Management of flowering and fruiting period of watermelon

Watermelon planting management is always to be maintained, but the focus of management is also the key period of growth and development, that is, the flowering and fruiting period. Flowering needs to sparse flowers and protect flowers, select flowers and keep flowers, and as a result, you need to select fruits to ensure fruit setting rate, and then you need to take care of fertilizer and water management. In addition, I will try my best to ensure a good growth environment, so today I will talk to you about the management of the flowering and fruiting period of watermelons.

First, thinning flowers and fruits

After flowering, the main fruiting lateral branches on the main vine should begin to select flowers and sparse flowers, generally robust lateral branches leave more than 6 to 8 flowers, and the rest are thinned. Keep flowers to keep well-developed, disease-free flowers, and then leave 5 to 6 high-quality flowers on weaker side branches, then keep 3 flowers, and the rest of the side branches can be removed. Generally retain 7 to 8 lateral branches, lateral branches can also leave 5 to 6 branches on a branch, leaving about 5 flowers on the branch. Others are omitted. The fruit was observed half a month after fruit setting, leaving more fruit on the strong and suitable branches, about three to four, and two weak ones, no matter how weak they were, they did not leave fruit for the development of nutritious branches.

2. Fertilizer control and water control

Watermelon flowering period is not watered or less watering, watering is easy to physiologically fall flowers, but drought is also falling flowers, as long as it is not dry, less water is enough to blossom. Flower-promoting fertilizer can be used half a month before flowering. In order to ensure the use of fertilizer for the whole flowering period, farm manure should be applied for about 400 jin per mu, and then 0.2% boric acid can be sprayed to protect flowers after flowering. After the result is a quick-acting compound fertilizer, usually a quantity of 90 jin, can be used in the fruiting period, three to four times, in batches to provide nutrition for each batch of fruit to protect the fruit. Irrigation in the result period is carried out in the evening, about once every half a month. Water thoroughly each time to ensure a dry and wet state.

Third, light temperature

For watermelons to store sugar, they need enough light, and then they need a large temperature difference between day and night to produce a large amount of sugar. In general, strong light in summer can meet the growth, but it is best to be cultivated in facilities, which can be artificially adjusted to extend the light, and the temperature can be adjusted, and the internal temperature can be increased during the day, as long as the watermelon adapts to the temperature, and then ventilated at night. Make the temperature the same as the outside world. Maximize the temperature difference between day and night.

Fourth, ploughing and weeding

Spraying herbicides before planting, and then growing grass at the seedling stage, it will be artificially pulled out to avoid competing for nutrients. Then the grass between rows will grow during the period of high temperature after rain, and the weeds can be hoed and turned into the soil to make green manure. Some of the weeds are about to fall when they are about to mature, and they will all be drugged to death before that. Don't pull up the grass by hand, avoid falling seeds, and continue to grow in the coming year.

The flowering and fruiting period of planting watermelon is an important management period, and a lot of work should be done to maintain flowering and growth and fruit. keeping flowers and fruits is the main work. Flowering and fruiting period is mainly in the summer period, so we must pay attention to the demand and regulation of temperature and light of watermelon, as well as centralized nutrition supply to high-quality flowers and fruits.
