"Natural insulin" balsam pear apply what fertilizer is good? How to apply fertilizer in each growing period? How much fertilizer does one mu of land need?

Balsam pear is a kind of vegetable planted in the north and south of our country. It is deeply loved by people because of its effects of heat-clearing and detoxification, lowering blood sugar, beauty and beauty. At present, balsam pear is planted in many areas, but if you want to plant balsam pear well, you need to do a good job of management. what kind of fertilizer should be applied to balsam pear? How to apply fertilizer in each growing period? How much fertilizer does one mu of land need?

1. Base fertilizer of balsam pear

Balsam pear is not strict on soil conditions, but like fertilizer and water, avoid continuous cropping, it is appropriate to choose clay loam soil which has not planted melon crops for 3 consecutive years, deep soil layer, high organic matter content, fertilizer and water conservation. Before planting, apply sufficient base fertilizer, 4000kg / mu of fully mature organic fertilizer and 20kg / mu of three-element compound fertilizer. A ploughing was carried out after spreading fertilizer. Open-field cultivation is generally made into flat or high beds 150 cm wide; greenhouses can be sparsely planted and can be made into ridges of 60 cm and 80 cm or high beds 150 cm wide.

2. Topdressing of balsam pear

Balsam pear has more female flowers, can continue to blossom and bear fruit, pick one after another, and the harvest period is longer, so the growth period of balsam pear needs to consume a lot of fertilizer and water for a long life. In addition to applying sufficient base fertilizer, in the middle and later stages of fruit production, great attention should be paid to timely topdressing and irrigation. Generally, after entering the melon harvest period, water can be watered once every 7 to 10 days, and chemical fertilizer can be applied with water every other time. The amount of topdressing is 10: 15 kg urea per mu, or 10-15 kg of three-element compound fertilizer can be applied. In the full fruit period, phosphate fertilizer should be applied 2 times and 10 kg superphosphate each time. In the later stage of fruit, attention should be paid to strengthening the supply of fertilizer and water. Otherwise, it is easy to get rid of fattening and early senescence, plant growth is thin, leaf color is yellow-green, lateral branches are weak, melon is few, melon is small, yield is low, bitterness is strong, and quality becomes worse.

Balsam pear topdressing should adopt the way of centralized fertilization, such as digging annular ditch, etc., which can greatly improve the utilization rate of fertilizer.

Specific method: dig a circular ditch at 20 cm inside the balsam pear plant, or dig a 0.5 m long strip ditch at 20 cm inside the balsam pear plant, and then apply the fertilizer into the ditch and bury the ditch with soil before watering. It should be noted that balsam pear must be watered in time after each topdressing, so that the effect of plant nutrient absorption is good.

Third, the wrong fertilization method of balsam pear

1. Dashuichong fertilizer: the common way of topdressing balsam pear netizens is to apply fertilizer with water, which is very convenient, and the fertilizer can be applied evenly into the soil, but balsam pear topdressing in this way is not advisable. The reason is that the number of balsam pear plants per mu is less, only 200 plants per mu, if you adopt the way of topdressing with water, the fertilizer use efficiency will be very low and the waste will be serious. Therefore, centralized fertilization should be adopted, which is not only conducive to crop absorption, but also improve the utilization rate of fertilizer.

2. Partial application and heavy application of nitrogen fertilizer: although balsam pear needs more nitrogen fertilizer, excessive application of nitrogen fertilizer can not only lead to excessive growth of balsam pear plant, affect yield and quality, but also reduce the stress resistance of balsam pear and aggravate the occurrence of balsam pear disease. at the same time, it is also easy to produce malformed gourd.
