The planting time of green winter melon, the planting method of green winter melon

Green peel winter melon is a winter melon variety that was introduced from Guangdong Province in the early 50s by vegetable farmers in the suburbs of Hangzhou, Zhejiang Province. Green-skinned winter melon is late-ripening, not waterlogg-resistant, disease-resistant, and prone to sunburn under high temperature and strong light. In Zhejiang Province, sowing seeds are sown from mid-February to mid-March, and planting is from early April to late April.

Sowing seedlings are raised in a solar greenhouse or a sunny furrow using a nutrient bowl or nutrient earthwork. The high-quality and well-rotted farmhouse manure and fertile soil are prepared in a ratio of 1:2 to prepare nutrient soil, mix and sieve, and load into a nutrient bowl or make a nutrient earth.

After drying, germination and sowing are sown and mulched in time to improve temperature and moisture. Small winter melon is more drought-tolerant, after watering enough water during sowing, the seedling stage is generally no longer watered, if the nutrient soil is too dry, you can water on a sunny day, pay attention to heat preservation and dissipation of moisture, seedling age 40-50 days, when the seedlings grow to four leaves or 5-8 leaves when the seedling age is planted.

It can also be cultivated by scaffolding or climbing, and trellis cultivation is higher yield and higher quality than climbing cultivation. Generally, 2500 3000 kg of organic fertilizer and 50 kg of superphosphate are applied per mu. The row spacing of intercropping tomato cultivation plants was 3 m 4, and the row spacing of climbing plants was 3 m.

When the temperature is strong, the melon surface is covered with grass to prevent sunburn. Harvested from late June to late August.

1. Sowing seedlings 1, seed treatment. Winter melon seeds are not easy to absorb water due to their thick seed coat, so they should be soaked and germinated and disinfected before sowing. The new high lipid film is soaked for 5-6 hours, scooped up for germination, and the germination temperature is about 30 for the warning, which can repel underground pests and diseases, isolate virus infection, do not affect the germination and swelling function, strengthen the respiration intensity, and improve the seed germination rate.

2. Seedlings. Sow early at the right time, and sow at the end of January to early February. After sowing, cover with a film arch to protect against the cold.

When the seedlings grow a leaf and a heart, transplant in the nutrient bag, the size of the nutrient bag is 15 18 cm, the nutrient soil is selected from the fertile soil that has not been planted with melon crops, and then covered with a film arch shed after planting to prevent cold. 2. Planting 1. Site selection. Choose new plots that have not been planted with melon crops or fields that have been rotated for 3-5 years.

2. Lifting the carriage and preparing the land. Make a box surface of 110-120 cm, the width of the ditch is 50 cm, and there is a ring ditch around the field, so that the ditch and the ditch are connected, which is convenient for drainage and irrigation. 3. Reasonable dense planting.

When the temperature is stable above 15 degrees Celsius, transplant on a sunny day, and remove the nutrient bag in front of the socks when planting. Each box is planted in a row, and the plant spacing is 60-70 cm. 450-550 plants are planted per mu, and the root water is drenched after planting.

After planting, spraying the new high-lipid film can effectively prevent the water on the ground from evaporating, the moisture of the seedling body from transpiring, isolate pests and diseases, shorten the seedling period, quickly adapt to the new environment, and grow healthily. 3. Fertilizer and water management 1. Apply sufficient basal fertilizer. The base fertilizer is buried in a long ditch in the middle of the box when the ground is prepared.

Apply 2000-3000 kg of organic fertilizer and 50 kg of superphosphate per mu. 2、

Summary. It is better to choose the previous crop is not a melon crop, and the land is well drained. The topography of the furrow is preferably from north to south.

It is better to choose the previous crop is not a melon crop, and the land is well drained. The topography of the furrow is preferably from north to south.

Planting method: Varieties of climbing winter melon are selected: the plant growth potential is better, the leaves are less, the vine division ability is poor, especially the anti-Japanese burning ability is strong, and the melon surface is white wax powder. Generally, the ability of green peel winter melon to resist anti-burning disease and dismantle is low, and it is not suitable for climbing planting. (2) The land preparation for climbing winter melon planting is selected with high and dry terrain, good drainage, and poor soil draft.

Apply basal fertilizer before planting, if the amount of fertilizer is large, you can first spread it all over the field, and then apply it in the planting ditch; If the amount of fertilizer is small, only concentrate on planting furrows. Then prepare the land to make furrows. The planting furrow of climbing winter melon is generally composed of two parts: planting furrow and creeping vine furrow, and the planting furrow and creeping vine furrow are arranged at intervals.

There are two types of furrow methods: one-way furrow and two-way furrow. The one-way furrow is 83 cm wide according to the furrow, the north and south furrows are listed as a group, the north furrow is planted furrow, the south furrow is climbing vine furrow, the north furrow is required to be built higher, and the furrow surface is slightly inclined to the south to block the north wind and prevent cold. You can also sow or plant lettuce first, and harvest the land when the melon spreads to the edge of the furrow, so that the melon vine can continue to stretch.

The two-way furrow is planted with a meter width according to the east-west extension direction, and then one parallel climbing furrow is made on the south side and the north side respectively, and the width of the furrow is about 83 cm. At the middle line of the planting furrow, the basal fertilizer was applied in a ditch, and two rows of winter melons were planted in the south and north on the base fertilizer, and then the southbound extension extended to the south and the northbound extended northward.

Winter melon planting time.

The cultivation of winter melon can be carried out in spring and autumn stoves, such as two seasons. Spring cultivation is generally carried out in January-February, Sichuan can be extended to February-March, and autumn cultivation is generally carried out in June-July. In different regions, the planting time will vary, depending on the local climate.

Winter melon growth cycle.

The whole growth and development process of winter melon from seed to seed varies greatly depending on the length of the species and varieties, ranging from 110-120 days for small seeds to 150-160 days for large seeds. According to its growth characteristics, it can be divided into four periods:1.

2.Seedling stage: the first true leaf of winter melon reveals the 6th and 7th true leaves.

At this time it grows erect and has a well-developed root system with taproots and lateral roots. Time 25-30 days. 3.

Period: It takes 20-30 days from the beginning of winter melon to the appearance of flower buds. At this time, the internodes are gradually elongated, from erect to crawling, the internodes absorb the tendrils, the axillary buds begin to move, and the lateral tendrils grow.

4.Flowering and fruiting period: The flowering and fruiting period of winter melon refers to the time from budding to fruit ripening, which takes 60 to 80 days.

Key points of winter melon planting technology.

1.Transplanting and planting: Winter melon seedlings can be transplanted when they grow to 2-3 true leaves.

The planting specifications are flat frame cultivation. The width of the ridge is about meters, and the distance between plants is meters. One acre of land can be ridge-resistant to about 600 plants, and about 500 plants per acre.

2.Whole vine pressing vine: Generally speaking, the main vine of winter melon should be removed in time, and the side vine should be removed before the fruit set.

3.Melon: Winter melon is generally in 25 and 32 sections, and the 3rd and 4th female flowers of the main vine are the most ideal.

When encountering bad weather when sitting melons, artificial pollination in the morning will improve the rate of melon setting. The selected young melon is cylindrical, with average size up and down, flat shoulder width and smooth fur.

The time of winter melon planting will have a certain gap according to the different climates of different regions, and there are generally two seasons for winter melon sowing, that is, spring and autumn.

That is, from December to March of the following year, it is considered spring sowing, and from July to September, it is generally regarded as a good autumn sowing. In fact, it seems that the line is sown all year round.

For example, the general sowing time in Guangzhou is January and February, while in Hunan it can be said that sowing can be carried out from December to September of the following year.

The southern region can plant winter melon in February or July every year, and the northern region should be planted in March and April every year.

Winter melon planting time is generally in spring and autumn, the specific time should be decided according to the climate of the region, if it is in the south where the temperature is suitable, it can be sown in January to February or July, if it is in the north, it is recommended to sow in spring, specifically in March to April.

The root system of winter melon is lush, the soil is fertile and deep, because the stems and leaves of winter melon are developed, the demand for water is greater, when the weather is warm in the seedling period, water once a day in the morning and evening, if the weather is cold, it is necessary to water less, when the melon vine climbs the frame, it is necessary to water the winter melon once a day.

Winter melon or clump growth period is long, the normal growth of the plant requires enough soil nutrients, in the process of maintenance, more fertilizer must be applied, when fertilizing winter melon, nitrogen fertilizer should be the mainstay, appropriate with the application of phosphorus and potassium cherry fertilizer, enhance the stress resistance of the plant, and improve the yield of a single fruit.

When the winter melon vine grows about 20 leaves, or blooms the second female flower, you can leave the melon, each plant can leave two to three melons, at this time you also need to remove the top buds, prune the old leaves, side branches.

As long as the next year's dongguan seeds are well preserved, not eaten by insects, and have no mildew, they can germinate normally. Self-kept aged winter melon seeds can be planted. Even if it is aged, the germination rate is very low.

Winter melon seed coat is thick, the treatment is not good and easy to cause rotten seeds, most of the seeds float on the water surface when soaking, and the buds are not neat when germinating, so winter melon. Aged winter melon seeds are not impossible to guess, it is best not to panicle seeds, the germination rate is low, and the growth is not good.

Winter melon and orange grandchildren are generally sown in spring and autumn, the specific time is 1-2 months and 7-8 months, and spring sowing is best to take seedling transplanting, autumn sowing is the use of bud sowing, which is more conducive to the growth of the plant in the later stage, greenhouse winter melon can be sown in January or June.

Winter melon is generally sown in spring and autumn, the specific time is 1-2 months and 7-8 months, and spring sowing is best to take the round chain seedling transplanting, autumn sowing is the use of bud sowing, which is more conducive to the growth of the plant in the later stage.

Greenhouse winter melon can be sown in January or June, so as to meet the needs of the winter market.

Winter melon origin and planting month.
