The latest course of pumpkin planting techniques and methods

Pumpkin alias pumpkin, pumpkin, rice melon, pumpkin, for the cucurbitaceae, pumpkin plants. Annual trailing herbs; stems often rooting at nodes, extending to 2-5 m, densely covered with white bristles. Petiole stout, native to Mexico to Central America, widely cultivated all over the world. It was introduced into China in the Ming Dynasty and is now widely planted in the north and south. The tender fruit is palatable and is one of the melons and vegetables in summer and autumn.

Construction of pumpkin planting garden

We should choose the land with high topography, good drainage, loose soil and good air permeability, preferably sandy loam and light loam, low-lying land prone to waterlogging is not suitable to grow pumpkin. The soil should be slightly acidic, and the PH value should be between 5.5 and 6.8. Avoid repeating and stubble with cucurbitaceae and Solanaceae crops to avoid serious occurrence of soil-borne diseases. Soil preparation should be fine. Before soil preparation, 3000 to 5000 kg of high-quality farm manure and 20 kg of diammonium phosphate should be applied every 667m2, and biological bacterial fertilizer can also be applied if possible.

Sowing time of pumpkin

The sowing time is determined according to the specific conditions of the year and the local conditions. The basic principle is to make the seedlings avoid the final frost and sow the seeds when they are unearthed. The Yangtze River basin is usually from February to April. Early sowing uses hotbed or cold bed to raise seedlings, and after mid-or late March, direct seeding can be done after budding. Seeds can be sown in South China from February to September. It is mainly divided into spring sowing from February to March and autumn sowing from August to September. The specific methods are as follows: soak the seeds in 55 to 60 ℃ hot water for 15 minutes, kill the bacteria on the surface of the seed coat, then pour into cold water to cool to 30 ℃, soak for 4 to 6 hours, wrap them in a wet cloth or towel and put them in 25 to 30 ℃ to accelerate germination to about 0.3cm before sowing. It can be planed according to 50 cm plant spacing, planing one ridge and one ridge, so that the plant row spacing is 50 × 120 cm, which is conducive to ventilation and light transmission and disease prevention. First water in the rice, after water infiltration, put 2 seeds flat per mu, seed buds face down, cover 2 to 3 cm fine soil, conditional plastic film can be covered, in fact, pumpkin row spacing is large, not much film is used, and only 10 yuan per mu is invested. But when covered with plastic film, we must break the bumpy cover, make the plastic film close to the ridge surface, tighten around and press into the soil, otherwise the effect of plastic film is not obvious, and the seedling generally does not need to be watered. When melon seedlings grow to 3 true leaves, choose large seedlings with strong plants and complete cotyledons. One plant is left in each plant, and the rest is cut off from the ground.

Herbicide weeding in planting garden

Before the weeds are unearthed, the ideal herbicides are 33% Tianpu, 100g / mu and 60kg / mu, or 25% Nongshita EC, 150g / mu and 60kg / mu. If weeds have been unearthed before sowing, you can use 41% Chunduoduo (glyphosate) to kill weeds by root and then sow them, spraying 200 to 300 milliliters per mu with 30 to 40 kilograms of water on the stems and leaves of weeds, which is generally effective for 6 to 7 days. The pesticide has no residue on the soil and will not cause any adverse effects on the crops transplanted in the current season or sown in the next crop. In order to improve the weed control and weeding effect of herbicides, several problems should be paid attention to during spraying, spraying evenly and not leaking, especially weeding before budding, should be sprayed backwards to prevent footprints from damaging the film and reduce the effect. Secondly, it should be watered or sprayed after rain during drought, so that the effect of weeding is better, and the dosage of sterilized herbicides should be increased during drought.
