Planting techniques of black-skinned wax gourd

Black-skinned wax gourd is a common vegetable, which is actively planted by farmers in recent years. It has the advantages of high yield, high quality, resistance to storage and transportation, and has a good development prospect. So how to grow black wax gourd? Let's get to know it.

1. Sowing and raising seedlings

Select plots with convenient drainage and irrigation and fertile soil, apply 1000-1500 kg of rotten farm manure per mu, rake and rake flat, mix evenly with the soil, and then make beds. Before sowing, soak the seeds in 40 degrees warm water for 4 hours, then disinfect the seeds with low concentration of potassium permanganate solution for 3 minutes, fish out the seeds, wrap them with a clean white cloth, and of course accelerate germination at a suitable temperature. When the seeds begin to show white, they can be sown. Double-row sowing is used when sowing, requiring a plant spacing of 85-90 cm, sowing about 900 holes per mu, generally sowing 3 seeds per hole, and transplanting when the seedlings grow two leaves, leaving one seedling in each hole.

2. Fertilizer and water management

Black-skinned wax gourd needs a large amount of fertilizer, so it is necessary to apply sufficient base fertilizer and apply thin nitrogen fertilizer every 7-10Ian after transplanting, or 40-50 kg compound fertilizer per mu and 60-80 jin of raw bran. Fertilization in winter should be thin fertilizer frequently, light in front and heavy in back, reasonable collocation of nitrogen, phosphorus and potassium fertilizer, when melon vines on the shelf, water demand increases, should be watered frequently. Maintain soil application to meet the needs of melon growth, and pay attention to drainage in the rainy season to avoid stagnant water retting roots.

3. Pruning and pressing vines

Black wax gourd general main vine knot melon, in time to remove the side vine, in the fruit before the removal of all the side vine, on the shelf before the main vine in the range of plant distance hovering, every 3-4 nodes pressure vine, a total of 3-4 times, promote the formation of adventitious roots, when 16-18 nodes lead to the vine on the shelf. Three or four bamboo poles are used to build a drum rack, on which a bamboo pole is used as the dragon root. When the wax gourd grows to 3-4 jin, the handle is covered with a rope and tied to the dragon root of the drum frame. There are about 15 knots at the top after melon. At the same time, the melon should be retained reasonably according to the plant growth state, and the 3rd-4th female flower of the main vine is ideal, which can be pollinated artificially to improve the fruit setting rate.

4. Pest control

The main diseases of black melon are Fusarium wilt, blight and anthracnose, which can be controlled by chlorothalonil, methyl topiramate and other insecticides. the pest is mainly thrips, which is the most serious in 25-30 degrees and from July to September. The prevention and control is to spray Shachongshuang and Kangfuduo EC in time, and the chemicals should be used alternately to avoid drug resistance.
