The experience caring cashew tree
The loss of the season is mainly due to the flowering plants when flowering flowers should be rotten fruit can not bear fruit. To take good care of the orchard Post-harvest and to mitigate the weather-related hazards while flowering, we must first know the weather in the year through the meteorological and hydro-meteorological stations in the area. The purpose of this is to proactively determine the end of the rainy season, thereby influencing the technical measures that govern flowering. Flowering does not (or is less affected by rain). When catching the weather we proceed to fertilize the tree, here should use the root fertilizer and foliar fertilizer.
Fertilizer roots should be applied in two phases
+ Stage 1: After pruning, creating canopy, we use fertilizers to restore the trees after harvest (from May to June): NPK fertilizer application rate of 3 Protein + 4 Lan + 1 Potassium.
+ Stage 2: Depending on the time of the end of the rainy season (best before the precipitation 2-2.5 months), fertilizing at a rate of 1 Nitrogen + 1.5 Kali.If the flat and rain beams can spread stool. On the surface, if the sloping soil is used to fertilize the hole (as many holes as possible) to limit the washout and increase the efficiency of the use of excrement. When fertilizing the first phase should combine the foliar fertilizer for the tree by spraying on the leaves, often using fertilizer with NPK content of 30-10-10. If the orchard is weak we use the NPK content is 20-15-15 or 15-15-15. After fertilizing the second round about 1-2 weeks, if the orchard is still green we use leaf fertilizer without nitrogen but rich in Lunar and Potassium (MKP product) so that leaves accumulate Lan and potassium to accelerate aging. , Increasing the flowering of shoots in plants.
Before rain 50-55 days we spray 99% Thiourea to make leaf fall in bulk, prepare to sprout and cotton, 2-3 weeks after the flower buds. About 20-25 days later, continue to provide NPK foliar fertilizer ratio is equal to the flower and flower petals long to help the flowers easy to pollinate. At this stage, farmers can use Bortrac to spray against cotton loss and fruit loss; Use HK 20-20-20, Super humic to spray cotton, nutritious, combination spray disease prevention. Normally in early December the fruit is safe.
When catching the weather situation, we apply fertilizer to the tree, use the root fertilizer and foliar fertilizer. Fertilizer roots should apply two times:
+ Stage 1: After pruning, creating canopy, we use fertilizers to restore the trees after harvest (from May to June): NPK fertilizer application rate of 3 Protein + 4 Lan + 1 Potassium.
+ Stage 2: Depending on the time of the end of the rainy season (best before rain 2-2.5 months). Fertilizer according to the ratio of 1 fertilizer + 1.5 Kali….
