How many kilograms of watermelon are normally produced per mu? How to increase the yield?

Watermelon yield per mu

The yield of watermelon per mu is generally between 5,000 and 10,000 jin . First of all, we must choose excellent varieties. The yield of watermelon is closely related to the cultivation variety technology and environment. For small individual watermelons, a yield of 4,000 to 5,000 jin per mu is considered a very good result.

Watermelon planting prospects

1. Planting costs and profits

  The cost of growing watermelon is not high, mainly including watermelon seeds, land rent, fertilizer, pesticide, agricultural film, water and electricity, as well as labor and other expenses required for growing.

The cost of seeds is generally around 300 yuan, the cost of fertilizers, agricultural films, and pesticides is generally around 1,000 yuan, and the other costs are about 2,500 yuan, which means that the cost of planting one acre of watermelon is about 3,800 to 4,000 yuan. The yield of watermelon per acre is about 3,100 kilograms, and the current purchase price is generally 3 yuan per kilogram. The income of one acre of watermelon is 9,000 yuan. After deducting the cost, the net profit is about 5,000 yuan.

2. Planting prospects

  The market price of watermelon is greatly affected by the season. In the past, when planting technology was not well developed, watermelon could only be harvested in summer, and the yield was not high. Therefore, the market price of watermelon would rise. Now that planting technology has improved, it can be planted in any season, and the price of watermelon in the market is also different.

The price of watermelons is the lowest when they are on the market in large quantities in summer. We must grasp the season and choose good watermelon varieties to increase profits.

How to grow watermelon to get high yield

1. Open field sowing: When the buds emerge, they can be selected for sowing. Remember to keep the bud tip facing downward. Water the roots immediately after sowing. If it is a sunny day, water it once every two to three days. The seedlings should be transplanted when they have two to three tender leaves.

2. Apply nitrogen fertilizer appropriately and apply phosphorus and potassium fertilizer heavily: If only nitrogen fertilizer is applied or too much nitrogen fertilizer is applied, the watermelon will be large but the sweetness will be poor and the benefit will be poor. Apply nitrogen and phosphorus and potassium in appropriate amounts and the melons will be larger. Nitrogen grows the melon, phosphorus promotes root growth and increases the sweetness of the watermelon, and potassium strengthens the vines. It can also enhance the watermelon's resistance to drought and disease, and can also enhance its sweetness and storability.

3. Press and organize the vines: When the vines are more than 40 cm long, prune and press the vines on a sunny day to straighten and evenly arrange the vines. It is fine as long as the growth point is in the right position. After the young melons are firmly seated, remove the tops in time while retaining most of the leaves.

4. Artificial pollination: Artificial assisted pollination can increase the fruit setting rate and increase production. From 9 to 11 a.m. every day, pick the open male flowers, tear off the petals, expose the stamens, and gently smear them on the female style so that the pollen sticks to the stigma. Artificial pollination should be done gently and do not touch the ovary with your hands.
