The farmer's answer:
It is a new system of research that is cultivated and requires a very high level of demand for the growth environment and soil, as well as for sunlight, but even though it takes about 60 days to grow, it takes about 60 days to bloom and harvest, the farmers of weinzhou and hainan are willing to grow because of short cycles, tastes and benefits。
Pick a shed
The choice was to build shelters with high terrain, good drainage and deep earth. Low-lying, poorly drained plots are not suitable for construction. It is requested that no melon crops be grown in three years, and jiangxi has chosen to plant “pricot” with rice fields。
The sheds that cultivate watermelon generally use simple bamboo-formulated sheds that are better north-south, 4. 5-5 metres wide, 25-30 metres long and 1. 8-1. 9 metres high. The two sheds in the same row are 80-100 cm and the distance between the two rows is 2. 5-3 m. The mackerel used in general is approximately 7 metres long and 5 centimetres wide。
During the construction of the sheds, a small hole of about 30 centimetres per 50 to 60 centimetres was struck by steel plating on the plots of the sheds, drawing the edges of the sheds on the basis of the extent of their length and on the sides of the two long edges. The mackerel is then inserted into a small, pre-established hole, the base (bold) and the top (substantial) of the bamboo are rotated, and the arch is tied to the top of the roof with a pole, which binds the whole of the hut together, and the entire archepost of the top is on the same level. It is then reinforced by a tilt pole on both sides of the shed, which is then covered with a sheet of film, which crushes the mud on the foot of the shed, tightens the sheet of film and keeps the shed doors on both sides。
We'll open the ditch
1. Gaps: the drains are constructed around the sheds, which require a depth of 50 centimetres, a width of 30-50 centimetres, and a width of 25 centimetres and a depth of 25-30 centimetres between the shed and the shed. There is a demand for heavy rain weather, and water in the ditches can be drained out of the ditches, and no water accumulation signs can emerge, which could otherwise lead to the decay of the watermelon。
2. Land improvement: land is grown in watermelon areas, which, during the winter season, should be deep-seated and thawed. In cases of excessive soil acidity, it is possible to use lime and acidity, usually 100-150 kg of lime per acre and then arable land。
3- pyramids: the water-guana canyon is grown at a high height, usually at a length of 4. 5-5 metres in two gills, approximately 2. 3 metres wide, with the back of the turtles, each of which opens only one gutter in the centre for 40 centimetres and 20 centimetres deep for two sides。
4 bottom fertilizers: 2,000 kg of fertilized organic fertilizers per acre, 25 kg of phosphorus fertiliser, 15 kg of potassium sulphate compound fertilizer, 50 kg of vegetable loaf, fertilizers to be applied to abronated soils and 1. 5 kg of molybdenum. The bottom manure should be applied in the middle of the gutter and then to the ground。
5 drill hoses and membranes: the first half of the month is flatted, drip irrigation is prepared, the membranes and the membranes are warmed up, requiring temperatures above 15 degrees celsius。
Feeding techniques
Cultivation is generally carried out in sheds + sheds + membranes, with the conditions for planting seedlings using thermal heating line in mid-december and shifting cultivation in mid-february. It would be useful for those without heating equipment to sow seedlings in mid-february and to move in late march。
1. Selection of seedbeds: the seedlings should be carried out in the sheds, and it would be useful to choose fields closer to the fields to be grown, dry, windy, well-lighted and easily drained。
2 nutritional home-grown: the nutrient soil requires laxation, fertility and water conservation, which requires more than one month in advance. Paddy fields that have not grown in melons for more than three years are added to the corroded farmers ' fats, compound fats, phosphate fats and grass-grass ash, etc., which are modulated and covered with membranes. The paddy field is corroded with the fertilized farmer ash = 5:3:2, with 5 kg of phosphorus and 2 kg of corroded fertilizer in a cubic nutrient soil. During the mixing process, 50% more than 600 times more fungus or 1% more of the ffl can be sterilized and remoulded and dried。
3. Preparation of seedbeds: around 400 per acre of watermelon. Set up a nursery and make an electric hotbed. The bed is made up of 1. 3 metres wide, the bed is dug to a depth of 5 centimetres deep, depending on the need, and an old film is laid below the temperature, filled with two centimetres thick of grains, a non-disease-skinned earth is covered, and a hotline is made to warm itself, 1,000 watts per 10 square metres of seedbed, thinner in the centre, and somewhat dense on both sides. The power supply, switch, selects 10 cm x 10 cm specification plastic nutrients, which are then installed on the seedbed's hotline, covering the membrane to keep the temperature warm。
4. Drum seeding: one day before seeding, 15-30 minutes bathing in 55°c hot water and mixing while immersing. Or be treated with 1% formaldehyde solution for 10 minutes, washed with water, then immersed for 6-8 hours. The seed surface glucose is then washed clean, the seed is packed with wet cloths, and sprung at a temperature of 28°c-32°c (with the use of human temperature or electro-heat blanket sprouts), usually in white seeding after 24-30 hours. The first two days before the seeding, the nutrients were filled with subterranean water and electro-preheated seedbeds were installed to contain soil temperatures above 25°c. The planting is suitable for the morning of the sun, with each seed spread flat, followed by the covering of 0. 5 centimetres of the earth, properly watered with a membranes and a small arch shed to keep warm。
V. Shrimp management
1 temperature: pre-suppression follows a high temperature in small arches of 28-30°c during the day and 18-25°c at night. When 30 per cent of the new seedlings are soiled, the membranes covered by the nutrients and small arches are ventilated. Post-plant shed temperatures are around 25°c during the day and 15°c-18°c at night. If the temperature is insufficient during the nursery period, electro-heating wires will be applied。
2 humidity: the soil moisture management of nutrients in the nursery is based on the principle of “dryability and unwetting” and water is not watered as much as possible after seeding and until the leaf is ready, depending on the dry and wet state of the nutrients, the soil is not white and the soil is not watered with water, which should be watered at noon. The sheds should be ventilated as much as possible in conditions of guaranteed temperature to reduce humidity and avoid disease. In the event of the onset of rain and the atrophy of new leaves, the shades of the sunnet should be properly covered and the buds restored to normality. Water was stopped 5-7 days before the planting. In the case of seedlings, which generally do not need to be followed by fat, e. G., small seedlings grow thinly and can use 0. 3 per cent urea and potassium phosphate for external fat。
3 lights: during the sapling season, the small seedlings will be luminous and the small arches will be exposed during the day. Artificial light should be used on intermittent rainy days, with 300 watts of incandescent light for every 10 m2。
4 pest control and treatment: early spring seedlings are susceptible to a variety of diseases such as fallout, due to low temperature and high humidity of their beds, and can be treated and treated with drugs such as prick, dalian and mercantile manganese zinc, in addition to minimizing humidity in the shed. In the case of intermittent low-temperature and low-light rainy days, the pharmacants may be used to dry the soil and sow it in the nursery. Pre-plant spraying of more than 50 per cent of the fungus 600 times the liquid charge。
