Can you make money by planting black melon in 2019? What planting techniques are there?

The black-skinned wax gourd is the "black pearl" in the wax gourd, the tender melon is green, the mature melon is black, and it is bomb-shaped. So, can you make money growing black-skinned wax gourd in 2019? What is the yield of black-skinned wax gourd per mu? What are the planting techniques?

First, can you make money growing black wax gourd in 2019?

The economic benefit of black-skinned wax gourd is better. After deducting fertilizer, pesticide, seed, plastic film, bamboo frame, labor, land rent and other miscellaneous fees, the net income per 667m2 is generally several thousand yuan, but it takes at least 4 months from sowing to harvest, and the management of each stage must be in place in order to achieve the expected harvest.

It can be harvested when the peel turns dark green and the leaves turn yellow. Generally, the first melon production is in mid-May and the second melon harvest is on the market at the end of November.

The black-skinned wax gourd planted with two-cropping technology in one year has a yield of 6000-9000 kg per mu. When the market is good, the annual output value per mu is more than 10, 000 yuan. Black-skinned wax gourd not only has high planting efficiency, but also has broad planting prospects.

Second, what is the yield of black wax gourd per mu?

The yield of black-skinned wax gourd per mu is generally more than 5000 kg, and the high yield can reach more than 10000 kg. The best growing place for black-skinned wax gourd is Hainan and Guangxi.

Third, what are the planting techniques of black wax gourd?

(1) sowing date. Sowing seeds during the period from "Lesser Cold" to "Greater Cold" (that is, January 5-20) shall not exceed the Beginning of Spring at the latest.

(2) selecting land and preparing land. Select fields with convenient drainage and irrigation and fertile soil, rake them into pieces and rake flat, and ridge every 1.9 meters.

(3) apply sufficient base fertilizer. 1000-1500 kg of rotten pig manure is applied per mu, and strip application is better. The method is to make trenches on both sides of the ridges, cover the soil after applying pig manure into the ditches, and sow seeds on them.

(4) heat preservation and budding. Soak the black-skinned wax gourd seeds in 40 ℃ of warm water for 4 hours, then disinfect them with potassium permanganate solution (light red as the standard) for 3 minutes, pick up the seeds, wrap them in a clean white cloth, and put them into a washed steel pot to keep warm and accelerate germination. The steel pot holds 2.5 kilograms of water, the wooden frame is placed in the pot, and the seeds are placed on the wooden rack. Keep the temperature in the pot about 35 ℃, no more than 40 ℃ or less than 30 ℃. After 36-48 hours of heat preservation, the seeds can be sown after the seeds begin to germinate.

(5) sowing seeds. Using double-row sowing, the plant spacing is 85-90 cm, sowing about 900 nests per mu, sowing 3 seeds per litter, and then the melon seedlings grow to the two-leaf stage, leaving 2 seedlings per litter and 1 seedling per litter in the five-leaf stage. Pay attention to the seeds can not be sowed directly on pig manure, it is appropriate to leave pig manure 10 cm, lest pig manure fermentation burn out the seeds and affect the germination rate.

(6) Water management. Wax gourd has developed root system, large leaf area and more water evaporation, so the requirement of water for wax gourd is higher than that of other melons. Sunny and warm weather, the soil is drenched sooner or later when the soil is dry. After the melon vine is on the shelf, the water demand increases gradually, and the flowering and fruiting period reaches its peak. During this period, water should be drenched frequently to keep the soil moist, and water should be drenched at least once a day in sunny days (do not drench water in the afternoon). Waterlogging should be excluded during the rainy period so as not to cause diseases. In the first 10-15 days, the water consumption was reduced and the waterlogged ditch was drained to improve the storage and transportation performance of wax gourd.

(7) Disease and pest control

The main pest of wax gourd is thrips, which can be sprayed with 5000 times of 20% acetamiprid wettable powder, 2000 times of 10% Jin Yongan, 1500 times of 90% Wanling wettable powder, or 3000 times of imidacloprid wettable powder. Spray leaf bottom, vine and melon every 5 to 7 days.

The main disease is blight, prevention and control methods: first, adhere to crop rotation; second, strengthen field management; third, chemical control measures: chemical control starts at 10 leaves of wax gourd, spraying once every 7 to 10 days, 58% Redomir wettable powder 600 times liquid, or 77% can kill 600 times liquid, or 0.6 ~ 0.8 °b é Bordeaux solution (that is, ready-to-use), the above prescription alternately sprays leaf bottom, leaf surface, vine, melon, ground.
