Method/step
1
Soil preparation should be selected from fertile sandy loam soil and two-soil soil planting. After harvesting in front of crops, we should eliminate stubbles and plow, plow depth 30 å·¦å³m, and combine them together.
In general, about 5,000 kg of organic fertilizer is applied per acre, and 25-50 kg of phosphate fertilizer or 50 kg of diammonium phosphate is used. Before sowing, the width should be 70-80 mm. Ridge to be broadcast
.
2
Cut before sowing germination cuts 50 per kilogram of potato chips is appropriate. When cutting, first cut them longitudinally and then cut them horizontally to make the cuts uniform in size. Each piece is
There are 1--2 buds. Chopped tubers should be washed several times with well water, and then 500 times 50% carbendazim solution added 1000 times agricultural streptomycin soaked for 15 minutes.
Then remove and dry (preferably within 2 hours) germination. Germination: When the germination period of potatoes has passed during spring germination, just increase the temperature and sow.
In the first 20 days or so, the immersed potato chips are immersed in moist sandy soil to germinate. The temperature is maintained at about 15, and when the buds grow to 2 em, they can be sowed.

Timely sowing, rational planting of spring planting, sowing from the end of February to the beginning of March, harvesting from the end of May to the middle of June, mulching at the time of sowing,
The spacing is 60cm, the spacing between plants is 25cm, or the spacing is 70cm, and the plant spacing is 20em. It is advisable to keep the density between 4000-4500 plants per acre.
4
After the spring planting of field management in spring, the principle of field management is to “first push and then promoteâ€, that is, before budding, try not to water in order to prevent the ground from soaring.
After budding, water and fertilize to promote the growth of underground parts. General mid-April mid-till dressing: 40-50 kg of carbon and ammonia per mu (or 15 kg of urea)
Pounds) into the ditch, earthing and watering from late April to early May, second earthing and watering in mid-May, and watering according to flooding
Keep the soil moist and the ground is dry and wet. It is advisable not to water the l0th day before harvest to prevent the field from rotten potatoes. If plants are found to have a mad trend, they can be in the bud stage.
(in late April, early May) Spray 50-t00 grams of 15% paclobutrazol per acre for control.

Diseases and Insect Pests of Potatoes The main diseases of potatoes are late blight, prevention and control measures. First of all, strict quarantine, no adjustment from the ward; Second, we must do a good job
Potato processing, the implementation of the whole potato whole, you need to cut, you should pay attention to the disinfection of the knife; Third, in the growing season, if there are plants that have late blight, should be sprayed
Drug control, can be used 50% mancozeb WP 1000 times or 25% WP wet dexamethasone 800 times to control. Once every 7 days, even spray 3--4
Times. The pests of potatoes are mainly aphids, 28-star ladybugs, and underground pests. The main control methods are: 40% omethoate 800 times for aphid control or
10% citric acid once (netacloprid) WP 1000 times to control; 28 star ladybug with 80% trichlorfon 500 times or 1000 times dimethoate spray control,
The adults were found to have started to control; the underground pests were mainly crickets, cockroaches and ground tigers. They were treated with 80% trichlorfon WP 500 g and dissolved in water and fried.
20 liters of cotton bait cake or sesame cake or wheat bran mixed as bait, spread on the ground near the seedling root in the evening, or trapped with phoxim granules 812 powder, with sowing
Apply to the soil for control.
