Before planting corn need to be prepared soil. To weed And physical properties of the soil. A ventilated In addition, soil preparation, soil moisture is better with preparing the ground for the first time. Should begin immediately after the harvest. The incorporation originated cob of corn. To rot in soil in the future. Soil preparation must be done again. Corn in the close season following plowing should be done after the rain, about 1-2 times should plow in regular furrows for the second time to plow roughly for the first time and each one was about 15 cm deep plowing and soil preparation in the land should not be too wet. To make the soil compact. Not suitable for the spread of maize roots. In the final slope should plow across the slope. To prevent soil erosion, surface preparation equipment used to plow the soil with native species such as the use of animal traction force. And walking tractor engine. The current widely used tractors For a quick and easy Plowed deep and drown parts. The plant has a better plow drawn by a land animal to use tractors and harvesters must be adjusted to a minimal stump. It is compact, convenient
third. How to plant corn should be planted in rows. In order to facilitate the healing practices such as plowing between rows of about 35-100 cm distance between holes 25 cm sowing corn into a hole depth of approximately 5 cm 2-3 seeds to germinate the seed. When germination should withdraw the remaining holes per tree. If grown by this method are approximately 6000-8000 of the maize plants / ha, despite the distance between holes 50 cm may be subject to change by adding a second / early hole, which generally are not popular and peasant withdrawal. split It consumes a lot of labor costs. Planting time is 2-3 drops seeds into the hole and do not withdraw them separately throughout the growing season to grow rapidly, or how much of it away. Based on the condition of the soil If a new forest land with high organic matter. Should grow more frequent May grow up to 12,000 hectares of tree planting or spacing, so the rate can be adjusted to suit the specific local conditions of the sowing can be done in several ways, such as using wood as a hole drills. Then, using hoes to dig the track drills. Or handling equipment should be tested before planting the seed first. If low germination rate Drills should be enough for them to germinate, as if there were only 80 per cent to 2 per tree planting hole should drop to 3-4 seeds per hole practice to maintain one. Improves the fertility of the earth , if forest land is opened. And the fertility of the soil is high. Fertilizer is not necessary When planting corn consecutive 4-5 years should begin to improve the fertility of the soil it. May put manure or green manure science was cultivated legumes, such as Crotalaria (Crota laria juncea) and Jason Taiwan (Sesbania swsban) for incorporation into manure. How to add organic matter And food crops in the ground are good and economical way. If your cattle manure per acre with about 3-4 / year is better for the scientific use of fertilizers. In a typical maize growing areas To use fertilizer containing nitrogen (N) and phosphorus, about 8-16 kg / ha of potassium and approximately 4-8 kg / ha for the duration of the fertilizer. May all mixed fertilizer before planting. Or half the total nitrogen, phosphorus and potassium fertilizer before planting. Then nitrogen half. When the corn was about 2-3 weeks 2. weeding weed is a major pest of corn. If the soil is poor preparation Weeds will compete in the land of corn results can not be fully realized. Weeding It should be done at least one time after the transplant may be used to plowing between rows to hoe or grazed it. The chemicals were atrazine (atrazine) sprayed before planting corn germination of weed control that well. How to use genuine medication is thawing 500-1,000 g / L 40-80 throws in a one hectare area before or after planting is complete, however. Herbicides are more effective when there is moisture in the soil only three. Prevention and eradication Insect pests of corn maize with severe disease are Mildew (downy mildew) is already domesticated rice will not produce any chemicals present, no fungus species. To prevent this, Screening for this disease resistant maize varieties only. Corn other diseases No violence in Thailand insects that destroy corn is severe grasshopper locust (Patanga succincta L.) creatures to destroy the maize seedlings to early to start off the pod. May be eliminated by using dieldrin 2% powder sprayed at a rate of 5 kg / ha or if the drug dieldrin liquid. 50-100 grams genuine drug use meat mixed with water at the same rate. Also spray locust larvae live. And spaced spray 7-10 days to harvest and storage of corn is ripe. And harvested When the pods are straw-colored jacket. Best way is to let them in converting corn to dry well before. To float in Tak And easy to maintain On average corn varieties grown in Thailand. From planting to harvest the devil between 90-120 days to harvest corn farmers who want to use the store. By deducting the pods dry and then leave early. Lamb pod shell out Or to shell out the back. Using energy-saving harvest corn, there are very few in the country. This is because the equipment is expensive And low work efficiency. The varieties that farmers grow a height. And unequal pod In addition, beginning to break down, too.
