When will the gourd grow seedlings? Mid-March in the South and April in the North

The time of raising seedlings of gourd varies according to different regions, and the most suitable temperature for raising seedlings is 20-25 ℃, so the south generally begins to sow seedlings in the middle of March, while in the north, because of the low temperature, seedlings are generally raised in the greenhouse in April, and need to be covered with plastic film after sowing, and then transplant when the temperature comes up in May.

When will the gourd grow seedlings?

1. The time for raising seedlings in the southern region is March.

Because the climate in the south is warm, and the most suitable growth temperature of gourd in the seedling stage is between 20-25 ℃, the seedlings can be raised in March in the south, and the seedlings should be raised in a good weather.

2. The time for raising seedlings in the northern region is April.

The temperature in the north is relatively low, so planting gourd in the north can be planted in April, it is best to choose to raise seedlings in a greenhouse, cover the seedling bed with plastic film after sowing, and wait until the temperature warms up in May. and then transplant it to the outside.

Select planting site

Planting land to choose in good drainage and fertile soil in the flat area, can also be in the two depressions and irrigation conditions, suitable for planting in corn, wheat, soybeans, can not be planted in white melons, watermelons and other melons, there are closed herbicides can not be planted in places, planting ridges for the long mouth ridge, ridge width between 90-130cm.

Indoor budding

Japanese green gourd varieties can be selected, soaked in 35 ℃ warm water for 12-24 hours, then removed and wrapped with gauze to dry, covered with quilts to accelerate germination, brush twice a day, not too much, to avoid stagnant water in the seed coat, germination temperature is about 25 ℃, then put in a cool and dry place, waiting for its germination can be sown.

Prepare the seedbed

The nursery bed can use horse dung or broken grass as a base pad of 8-10cm, spread some soil on it and tread flat, and then disinfect it with 70% dexamethasone wettable powder, 0.3-0.6 g per square meter. Choose the soil that has not used herbicides such as Pushter and Dosulfuron, and then stir the screened rotten farm manure at 7:3.

Put the nutrient soil into the plastic bag, then put about 30 grains of diammonium at the bottom of the plastic bag as the base fertilizer, cut the bottom corner of the nutrition bag to facilitate water penetration, place the nutrition bag on the seedbed, keep the gap 1cm, then pour enough water, and then sow seeds after the surface of the soil is dry.

Sowing at the right time

The sowing time of the gourd is from March to May. A wooden stick can be used to insert a 3-4cm deep hole in the middle of the nutrition bag to put the germinated seeds into the soil with the bud eyes facing down, and then water once again.

Later stage management

Artificial weeding should be carried out during the planting period, and timely prevention and control of diseases and insect pests should be carried out. Can be watered when the main vine grows to 50cm or so. In the later stage, urea is applied to each plant. Do not get too close to the rhizome, avoid burning roots, do not spread urea into the leaves, avoid burning leaves, and even empty ridges to avoid grass famine. After that, cover the empty ridges with wheat straw or rice straw 1kg per square meter.

Smooth vines: each plant leaves 2 main vines, 2 main vines cross the air compression, during which directional soil can be cultivated once, so that melon seedlings can grow smoothly.

Pinching and bifurcation: when it grows to 3 leaves, it is necessary to begin to pinch off the second or third branching, and the pinching of the main vine is generally after August.

Artificial pollination: the gourd does not blossom in the morning and rainy days, so it can be branched and pinched every morning, but pollination begins at 4 p.m., and pollination will be suspended after the office (August 23). Usually the two main vines will bear melons or so.

Harvest and processing

It began to be harvested gradually in early August. When the first stubble melon grows to 15-18 jin, it can be harvested with a sound from your fingernails. After the first day of harvest, you should cut melon strips on the second day. Do not cut melon strips on rainy days.

The specification of the wooden frame for drying needs to be 2.2 meters high, 3 meters wide and 18 meters long, and two rows of wooden poles should be wrapped with plastic film to avoid sticking melon strips. The drying site can be chosen in the field, where there is less dust, and there is a lot of dust in the courtyard or on the road in front of the door. you need to be covered with plastic sheeting to avoid falling into dust. it is appropriate to touch your hands without sticking your hands when drying.

Usually cut melon sticks into the room in the afternoon, the second day out of the room to air, and then turn the pole to avoid sticky melon, 80% dry, divided into long and short strips and then into the room fumigation, usually fumigation time for 2 nights, 24 hours or so, each hectare with sulfur 200kg or so, each room with sulfur to prevail, usually 3000 jin melon sticks, each time about 3 jin, the amount of sulfur and climate, sunny days should be less cloudy days.

After leaving the room, pack it in a plastic bag and tie a small handle with a diameter of 3cm to avoid the smell of sulfur. The length of melon strips should be 1.8-2.2m, wide 2.5cm and thick 3mm. During this period, there are no aging strips, pimps, dirty strips, snake pimps, Youtiao, tendons and melons, and the moisture content is generally about 20%.
