Post-autumn cucumber cultivation, which involves planting from mid-july to late august, planting from early august to late august and supply-market cultivation from mid-september to late november, is generally expensive and cost-effective. Because of the low temperatures in the late season and the limited capacity of the sheds to raise the temperature, it is important to be careful that the planting season is not too late for the desired yield
1. Choice of varieties
The selection of varieties for the pre-temperature high-temperature endurance, strong female division, high strength, disease resistance, high yield and good quality。
2. Cultivation of seedlings
1 the planting of cucumbers after the fall of the sun-shield should take place in the shed, in the mid shed or in the small arch fence, with ventilation around them. In the sheds, seedlings are produced, the front foot is removed, the rear vents are ventilated and the cavity is formed. It can also be made directly on the ground as a blubber of 1. O-1. 2 m wide and approximately 6 m long. High-quality organic fatty of 50 kg sifted per thorium is used as seed-based fattening, 10 millimeters of depth, soil is plattered, and can be moved or broadcast live on the dredges, with an arch shelf of 0. 8 to 1. 0 metres on the thorium, covering the old membranes, providing rain cover and night dewproof water。
Although cucumbers are available live after the autumn transplant, it is preferable to have a seedling in the form of a seedling transplant, which generally does not use incubation. The cucumber is sowed with sand beds, 8 to 10 centimetres thick of sifted river sands, dredges and water, so that the cucumber seeds are spread evenly on the sand. Two centimetres of sand are covered, water is poured, the sand is always wet, and two leaves in three to four days can be transplanted. The seedlings start at one end, open a ditch at a distance of 10 centimetres at which sufficient water is poured and the seedlings are transported at a distance of 10 centimetres. More use is currently being made of nutrients or cave breeding。
The management of seedlings during the sapling season, which is hot and wet and prone to frost and disease, should begin to be intensified after cucumber seeding. High temperatures and high evaporation during the period of seedlings are to be kept dry and wet, and water is to be poured in the morning and evenings until the water has just reached the surface。
3. Fertilizing the whole area
Following the harvest, timely and complete fertilization is generally done using 5,000 kg of high-quality cormorants per acre, 50 kg of phosphorus powder and 20 kg of potassium powder (or 50 kg of grass-wood ashes) as base fertilizer. It is then watered to the ground when the soil is dry and wet, and then rises to the ground, to the bottom of which is 80 centimetres wide, opening 20 centimetres in the middle and forming two 30 centimetres wide and 10 centimetres high. There are 40 centimetres of ditches between the two giants, each of which grows a row. It can also be planted in a single line, with 40 cm or so, with small lines。
4. Demolitions or live broadcasts
Before planting, water is pumped with seedlings, which are then scavengered and selected to grow a sapling of the same size, 20-25 cm, with 4,500 to 5,000 plants per acre. The seedlings are planted in ditches, which are solid, with large amounts of water in the ditches, and then, when the soil is dry and wet, they are then sealed. It is not appropriate to be too deep for the depth to be set at the level of the sap and the slab。
Live coverage in front of the shacks can also be used to save seedlings and not to remove their roots and grow. At a distance of 70 cm from the main line, 50 cm from the small line, high gills or pick-ups, the first two to three days of seeding, the depth of which is 3 cm from the open ditch, the seeds of the sprouts are sowed at a distance of 25 cm, with 2 to 3 grains per den and 1. 5 cm from the back of the earth. If there is a lack of affection, the seedlings should be pumped with water. In the event of a rainy day, weeds should be built to prevent soil sheeting, which will normally produce seedlings after three days, and seedlings after two real leaves. When seedlings, disease seedlings, malformation seedlings and weak seedlings are found, they should be replanted in secret。
5. Field management
1 temperature humidity regulates the high temperature of the prior period of the melon, and the thin film around the shed shall be rolled up only to the top of the shed and given a major ventilation. (c) the timely planting of beaks and the reduction of soil moisture。
2 fertilizer management should prevent seedlings from growing, less or less water, less nitrogen fertilization, more phosphorus, potassium fertilizer, or 2-3 organic camps. The plug can be preceded by a fat hunt with 300 kg of manure or decomposed manure per acre. Following fertilization, water plugs or chickens. Cucumbers. 2-3 times, 500-750 kg of rotting manure per acre and 2-3 times of organic nutrient fattening with water. When the temperature is high, the water can be poured every five to six days at later temperatures, and in late october, the water will be poured. In november, 0. 1 per cent of boron can be sprayed to prevent fertilized melons。
From planting to planting melons, pine soil is usually cultivated three times, so that the soil is deflated, the number of times water is reduced, the number of planters is controlled, the root melons sits down, the cultivation is stopped. The melon period and later shall be utilised as appropriate. The cucumber is grown late in the autumn, with high seating levels, and should be mounted and tied to chickens in a timely manner. This can be done using plastic ropes for chickens, and when the roof is planted, the heart is removed and the side branch grows. Usually two i-hearts on the chicken, which can be used to increase lateral production。
