Cultivation and management techniques of watermelon listed in advance

In recent years, there are more and more out-of-season melons and fruits, because people gradually understand that if goods can enter the market ahead of time, they can quickly occupy the market and gain greater economic benefits. The same is true of watermelons. With the continuous development of planting technology, some areas can eat watermelons on the market around April, so how does the technology of watermelons appear on the market in advance? Let's take a look at it together.

I. seed selection for early listing of watermelons

The selection of watermelons needs to pay attention to two points: one is the adaptability of watermelons to the climate of the planting area, and the other is the market sales of watermelons. With regard to climate adaptability, growers can choose suitable melon seedlings according to local climatic conditions. With regard to market adaptability, there are mainly two kinds of melon shapes on the market at present, one is seeded watermelon, the other is seedless watermelon. Planting experience tells us that seeded watermelon can achieve early maturity through a series of planting techniques, appear on the market in advance, and the ripening period of seedless watermelon is relatively long. Growers can choose two types of watermelons: seeded watermelon and seedless watermelon, and the best ratio is 4: 6. The use of these two physical techniques for pest control can effectively eliminate most of the pests that seriously harm the growth of melon seedlings, such as nocturnal moth pests and fly aphid pests. Seeded watermelons can be used by farmers and merchants to appear on the market in advance and occupy the market, while seedless watermelons can be made up later and consolidate the market. the combination of the two can benefit growers and businesses to obtain considerable economic benefits. it can also meet the needs of consumers. At present, there are varieties of black beauty series with better planting effect in the field, and Nongyouxin No. 1 is the seedless watermelon, which farmers can choose reasonably.

Second, reasonable and timely sowing

In order to put watermelons on the market in advance, it is very important to choose the right sowing time, and it is necessary to adopt scientific and reasonable sowing methods. Timely sowing needs to consider the local climatic conditions, temperature and other factors. Take the author's place as an example: the average temperature in winter and spring is 14 degrees Celsius, and the temperature rises gradually after March. Growers can sow seeds and raise seedlings in greenhouses in December and January of next year, and farmers will be able to transplant watermelon seedlings to greenhouse sheds in the field at the end of January and early February. The matters needing attention in the work of sowing and raising seedlings are as follows: first, the seeds must be disinfected before sowing and do a good job of preventing diseases; second, after the seeds sprout, it is necessary to ensure the abundance of water and nutrition in the roots; third, the intensity of light needs to be artificially enhanced.

III. Thermal insulation cultivation of field management

In order to put watermelons on the market ahead of time, it is necessary to sow and raise seedlings early, that is, around December in winter. The use of these two physical techniques for pest control can effectively eliminate most of the pests that seriously harm the growth of melon seedlings, such as nocturnal moth pests and fly aphids, which are relatively cold in winter and December. Only by ensuring the appropriate temperature can the sowing and breeding of watermelon be carried out normally. The initial stage of sowing and seedling cultivation has more stringent temperature requirements, so this stage is carried out in the greenhouse, waiting for the watermelon seedlings to grow for about a month before being transplanted into the greenhouse in the field. In short, in order to put watermelons on the market in advance, temperature is the key in the process of watermelon planting, so the planting method in the greenhouse is the main means.

IV. Reasonable close planting of seedlings between field management

After the watermelon seedlings in the field greenhouse grow to a certain stage, there will be the phenomenon of melon seedlings intertwining with each other, this is because the density of melon seedlings in some areas is too high, so it is necessary to carry out field seedlings. Excessive density of melon seedlings will seriously affect the normal growth of watermelon seedlings, which is not conducive to watermelon listing in advance. However, if the planting density is too low and too sparse, it will directly affect the yield of watermelon. Therefore, according to the actual situation of their own melon fields, growers must reasonably plan the number of melon seedlings per unit area of their own melon fields, plant them in close density reasonably, and carry out the work of seedlings in the field in time.

V. Irrigation techniques for field management

The planting process of watermelon is very draught, so it is necessary to ensure that the amount of water is abundant and actively irrigated in order to ensure that watermelons are put on the market in advance. The irrigation of watermelon field planting management should adhere to the principle of "more frequency, less dosage". This kind of irrigation method is more beneficial to the growth of watermelon. The irrigation technology that accords with this principle is the drip irrigation technology under plastic film which is widely used now. This irrigation technology can not only ensure the abundance of water in the watermelon field through all-weather spraying, but also save water.

VI. Pest control in field management

In the process of watermelon planting, in order to achieve watermelon listing in advance, it is necessary to ensure the normal growth of watermelon and avoid the influence of insect pests. The use of pesticides is a method, but with the development of science and technology, we can minimize the use of pesticides by planting watermelons today. after all, the use of pesticides has too many dominant and hidden negative effects. Farmers can control insect pests by using physical techniques such as frequency vibrating insecticidal lamps and trapping yellow boards. In the greenhouse in Daejeon, one frequency vibrating insecticidal lamp is installed on an average of three to four square meters, and three to four insect trapping yellow boards with an area of 20 centimeters by 40 centimeters are hung every 100 square meters. The use of these two physical techniques for pest control can effectively eliminate most of the pests that seriously harm the growth of melon seedlings, such as nocturnal moth pests and fly aphid pests. Moreover, the economic input of frequency vibrating insecticidal lamp and insect trapping yellow board is one-time, can be used for a long time, and can effectively reduce the planting cost of growers. In addition, the use of physical technology does not have a series of negative effects of the use of pesticides, which not only has a good effect of killing insects, but also can ensure the good quality of watermelon and improve the safety and quality of watermelon.

The above is the pro-agricultural network for everyone to collect and sort out the cultivation techniques of watermelons on the market in advance, fruit growers can refer to as appropriate. This technology can not only ensure the quality of watermelons, but also achieve the early listing of watermelons, and the early listing of watermelons can not only let consumers taste delicious watermelons as soon as possible, but also improve the economic benefits of fruit growers, which can be said to kill two birds with one stone.
