Celsius for 24 hours, the seedling rate can be increased by 50%. In addition, soaking seeds with 60 mg / 100 g of tip for 24 hours and soaking with 1/2 adnk for 24 hours can also promote the germination of cashew seeds. Soaking seeds with 90 mg/100 g of naphthaleneacetic acid (naa) for 24 hours has the best effect on promoting high growth of seedlings. 2.2 bead breeding Cashew seedlings should be selected for 2-4 months or October-November, with the highest survival rate of over 93%. The age of the bead mother plant is preferably less than 10 years old, and the root can be rooted 35 days after the beading, and can be separated from the mother tree in 45 days. If the mother plant is older than 20 years old, it is difficult to root after the beading. The material used for the bead is peat, moss and shavings. The mother tree is treated with 0.00025 g/ml of ethylene or 0.001 g/ml of chlormequat before the bead is propagated, and the aerial bead is treated with 0.003-0.005 g/ml of itt and 0.0002 g/ml of p-carboxybenzyl. It can promote the roots of branches and increase the number of roots and root length. 3 tissue culture Cotyledon explants cultured on a medium supplemented with 0.5 mg/L of iaa and 0.5 mg/L kinetin can form organs directly, and complete plants are formed directly after about 5 weeks without further cultivation and induction of rooting of the plants. 4 Cashew Management Technology 4.1 plastic trim Plastic trimming can adjust the structure of the canopy, improve the ventilation and light transmission of the tree, thereby increasing the fruit setting rate and increasing the yield. The principle of pruning of cashew saplings should be light and should not be heavy. It should be done sooner or later. It is a method of pruning several times in batches, and the effect of pyramidal pruning is good. 4.2 Fertilization management Although the cashew tree is resistant to stagnation and drought resistance, the cultivation practice has proved that there is almost no yield of cashew trees that are naturally grown in love. The yield of adult fruit trees will increase exponentially after fertilization. From the perspective of fertilization types, n, p, k mixed application has the best effect. Secondly, p is applied once again, and n and p are mixed again. Higher levels of n can prolong flowering, while higher levels of p and k shorten flowering. Each year, each plant applied n600 grams, p200 grams, k200 grams can significantly increase the individual plant tree, increasing the total yield and the rate of kernel. 5 Cashew disease prevention and control Cashew nuts are endangered by more than 60 pests at different stages of their growth. Among them, cashew disease mainly includes inflorescence blight, stagnation disease, gum disease, branch rot disease, leaf rot, yellow leaf spot, and lobular disease. Pests mainly include cashew horned owls, cashew moths, cashew mites, and chafers. Cashew nut mites are a kind of cashew tree stem pests. The control of the cashew tree stems is best in the 7-month months of spawning. Generally, 0.15% of carbaryl or 0.05% of monocrotophos can be used to treat the bare roots of the cashew trees. The larvae of the scarab mainly endanger the roots of cashew nuts. The method of chemical control is to apply the best ingredient of 1 kilogram of stone sulphur mixture per hectare, and the insect damage is reduced by 74.4% after 15 days of treatment. The above is the whole content of today's cashew planting technology. Farmers who want to know about cashew cultivation techniques can have more views.
