How to pot pot amaranth? Potted chives planting technology

1. Selection of nursery sites

The nursery site selection is certified by a pollution-free production base. There are few industrial and mining enterprises around, and there is no pollution in water, air and land. Daejeon, which has not been planted for many years without chemical fertilizers and pesticide residues, is used as a nursery site.

2, nursery

At the end of April, seedlings were planted in a small arch shed, and the variety was dominated by Jiuxing No. 10, which did not sleep. (1) Do it. In the deep ploughed land, the rafts are 20m long and 1.5m wide, and one acre of leeks needs to be made of such cockroaches; (2) fertilization. Spread the soil residue 300kg evenly on the seedbed, then turn it over again, mix the loam thoroughly, and then level the land; (3) watering. After sprinkling the fertilizer, water the water, and then use the wooden board to level the ground after the water has been infiltrated, so that the bed surface is flat and there is no water; (4) sowing. After the water is completely infiltrated, it is sown on the seedbed, and the seed is planted with 5 kg, evenly spread in the two wells, and then covered with 1-1.5am of fine sand; (5) buckle film. The arch is made of 2m long bamboo piece, about 70cm, and the mulch with a width of 2m is covered. The tension of each neutral cable is tight, and the earth pressure around the film is tight.

3, seedbed management

The surface of the bed is poured with the dry, keeping the surface of the bed moist to facilitate emergence. After 7-10 days, about 30% of the seeds are released after the emergence of the seeds to prevent burning of the young leaves. In the seedling stage, the water is added to the biogas slurry 2-3 times, and the bio-pesticide avermectin is used to prevent cockroaches. After the three-leaf period, the seedlings should be mainly used to reduce watering and increase the release of wind. The weeds should be removed in time to achieve the purpose of strong seedlings. When the seedling height is more than 20cm, 4-5 pieces of true leaves can be transplanted and planted.

4, transplanting

(1) Apply enough base fertilizer. In order to increase the nutrient area of ​​the leek, the leek seedlings were moved from the seedbed to a greenhouse that had not been planted for many years. The root system of amaranth is shallow, the root hair is small, and the ability to absorb fertilizer is weak, but its growth period is very long. Therefore, the application amount of base fertilizer is large. 5000kg of fermented biogas residue and 100kg of bio-organic fertilizer are applied in one mu of land. Spread the base fertilizer evenly into the ground, and then carefully turn it over again to reach the top of the virtual, and use the ten-toothed flat to prepare for transplanting. (2) Transplanting method. The nursery nursery is poured with water once every 34 days before transplanting. When the sensation is appropriate, the seedlings are shaken off, and the soil is graded according to the size of the seedlings. The top of the ground is 20cm long to the tip of the leaf, and the root must be 7-10cm. The seedlings that have been sorted are planted into the holes, and it is advisable to plant the leaves and sheaths in the soil. At the same time, the roots should be kept as far as possible to achieve planting, planting and planting. (3) transplanting. When transplanting, the row spacing is 20am, the plant spacing is 12-13cm, 6-7 trees per hole, and 25000 holes are planted in acre. After transplanting, the planting water is poured, and after 4-5 days, the seedling water is poured again. After the ground is dried, it is timely cultivated. Grass, water once 4-5d, until the seedlings. After slowing down the seedlings, weeding and weeding, while checking for lack of seedlings.

5, field management

In order to prevent pests such as onion, locust, and leaf miner from moving into the shed, 20m of insect nets are covered on the scaffold after transplanting, and yellow and blue traps are suspended in the shed, which can effectively inhibit the occurrence of pests. Spread, in addition, because of its small mesh, it can prevent the impact of heavy rain, hail and other on the leek, and has a certain moisturizing effect. Amaranth is not resistant to high temperatures. During the hot and rainy season in July-August, the photosynthesis of amaranth leaves is reduced, and the growth rate is obviously slowed down. During this period, the seedlings are mainly used, generally no fertilization, watering, and timely drainage and flood control after rain. To avoid plant lodging and rot, and to cultivate and weed in the middle of the season, the sunshade net should be covered on the scaffold during the high temperature period. After the autumn, the rainfall gradually decreases, the temperature drops significantly, and the average temperature is between 23-30 °C. It is the best time for the production of amaranth. It is necessary to strengthen the water and fertilizer management of the leek, generally pouring water for about 10 days, and pouring the water with the water. 2 large cans. At the same time, the growth and flowering of the flower buds consumes a lot of nutrients, and should be removed in time after the flower buds are extracted in the autumn, so that more nutrients are stored in the roots.

Amaranth may fall from spring to autumn. Most of the leek lodging is due to excessive growth, resulting in slender and slender stems or hypertrophy of the leaves, caused by heavy head and feet. The naturally lame amaranth is mostly draped over the leaves. If the treatment is not timely or improper, the lower leaves will be caused. Yellowing and rot, causing disease. For lodging of leeks, it is necessary to take corresponding measures according to the lodging period. If it occurs in the early stage, the upper leaves can be cut off by one-third to two-thirds to reduce the upper weight, increase the light between the plants, and promote the amaranth to restore its erect growth. If it occurs in the autumn, it can be ridged. The aged leaves and a part of the sheaths are removed by hand. The fallen amaranth can also be picked up to one side with a wooden stick, and the roots of the amaranth are dried on one side, so that one side of the plant is fully visible and the rows are sufficiently ventilated. After 5-6 days, turn the leeks to the other side, and let them dry and ventilate. If they are alternated, they can be remedied.

6, cutting

After the frost is cut, all dead leaves are removed in time. If there are residual stems, they should be scraped off and cleaned up. The height of cutting will directly affect the aging speed of the leek and the yield of the next one. Since the sheath of the leek has an active meristem, the leaves can be continuously elongated upwards, so the new leaves will grow soon after the cutting of the leek, and if the cutting is too low, the meristem of the base of the sheath may be damaged. The growth of leeks is slow, but the sorghum is too high and affects the yield during harvesting. Generally, 3-4 cm above the bulb is suitable for cutting.

7, loading pots

After cutting 3-4d, watering seedlings, transplanted to a 42cm long, 28cm wide, 15cm high tub, 12 pots, 10-12 per hole, 10cm thick nutrient soil in the pot, ie According to one-third of the biogas residue, two-thirds of the sand loam is made up. After planting, it is covered with fine sand 0.5cm, and then watered into the family management.

8, family management

The leeks are placed in a room at room temperature of about 20 °C for management. The temperature difference between day and night is 7-8 °C. The surface of the pot is kept moist. See dry and cast, 200 ml of biogas is poured with water every 7-10 days, and the soil should be loosened at the same time. The leeks can be harvested in about 25 days. 4-5 days after harvesting, the biogas slurry is poured with water, and the second meal can be harvested again in a month. After harvesting two crops, the harvest will not be harvested in the same year, continue to be managed as described above, until the slow growth period in summer, reduce the number of watering, and the pots can be covered with insect nets for pest control. After the cool weather, strengthen the management of water and fertilizer, promote the growth of leeks, cut the sorghum after the frost, enter the production stage of leeks, and harvest three sorghum in the second year.

The fine potted leeks are suitable for urban family planting, with simple technology, convenient management, multiple harvesting, clean and safe, and green environmental protection. This not only dispels people's concerns about the quality and safety of vegetables, but also lays a foundation for the development of organic vegetables.
