Three cherry pepper cultivation management technology
One, nursery three cherry can be used Yangshuo nursery and small arch shelter seedlings, nursery seedlings mainly small arch. The specific approach is as follows. 1. The small arched sheds are generally 1.5--2 meters wide and 1 meter high, and they are covered with haystacks according to the climate at night. 2, the preparation of culture soil using fertile garden soil 7-8, decomposed manure 2--3 can be mixed, if the soil is heavy, but also mixed with sand. 3. Seeding time Spring sowing seedlings are usually arranged in mid-late and late February, but no later than March 5. Summer sowing is generally in mid-March, and it should not exceed March 25 at the latest. 4, sowing before sowing should be enough to fill the bottom of the water, until the bed can be no time to sow. The sowing method can be used for spreading or seeding. Generally, the seeds are spread evenly in the seedbed, and then immediately covered with fine soil that has been sieved. The thickness of the cover soil is preferably 1 cm. After sowing the soil, cover with a layer of plastic film (after the cotyledon is exposed, remove it in time), then cover the shed with a plastic film with good light and cover the grasshopper at night. Planting 667 square meters of land needs nursery 10--15 square meters. 5, seedling management do a good job in three links, that is, good insulation and anti-freezing at the beginning, to promote early emergence, a full seedling; a reasonable adjustment of temperature, humidity, prevent burning seedlings, flash seedlings and down seedlings. Seedlings, young seedlings and earth-covered seedlings were unearthed. When the cotyledons were fully developed, the first seedlings were planted, the seedling spacing was 1.5 cm, and the second 3--3 true leaves were unfolded for the second time. . After the exogenation management seedlings grow to 4--6 true leaves, the seedbed should be gradually released and the air release should be conducted at a high temperature in the sunny afternoon. When the surface soil of the water and fertilizer management nursery is dry, and the wilting occurs in the afternoon, the seedlings should be watered in time. Foliar spray was sprayed once every 7-10 days from the second true leaf. Second, the cultivation techniques 1, a reasonable fertilization, fine soil preparation 1 cornice selection. Three cherry peppers hi oysters, not continuous cropping, continuous crop yield reduction, low-lying water should not be planted; 2 Shizu base fertilizer, re-applied phosphorus and potassium fertilizer. Generally, 667 square meters of applied calcium phosphate 75 kg, potassium chloride 25 kg or potassium sulfate 20 kg. High-yield plots of 667 square meters of applied calcium phosphate 75--100 kg, potassium sulfate 20--30 kg, urea 25 kg; 3 fine soil preparation, ridging film. When plowing the soil, it is necessary to plunge deep into the soil to reach the finest soil. Plowing depth is appropriate at about 25 cm. Then ridging the film, when the film is covered, the film should be tightened tightly, and the surrounding area should be compacted and sealed with soil. 2, strong seedlings planted early, rational close planting 1 three cherry pepper transplanting time. Generally after the frost, the temperature steadily rose to 15°C and transplanted as soon as possible. The spring sowing requirement is completed around May 1st. Summer sowing requires timely transplanting after wheat is harvested. It should be completed by June 20 at the latest, the sooner the better, 2 transplanting methods. The day before transplanting, the seedbed should be irrigated so as to bring more soil, less root damage and reduce damage to seedlings. Due to the impatience of the three cherry peppers, the seedlings should be planted on the pods during transplanting, and each line should be planted in two rows. It is advisable to plant the seedlings in such a way that the roots can be wetted by watering. According to the spacing requirements of the plants, firstly a single planting hole was dug on the mulch, and then the larvae were planted into the planting holes. The soil around the seedlings was compacted with soil. Watering immediately after planting; 3 rational close planting. Sanchajiao has a small plant type and compact plants, which should be planted in the field. Line spacing 40--50 cm, 20--25 cm from the hole, 667 square meters planted 6500--7000 points. 3, field management 1 fertilizer and water management. A one-time fertilization method was used, and no fertilizer was applied during the growth period. However, the poor field to protect the fat should be in the fruit after the fruit set up after the three cherry peppers. During the growth period, the soil must keep dry and wet. In case of drought, timely watering, and preferably in the evening on a sunny day. Avoid watering under the hot sun; 2 weeding and weeding. After the three cherry blossoms are transplanted, the cultivars must be cultivated in time and cultivated for 2 to 3 times before flowering. In case of rain, the cultivator will be ploughed in time after rain Accelerate evaporation of soil moisture and increase ground temperature. Weeding can be done in combination with cultivator, but do not damage the mulch; 3 topping. The seedlings are topped in a timely fashion 5-7 days after transplanting, thus limiting the growth of the main stem and triggering the emergence of lateral branches to achieve high yields. Summer sowing generally does not need to top. 4, pest control hazards The main pests of the three cherry peppers are aphids, cotton bollworm, cabbage caterpillars, etc., can be used to control aphid net 1000 times liquid or green 2000 times liquid foliar spray. The main diseases that endanger the three cherry peppers are: wilt disease, epidemic disease, charcoal disease and soft rot disease, etc. The above diseases are easily contaminated during high temperature and rainy season. Onset plots can be treated with mancozeb, chlorothalonil, chlorpyrifos, and soft rot can be controlled by agricultural streptomycin. 5, timely harvest, do a good job classification drying three cherry due to clustering, mature, generally in the whole fruit planted when the frost or the fruit is fully mature, one-time harvest, drying classification.
