Black beauty watermelon is one of the sweeter watermelons. It is widely planted because of its bright red meat, good productivity and wide adaptability. Where does it come from? When will it be ready? How do you plant it? Which areas are suitable for planting?

Introduction of origin:

Black beauty watermelons are produced in many places in China, the most famous of which are Nanning, Hainan, Yinchuan, Ningxia and Weinan, Shaanxi.

Planting time:

Spring cropping from February to April, autumn cropping from June to the end of August is the most suitable, spring cropping in the early growth stage in the low temperature period, late growth in the high temperature period, autumn cropping is on the contrary. The days required for spring cropping are longer than those for autumn cropping, and the fruit shape is larger and the flesh color is darker. Sowing in the low temperature period, in order to prevent the cold, it is appropriate to use the tunnel shed to keep warm and raise seedlings. When there are two true leaves, they can be planted in the field.

Planting techniques:

First, sowing and raising seedlings

1. Preparation of nutritious soil: nutritious cup is used to raise seedlings, which requires 150 kilograms of nutritious soil per mu. The nutritive soil is made of 70% pond mud, 20% rotten organic fertilizer and 10% pure red mud sieve. Each bag weighs about 0 or 5 kilograms, and put 6-7 grains of compound fertilizer in the middle of the nutrition bag. The raw materials for the preparation of nutritious soil should not be used in the soil that has been planted before.

2. Accelerate germination and sow seeds: soak the seeds with 50% carbendazim 500 times solution for 30 minutes, then soak them with clean water for 4 hours, pick up and accelerate germination until 70% of the seeds are white and sow. When sowing, the nutritious soil is first drenched with 500 times the liquid of carbendazim, the seeds are laid flat, the depth is about 1 cm, and the buds are down. After sowing, the seedlings are covered with nylon film to keep the nutritious soil moist. Generally, it can be unearthed 5-7 days after sowing. After unearthed, the cotyledons should be shelled manually to promote cotyledons to unfold as soon as possible.

3. Cultivate strong seedlings: spray the seedlings once every 7-10 days with 50% dimethoate 800 times solution and 50% carbendazim 500 times solution. When the first true leaf grows, it begins to be irrigated with mature human feces and urine 10 times as much as water, every other day. In the early morning of a sunny day, you can lift the film to refine the seedlings and re-cover it in the evening. The value can be set when the seedling grows to 2 or 3 true leaves.

II. Land preparation and planting

1. Land selection and preparation: select sandy land with sufficient sunshine, convenient drainage and irrigation, deep and loose soil layer to build a border for planting, the width of the border is 3 meters, the width of the ditch is 0 or 5 meters, and the border surface is slightly curved. Soil preparation can evenly spread 50 kg of quicklime per mu, which can not only disinfect but also neutralize the acidity of the soil. Per mu, 1000-1500 kg of rotten pig and cow manure, 20-25 kg of superphosphate, 30 kg of compound fertilizer and 10 kg of potassium sulfate were applied as base fertilizer and mixed with the soil.

2. Planting: when the seedlings grow to 2 or 3 true leaves, the distance between plants is 0 or 5 meters, and 330 plants are planted per mu. After transplantation, 50% carbendazim 500 times solution was used as root water. Then spread a film on the border surface on both sides of the seedling, and make the film close to the border surface, compacted without overturning.

A suitable place to grow:

Black beauty watermelon has wide adaptability, can be cultivated in four seasons in South China, and can give full play to its variety advantages in high temperature period, and its fruit is also larger. This variety is suitable for cultivation in all kinds of cultivated soil.
