How about planting seedless watermelons in 2020? Which variety is better? Attached cultivation techniques

Summer without watermelons is not complete, summer heat to a cool watermelon, the whole summer has become cooler. So how about planting seedless watermelons in 2020? Which variety is better? Let's take a look at it.

How about planting seedless watermelons in 2020?

Summer watermelon sales are very high, almost every household will choose to buy watermelons, among which seedless watermelons are very popular. With the continuous progress of planting technology, the yield of seedless watermelon is also increasing, and the yield of seedless watermelon per mu can reach about 4 tons. Judging from the price of seedless watermelon in 2019, the price is 0.6-1.2 yuan per catty. It is expected that the price in 2020 and 2019 will not fluctuate much, and the profit from planting is still considerable.

Second, what kind of varieties should be planted?

1. Yuyi Tiansheng seedless watermelon: pure black skin, medium maturity, full growth period of 100days, easy to sit melon, single melon weight 8~10kg, good quality, resistant to storage and transportation.

2. Yuyi 926 seedless watermelon: Jingxin skin color, mid-early maturity, the whole growth period of 100 days, sugar content as high as 13%, excellent quality.

3. Huabao seedless No. 2 watermelon: peel, mid-late maturity, single melon weight 8kg or so, good quality, easy to sit melon, and resistant to continuous cropping, good disease resistance.

4. Yuyi sweet seedless watermelon: precocious, easy to sit, steady growth, heavy 7~8kg per melon, good quality.

3. Cultivation techniques of seedless watermelon

1. Breaking the shell to accelerate budding

Broken shell: seedless watermelon seed embryo development is poor, and the seed coat is thick, so the shell must be broken before budding, that is, after soaking the seed for 6-8 hours, gently open the seed coat with teeth without damaging the seed kernel, and then accelerate the germination.

Sprouting: the budding rate can reach more than 70% after budding at 33-35 ℃ for 36-48 hours.

2. Sowing seeds at the right time

For raising seedlings in solar greenhouse or arch greenhouse, the planting period can be arranged in late April, and the seedling raising in open field can be postponed to the middle and late April. If plastic film mulching is used to raise seedlings, it can be 5-7 days earlier than that in open field.

3. Colonization

The planting of seedless watermelon should be sparse, 500 plants per mu, 2.5 m row spacing and 0.6 m plant spacing, and 600 small fruit varieties per mu. It is best to choose loam and sandy loam which are not easy to accumulate water and facilitate drainage and irrigation. before planting, apply sufficient base fertilizer combined with soil preparation, deep ploughing and fine harrowing is required, and then hit the high border according to 2.5m wide to prepare for planting. Before planting, the nutrition bowl should be watered once before planting, and the melon seedlings should be planted near the edge of each border according to 0.6 m plant distance (easy to water). Watering the seedlings once after planting, the common seeded watermelon seedlings for pollination can be planted according to the method of one row of pollinated watermelons every 5 rows, which is convenient for management and harvest.

4. Pest control

Fusarium wilt: avoid continuous cropping; grafting seedlings; 667 square meters with heavy stubble Ling 400g, before soil preparation, sprinkle evenly, foliar spray wilt disease 600 times as much as 800 times during the growing period.

Anthracnose and blight: spraying 500 times of Jianzhibao every 7 to 10 days before the onset of anthracnose has a better preventive effect; after the onset of anthracnose, it can be sprayed with 900 times of carbendazim, or 800 times of 75% chlorothalonil, or 800 times of well-intentioned fungicides; after the onset of the disease, 58% of the solution can be sprayed on the leaf, or 700 times of 72% frost.

Virus disease: spraying 500 times of Jianzhibao liquid once every 7 days during the growing period also has a good preventive effect. After the disease, foliar spray Kangrun 2 tablets + Wanshuai No. 1 30g + Jianzhibao 30ml can be used to prevent and cure water 15kg.

Huangshou melon: 1000 times of Lexben solution is sprayed on the leaves of the adult stage, 1000 times of the trichlorfon solution can be used to kill the larvae in the larval stage, and plant ash is scattered around the plant to prevent adults from laying eggs during the oviposition period.

Melon aphid: control with 40% Lesben 900x solution, 6000 fold solution or 2.5% Kungfu EC 4000 times solution.

The prospect of planting seedless watermelons is still very good. Before planting, it is best to choose watermelons in line with the local environment and market conditions.
