What planting techniques do you need to master if the towel gourd is to be high-yielding?

Towel gourd is called watermelon or victorious gourd in Cantonese. Pearl River Delta towel gourd refers to star anise gourd, which is a kind of cucurbitaceae plant native to India, also known as vegetable gourd, which is widely cultivated in East Asia. Towel gourd has strong adaptability, high temperature resistance, low temperature resistance, drought resistance, and strong resistance to diseases and insect pests. The ability of absorbing water and fertilizer is strong, and all types of soil can be planted. What planting techniques do you need to master if towel gourd is to be high-yielding? When do you usually plant it?

First, when is the towel gourd usually planted?

1. Cultivation in winter and spring: sowing from November to January-February of the following year, harvest and listing from December to April of the following year.

2. Summer and autumn cultivation: sowing from June to September, harvest from July to November.

Second, how to produce high yield towel gourd? What planting techniques should be mastered?

1. Light and temperature management: towel gourd in the whole growth period requires a higher temperature, the optimum temperature for growth is 20-24 ℃, the optimum temperature for fruit development is 24-28 ℃; the growth is slow about 15 ℃, and the growth is inhibited below 10 ℃. During the day, the temperature in the greenhouse is kept at 25-30 ℃. When the temperature is too high, it is necessary to let out the air and open the tuyere gradually to avoid rapid cooling.

two。 Water management: on the basis of watering enough planting water, generally do not water before hanging seedlings, which is beneficial to towel gourd roots, such as drought, suitable watering for soil moisture once, after hanging seedlings, combined with fertilization and watering once, after setting gourd, the demand for water increases, after each flower dipping, combined with fertilization and watering once, towel gourd is a wet crop, requiring the ridge surface to see wet but not dry.

3. Strapping vines: 15 days after transplanting, when the vine grows to about 40 centimeters, it is necessary to lift the seedlings. The nylon rope with suitable thickness is directly tied to the iron wire of the greenhouse support to form a single-row vertical frame, the top is not crossed, the vine is drawn vertically according to the original planting row spacing and density, and the rope is tied under the top three leaves of the melon vine, which can not break the main tendry. and the main vine elbow does not grow.

4. Pruning, heart-picking and plastic surgery: immediately after hanging the seedlings, start pruning for the first time and remove all side branches, flowers and tendrils. Then tidy up every 5 days, leaving only the main vine to grow rapidly. About 36 days after transplanting, the towel gourd began to leave flowers when it reached 16 true leaves. After leaving two forks with melon buds in the uppermost part, the top growing point and all other forks and flowers were removed and lifted with rope after finishing. When there are three true leaves, melon buds and seed fork branches in the spare fork branch, leave a good spare fork branch and remove the apical growth point and another fork branch. By sorting out melons again and again in this way, you can keep good melons with uniform strips and similar size. The peak period of melon removal of diseased leaves and too many flowers, tendrils, removal of diseased melons, worm-eaten melons, deformed melons. Towel gourd will enter the rapid growth stage after touching flowers, in order to prevent the lower end of the melon falling on the leaf vine to cause curved melon, for the long straight melon, you can hang a small stone at the bottom of the melon, you can straighten the melon.

5. Fertilization management: the basic nutrient supply of towel gourd in the pre-growth stage can be provided to a great extent after the application of base fertilizer, but quick-acting nutrients need to be supplemented during the melon-setting period to facilitate the expansion of towel gourd. The specific methods are as follows: first, organic flushing fertilizer An is applied to the root after hanging seedlings to facilitate the rapid growth of towel gourd, diluted with 25 liters of root-promoting synergist per mu, and irrigated into Second, organic flushing fertilization B should be applied once after each flower dipping, once a harvest, once a month; third, in order to supplement trace elements and adjust the balanced absorption of various nutrients, the nutrient balance agent was sprayed for the first time after hanging the seedlings, and then every 15 days, the nutrient balance agent was divided into An and B, and the nutrient balance agent should be sprayed in the early morning with the best absorption effect.

6. Flower and fruit protection: the use of special flower potion can reduce falling flowers and significantly increase the rate of melon setting. Start operation after 3: 00 p. M., choose a better flower girl who is about to bloom that night and dip it directly in the liquid medicine to avoid touching the melon stalk and remove another spare flower girl. Such a mature loofah will grow straight and bring fresh flowers at the top, resulting in an increase in yield and high commodity value.
