Black Beauty watermelon frame cultivation techniques
Black beauty watermelon is a long oval, dark red meat, tender and juicy, high sugar, fruit weight is only 2-3kg, petite and exquisite, is a typical small watermelon, is very popular, very popular in the market, the market price is strong, than Ordinary watermelons sell for 3 to 4 times more. However, due to the small size of the melon, if the cultivation is still carried out according to conventional methods, the yield of 667 square meters is only about 2000 kg, and the yield is low. In 2000, the city tried a blackberry watermelon high-density cultivation method, which not only reduced the watermelon disease, but also obtained a bumper harvest. The average output of 667 square meters can reach about 4000kg. The cultivation points are:
First, the election
The watermelon is deep-rooted and its roots are underdeveloped. As a dense planting black beauty watermelon land, it is best to use good drainage, deep fertile soil layer, loose, adequate light, and in recent years did not plant a field of melon crops (except for the use of grafted seedlings). The pH value of the soil is preferably 6 to 7. If the acidity is too strong, the lime can be properly neutralized.
Second, do earthworms in the field and apply enough basic fertilizer.
After deep-sloughing the soil, it can be used to make rakes, with a width of 2.6m (including a ditch of 30cm) and a height of 25cm. Each row was planted with 2 rows of planting furrows with a spacing of 1.3m. After the completion of the planting, apply 3,000kg of quality organic fertilizer, 30kg of superphosphate, potassium sulfate (preferably without potassium chloride) 15kg, compound fertilizer 30kg per 667m2 planting trench, and mix the manure and soil thoroughly. In this way, sufficient supply of fertilizers can be ensured and the watermelon vines can grow robustly.
Third, the density of colonization
In general, spring cultivation in this region was planted in March, and autumn cultivation was planted in June to July. The planting method was adopted with a row spacing of 1.3m and plant spacing of 30cm, and 1710 plants were planted at 667 square meters.
Fourth, ensure Qimiao
After planting, it is necessary to strengthen inspections, diligent in management, check seedlings to make up seedlings, and ensure that Miao Qi, Miao uniform and Miao Zhuang.
V. Early application of fertilizer
About 4 days after planting, thin water and manure can be applied. 0.1% to 0.3% urea water or sulfur-containing compound fertilizer can be used to rinse the roots of the seedlings, once every 5 days, and apply 3 times in order to promote the growth of stems and leaves and cultivate strong seedlings. When the seedlings grow to 50cm long, 667 square meters and then 50kg of compound fertilizer, it is best to add decomposed peanut bran 50kg or other organic fertilizer 1000kg together. Cover the straw with fertilizer to keep the soil moist. Flowering generally do not apply fertilizer. After the expansion of the young melon, special attention should be paid to the management of fertilizer and water. When the melon grows to the size of the fist and the fruit is half large, 0.3% urea water or sulfur-containing compound fertilizer can be used for water application. The fertilization interval should be shorter than the conventional one and applied once every 5 days. And the number of fertilization is also more than conventional.
Six, pruning vines on the shelves
1. Pruning: pruning method should be adapted to local conditions, the general management level, fertilizer and water conditions are good, you can use two vines or three vines, melon, fertilizer and water conditions are generally recommended to use a single vine nectar. Use single vine melon, leaving only the main vine, all vines should be removed, sitting after the melon (usually in the thirteenth seat sitting melon, the same below), sitting guaranes before the position can stay 3-4 side vines Nutrient vines. Using double vine berry, pruning method is: when the plant leaves 3-4 true leaves, then leave 2 vines with strong and consistent growth as the guava vine (ie, leave 2 main vines). The side vines growing from the main vines should all be removed. After sitting on the melons, 2 to 3 side vines can be left as nutrition vines before sitting in the melon section. The use of three vines (less commonly used), the pruning method and the double vine squash pruning method is the same, but it is only to pick up the heart after leaving three robust vines for Guagua.
2. Stretching: In each of the two planting rows, use a thin bamboo rod to hold the "well" frame, and two bamboo piles at the ends of each row to hit two large bamboo piles or stakes of about 1.2m in height, and then use half of the mud bamboo pieces. It is fixed between the big bamboo piles at both ends to reinforce each row of "wells". At the same time, the two rows of "wells" in the temple can be fixed with bamboo poles at regular intervals to prevent winds from falling down.
3. Leading vines: To extend right at a right angle to the planting line, the main vines in the larvae should be kept at a certain distance and be led to the other side's "well" frame to climb to make full use of the space in the sampan area. Ensure a reasonable lighting area.
4. Solid vine: After a certain length of vine is spread, it must be fixed so that it will not be flipped by the wind.
Seven, fruit set
The first female flower should be removed. The best position for melons is the second female flower, usually around the 13th, which is too high and bad. Every vine spreads one melon. Good soil and fertilizer conditions can leave 2 melons. Malformed melon, melon and other bad melons should be removed as soon as possible. 3 days before the pollination, borax 108 (or boric acid 5g) and potassium dihydrogen phosphate 50g can be sprayed on the water, which is good for melons.
Eight, hanging melon
When the melon grows to be slightly larger than the size of the table tennis ball, the melon must be hoisted so as not to drop it. A plastic mesh bag can be used to hang the melon, or a string can be used to lift from the base of the squash handle, and the straw ring can also be used for hanging.
Nine, artificial pollination
In order to increase the fruit setting rate, artificial pollination must be carried out, that is, collecting male anthers that were opened in the morning and lightly applied to the stigma of the female styling that has just been opened. However, it should be noted that you can't apply too much pollen on the stigma, just stick it, otherwise there will be more melon seeds.
X. Pest Control
Mainly viral diseases, wilt disease, anthrax, epidemics, downy mildew, aphids, and boron deficiency disorders. Diseases can be controlled by chlorothalonil, radomil, carbendazim, acetaminophen, virus A and other pesticides, and insect pests can be sprayed with pesticides such as dichlorvos and insect pests. From the seedling stage, we must observe it regularly, discover it in time, and prevent it in time.
XI. Harvesting
Black beauty from sowing to maturity, spring and autumn is generally about 90 to 100 days, hot summer only about 70 days. Flowering results to maturity Generally, it takes 30 days in spring and 28-30 days in summer. Everywhere is different.
