Techniques to lychee fruit
environment
.Soil, soil suitable for growth and yield. Of litchi should be the soil with soil organic matter, deep, including loam, sandy loam. Acidic to neutral, is soft, pH value is spotted. Between 5-6.And should the elevation from sea level more than 400 meters, especially varieties Hong Hyun. Oh เฮียะ Kim Jeng and breed emperor
.Air right of its growth and flowering and fruit set of litchi should cool air in the winter season. The ratings and air operators in the business is lower temperature 40 degrees Celsius. And in the first flowers to low temperature than 15 degrees Celsius.50 hours or less than 10 C no less than 50 hours when the temperatures are high up on the fine, but if too high 40 degrees Celsius. Will yield, dry and crack
.
the moisture in the air. Relative humidity at the most suitable for lychee, 2 phases moisture in before flowering should lower than 80 percent and the moisture in the 80-100%
preparations plantation
.The watershed area, which is the need to raise the grooves. Should be raised to the width of the convert at least 6 meters deep groove 1 meters wide 2 meters to the drain to the rainy season and the season and retention, but
.Upland area don should adjust the smooth to facilitate the operation if the area has a slope, more should be prepared, along the ladder rack. Or leveling the planting hole
.Spacing, lychee, spacing between 8X8 meters to 10X10 meters in the area raised groove size of grooves are forced term on 8 meters. In the upland area spacing based on the soil fertility, bad soil plant frequency soil deep son 2002
how to grow
.Hole preparation plant. The watershed should set holes in the straight line on the plot size wide, long, deep, about 50-80 cm and organic fertilizer. "The ogre" formula 1 (gold bar). 0 rate.5 kg per hole, or about 2-3 clasp. Mix well and cover into the hole by hole than the original soil in soil around 15 cm. The upland area to dig a hole in the straight, wide, long and deep around 50-80 cm.
preparations branches varieties. Should prepare the cuttings at 2001 al operating performance times 2004 loans in prescription in healthy set ratings and its. The culture in the greenhouse. Before the transplanted
.Preparation of wood and the main support shade. Main wooden bamboo bamboo or wood, support a strong ผ่านศูนย์กลาง diameter less than 1.5 cm long and less than 150 cm shade used a shed or the falling leaves, such as coconut leaf shading on the East and West
how to grow
.The branch of prepared down the central hole. If the container with the culture decays, difficult, such as plastic bags, or the pot must be brought out of containers branches seed before planting. Planting should light the plant level is equal to win ground level in the converter.Firmly press after the main wood prepared park near to the branches, breeding and tie a rope to the upright support covered by a shade. Water
.Practice of care after planting
.Irrigation time after planting to match the rainy season. If the heavy rain should do the drainage, and check the hole planting. If the ground subsidence basin water locked to an embankment. But if the rain should water soil moisture content is always
.Prevention of disease and insect
in the bud, should check and injection of chemical remover โรคและ insects that destroy the leaves of weed control
.Control of weeds using dig tag removal or cut, refrain from using chemical weed Because be affected with the root litchi. The chemical spray could destroy the litchi. To make the initial growth and yield of low
.Cutting period งกิ่ง
.Should treat a central stem only one plant and the first branch of the high ground around 40-80 cm and pruning dry branches is branch dew. Small branches inside the canopy receive branches cross.Planting windbreak
in windy sources should be prepared for planting windbreak before considering
2 1. Wind direction. The wood type wind to grow to grow fast. Branches less high, durable to the environment, especially wind resistance as well as bamboo pole
3.Grow away from the row of lychee, at least 6 m
4. Planting windbreak planting 2 row, one by one, and ควรปลูก wood wind before planting lychee 1 years. At a minimum, the wood wind how many line depends on the length of the park with the height of the wood wind
.Practice of water 1 care
. Litchi was 1-3 years in dry season water regularly, at least once a month 2-3 (weather)
2.Litchi stem yield and water in the dry season to regularly, at least a month at 3-4 times but ในช่วงเดือน November before flowering should refrain from giving water. If the rain to make the drainage from the plot.To stress the lychee (help bloom easier) in before flowering. After notice start flowering characteristics of canine small. Around 50 percent should start water, increasing the amount of water and the water in the canopy. The 2 times per week. And should refrain from the water before the harvest 7-10 day
.3. The quantity of water to each time depends on the type of soil, the size of the canopy, and how its profitability irrigation method water
3.1, south water surface. It is an elevated groundwater to rise to the level of the roots can absorb to use, such as lifting groove plant, etc. this method is suitable for the area group.River)
3.2 irrigation on the soil surface is to let the waterlogging or let the flow to the surface. The water that must adjust to smooth and slope slightly (about 2%) water by use สายยาง pumping. From water and drag the hose on by trees.Not suitable for areas with irrigation water less
.3.3. Water sprinkler (Springer). As the water through the pipe with pressure water spray and spray head injection area. The canopy. This will save its than giving water.
