Plastic film cover cultivation

Oystercatchers, also known as taro, fall, underground tubers for consumption. In the production, the common pods produced in the first year are used as seeds. After growing for a certain period, the pods increase to become the female quail in the current year, and the pods are divided on the pods, and some pods can be further separated from the pods. Different breeds of mother-in-laws have different abilities and different capacities. Some mothers have larger heads, and their sons have less ability to pick up grandsons. Some mothers have smaller heads, but they have different children and grandchildren. He has a strong ability.

Sorghum conventional cultivation from the sowing on March 10 to October 15 harvest, takes about 215 days, of which sowing to the emergence of about 50 days, emerged to about 85 days of red peony. In the same period, the scented lotus root was planted with a mulching film and it took about 180 days from sowing to the market of Qingshentou. Among them, about 40 days from seeding to emergence, about 60 days from emergence to scab, mulching can be over 30 days earlier than conventional cultivation, and can be listed 20 to 30 days earlier. The price per kilogram is 0.4 yuan higher than conventional cultivation. , Mu gain more than 300 yuan.

Non-pollution and high-yield cultivation techniques

Soil-fertilizing, fertilizer-favoring, drought-resistance, and planting require flat terrain, low groundwater level, deep tillage layer, high fertility, strong ability to retain water and fertility, and convenience for irrigation and drainage. It is best that no one has been planted for 2 to 3 years. Dry land for the field. From mid-December to the end of January, the land will be ploughed to a depth of 30 to 40 cm, and the soil will be frozen and thawed. In mid-February, 4000 kilograms of arable and livestock manure per acre were applied. In late March, 25kg of 45% potassium sulfate compound fertilizer was used per acre, and the soil was finely ground to fully mix the fertilizer. At the end of March, three trenches (field vertical trenches, horizontal trenches, and extra-field trenches) were excavated. They were made of rakes, hoe widths (including ditches) of 4 meters, sulcus width 20 centimeters, depth 15 centimeters, and 6 lines per pod.

Select the seed of the sun at the end of March and take out the entire winter planting culm pods, select the pods with the characteristics of the cultivar as seed, require the top buds to be healthy, disease-free, no insect eyes, no injury spots, no frost damage, strong viability. The pods are in the shape of a snowberry. The pods weigh about 50 grams each, and they are stored separately in size.

Appropriate sowing in early April, the temperature rose to above 10 °C, 5 cm above ground temperature above 12 °C, seize the cold tail warm head or cloudy tail sowing. Strip the sweater on the block before broadcast. Planting spacing 50 cm, row spacing 65 cm, 2050 per mu. The upper part of the sub-palm is required to be aligned and the earth-covered thickness is about 8 cm. After sowing, each acre with 50% acetochlor EC added 80 kg of water spray, 1 day after the cover film moisturizing temperature. Immediately after the emergence of the seedlings, the seedlings were broken and filmed. 80% of field seedling research labs fill the gaps.

After 1 month of fertilization and water management, seedlings were fertilized, and the yellowing of the seedlings was yellowed by applying 5-10 kg of 45% potassium sulfate compound fertilizer per acre. In mid-June, when the seedling height is about 40 cm, the balance of seedlings is observed and balanced growth is promoted. A 45% potassium sulfate compound fertilizer is applied at 10-15 kg per acre. In the middle of July, tuber inflated period applied 45% potassium sulfate compound fertilizer 15-20 kg per mu. In the middle and late July, the soil should be properly watered when it is dry so as not to affect tuber enlargement;

Straw grass roots can be divided into two. For the first time, when the height of the seedling is 60 cm, take the water grass or the decomposed stalk roots, the height is 7-9 cm. The second time before the closure of the line (plant height 80-90 cm) roots with water or straw, height 8-9 cm. Remove field weeds in a timely manner.

Pest control diseases mainly include diseases such as epidemics and spoilage; insect pests include cockroaches and spider mites. Most of the diseases occurred in June-August, and there were concentric ring patterns on the lesions of the leaves at the time of onset and perforation later. Generally in the beginning of late June, medication, spraying with 72% sulfuric acid streptomycin sulfate 4000 times or root, connection medication control 3 times, every 7-10 days. For the prevention of earthworms, in late July to August, combined with drought-resisting water to kill young larvae, or 90% trichlorfon 4000-8000 times watering, pouring 300 ml per hole.

Timely harvest in mid-October, the dragon head dragonfly matured, dig out the sun for 2-3 days, drying soil attached to the top of the taro, in addition to the whole cellar storage used for seed replanting, the spring excess size classification.
